AB  - Due to the promising applications of propolis as a natural food preservative, functional ingredient or supplement, on one side, and the inherent toxicity and high volatility of organic solvents used for extraction of phenolics from propolis, a range of natural eutectic solvents (NESs) was evaluated for the extraction of phenolic compounds from poplar type propolis to create “green-labelled” food products. The phenolic profile of novel green propolis extracts was evaluated using high-performance thin-layer chromatography, while 16 phenolic compounds were quantified by ultra-high-performance liquid chromatography hyphenated with mass spectrometry. Pinocembrin and chrysin were the most dominant phenolics with an average concentration of 3111 and 3039 mg/kg in lactic acid-based NES, respectively. Biological activity, such as antioxidative and antimicrobial activities, were determined using spectrophotometric and well diffusion methods. Considering all spectrophotometric assays lactic acid-based presented as the best extraction medium for phenolic extraction, with TPC, TFC and RSA values 150.0 mg GAE/g, 190.0 mg RUE/g, and 132.8 mg TE/g on average, respectively. From 38 studied NESs, choline-chloride:tartaric acid (1:1 n/n), glycerol:lactic acid (1:1 n/n) and glycine: lactic acid (1:3 n/n) were the most promising extraction medium for obtaining the propolis extracts enriched with bioactive compounds. Additionally, proposed green solvents were proved to be the designer solvents and showed potential to be tuned to target specific phenolic compounds. Improved, or at least maintained, biological activity of NES propolis extracts support its application in agriculture industry.

AB  - In the present study, we investigated in vitro the antimicrobial activity of the pygidial gland secretion of the guanophilic ground beetle Laemostenus (Pristonychus) punctatus (Dejean, 1828) and some of its chemicals against resistant and non-resistant bacteria and Candida species, the synergistic and additive potential of combinations of selected chemicals and antimicrobial drugs against resistant bacterial and fungal strains, anti-adhesive and anti-invasive potential of the secretion and formic acid alone and in selected combinations with antimicrobial drugs against methicillin-resistant Staphylococcus aureus (MRSA) toward spontaneously immortalized human keratinocyte cell line (HaCaT cells). In addition, we examined the antiproliferative activity of the secretion and formic acid in vitro. The tested secretion and the standards of formic and oleic acids possessed a significant level of antimicrobial potential against all tested strains (P < 0.05). The isolate from guano Pseudomonas monteilii showed the highest resistance to the secretion and formic acid, while MRSA achieved a significantly high level of susceptibility to all agents tested, particularly to the combinations of formic acid and antibiotics, but at the same time showed a certain level of resistance to the antibiotics tested individually. Candida albicans and C. tropicalis were found to be the most sensitive fungal strains to the secretion. Formic acid (MIC 0.0005 mg/mL) and gentamicin (MIC 0.0010 mg/mL) in the mixture achieved synergistic antibacterial activity against MRSA (FICI = 0.5, P < 0.05). The combination of formic acid, gentamicin and ampicillin accomplished an additive effect against this resistant bacterial strain (FICI = 1.5, P < 0.05). The secretion achieved a better inhibitory effect on the adhesion ability of MRSA toward HaCaT cells compared to formic acid alone, while formic acid showed better results regarding the invasion (P < 0.001). The combinations of gentamicin and ampicillin, as well as of formic acid and gentamicin and ampicillin achieved similar anti-adhesive and anti-invasive effects, with a slight advantage of formic acid and antibiotics in combination (P < 0.001). The secretion and formic acid were found to be non-toxic to HaCaT cells in vitro (IC50 ≥ 401 μg/mL).

AB  - The pygidial glands of carabids produce strong-smelling vapours. In this study, we examined the chemical composition of the gland secretions and the structure of the glands in five species of Carabini ground beetles (one species from the subtribe Calosomatina and four species from the subtribe Carabina): Calosoma (Calosoma) maderae (Fabricius, 1775), Carabus (Carabus) granulatus Linnaeus, 1758, C. (Limnocarabus) clathratus Linnaeus, 1760, C. (Carabus) ulrichii Germar, 1823, and C. (Procerus) gigas Creutzer, 1799. Additionally, we tested the antibacterial potential of the pygidial gland secretions of the two latter species against 11 bacterial strains. In order to detect the chemical content of the secretions, we used gas chromatography–mass spectrometry (GC–MS). The secretion extracts were applied against selected strains of medically important bacteria. We used bright-field microscopy to examine the morphology of the glands. We discovered a total of 11 chemical compounds in the pygidial gland extracts of the ground beetles we analysed. Ten of these compounds were identified as seven carboxylic acids, two hydrocarbons, and one aromatic aldehyde, while one chemical remained unidentified. Most of the components were isolated from the secretion of C. (L.) clathratus (nine), while the lowest number of compounds was found in C. (P.) gigas (two). Methacrylic acid was the most dominant compound by percentage in all five species, while angelic acid was also detected in all samples. As expected, salicylaldehyde was exclusively found in the species of the genus Calosoma Weber, 1801. The secretion of C. (P.) gigas was shown to achieve the highest level of antibacterial activity against Pseudomonas aeruginosa, Salmonella enterica, and S. typhimurium (even the same level as the positive control streptomycin), while the secretion of C. (C.) ulrichii achieved the highest antimicrobial potential against Staphylococcus epidermidis, S. aureus, Listeria monocytogenes, and Bacillus cereus. The most noticeable difference in the structure of the glands between the two genera is that the reservoir in Calosoma is more significantly narrowed as it leads into the efferent duct, compared to that of Carabus.

AB  - Structural modification of different carbon-based nanomaterials is often necessary to
improve their morphology and optical properties, particularly the incorporation of N-atoms in
graphene quantum dots (GQDs). Here, a clean, simple, one-step, and eco-friendly method for
N-doping of GQDs using gamma irradiation is reported. GQDs were irradiated in the presence
of the different ethylenediamine (EDA) amounts (1 g, 5 g, and 10 g) and the highest % of N was
detected in the presence of 10 g. N-doped GQDs emitted strong, blue photoluminescence (PL).
Photoluminescence quantum yield was increased from 1.45, as obtained for non-irradiated dots,
to 7.24% for those irradiated in the presence of 1 g of EDA. Modified GQDs were investigated as
a PL probe for the detection of insecticide Carbofuran (2,2-Dimethyl-2,3-dihydro-1-benzofuran-7-
yl methylcarbamate) and herbicide Amitrole (3-amino-1,2,4-triazole). The limit of detection was
5.4 µmol L−1
for Carbofuran. For the first time, Amitrole was detected by GQDs in a turn-off/turn-on
mechanism using Pd(II) ions as a quenching agent. First, Pd(II) ions were quenched (turn-off) PL
of GQDs, while after Amitrole addition, PL was recovered linearly with Amitrole concentration
(turn-on). LOD was 2.03 µmol L−1
. These results suggest that modified GQDs can be used as an
efficient new material for Carbofuran and Amitrole detection. Furthermore, the phototoxicity of dots
was investigated on both Gram-positive and Gram-negative bacterial strains. When bacterial cells
were exposed to different GQD concentrations and illuminated with light of 470 nm wavelength, the
toxic effects were not observed.

AB  - Antibacterial and antibiofilm efficacy through a synergistic effect of herbal leaf extracts of bearberry (BE), bearberry tea (BTE), parsley (PE), and the strawberry tree (STE) was evaluated to discover an alternative approach to control urinary tract infections caused by Enterococci. UHPLC–DAD MS/MS analysis indicated that herbal extracts were rich in ellagic and gallic acids, catechin, quercetin, and arbutin, which are strong antioxidants. Mostly, Enterococcus faecalis isolates showed resistance only to gentamicin and/or norfloxacin (26.3 %) and moderate biofilm production (31.5 %), while 12 isolates of Enterococcus faecium showed multiple antibiotic resistance. The minimum inhibitory concentration for the majority of isolates was 1.25 mg ml−1 for STE, but 2.5 mg ml−1 for BE and BTE. Although individual extracts gave higher MIC values, for most isolates, a synergistic effect at lower concentrations was achieved, when BE or BTE (0.625 mg ml−1) was combined with STE (0.31 mg ml−1). The BTE extract was shown to have the strongest individual effect on initial adhesiveness and on biofilm formation to all selected isolates, while the synergism of BTE and STE caused significant biofilm inhibition at all concentrations tested. The synergistic effect achieved of the tested extract combinations might be a starting point in the development of alternative products, effective against antibiotic resistant Enterococcus isolates.

AB  - Aims: A multidisciplinary approach was used to compare phenolic composition, radical scavenging and antimicrobial activity of propolis samples from different geographical localities, and plant resin against various microorganisms. Methods and Results: Using UHPLC-qqqMS quantitative analysis, 28 phenolic compounds were determined. Caffeic and p-coumaric acids were identified as main phenolic acids in poplar propolis samples, except samples from Russia (P6) and China (P7). Radical scavenging activity (applying DPPH spectrophotometric assay) showed the highest activity of Serbian (40·51%) and Chinese (53·21%) propolis samples. Broth microdilution method was used for the oral cavity, fungal phytopathogenic and human vaginal isolates which have been identified at a molecular level. The most sensitive bacterial isolates were Lactobacillus acidophilus (MIC of 0·03–0·13 mg ml−1) and the oral streptococci isolates (MIC values of 0·19–0·13 mg ml−1). The most sensitive fungal phytopathogenic isolate was Fusarium oxysporum (MIC 0·003 mg ml−1). All samples, except propolis from Serbia (P4) and Turkey (P5), showed a strong antifungal activity against Fusarium sporotrichioides, Fusarium subglutinans and Fusarium proliferatum. Conclusion: The results of various tests indicate good radical scavenging and antimicrobial activity against important human and plant pathogens. Significance and Impact of the Study: A detailed propolis analysis is important when proposing a preparation of new biological antimicrobial products which have a positive impact on human health and reduce antibacterial resistance.

AB  - The main focus of this study is to assess radical scavenging and antimicrobial activities of the 11 wood extracts: oak (Quercus petraea (Matt.) Liebl., Q. robur L., and Q. cerris L.), mulberry (Morus alba L.), myrobalan plum (Prunus cerasifera Ehrh.), black locust (Robinia pseudoacacia L.), and wild cherry (Prunus avium L.). High-performance thin-layer chromatography (HPTLC) provided initial phenolic screening and revealed di erent chemical patterns among investigated wood extracts. To identify individual compounds with radical scavenging activity DPPH-HPTLC, assay was applied. Gallic acid, ferulic and/or ca eic acids were identified as the compounds with the highest contribution of total radical scavenging activity. Principal component analysis was applied on the data set obtained from HPTLC chromatogram to classify samples based on chemical fingerprints: Quercus spp. formed separate clusters from the other wood samples. The wood extracts were evaluated for their antimicrobial activity against eight representative human and opportunistic pathogens. The lowest minimum inhibitory concentration (MIC) was recorded against Staphylococcus aureus for black locust, cherry and mulberry wood extracts. This work provided simple, low-cost and high-throughput screening of phenolic compounds and assessments of the radical scavenging properties of selected individual metabolites from natural matrix that contributed to scavenge free radicals.

AB  - Linden tea has been used in Serbian folk medicine for centuries to induce sweating for colds, relieve throat irritation and cough, reduce blood pressure, as well as a diuretic, spasmolytic, and as a sedative. The main aim of this study was to determine the comprehensive metabolite profile, free radical scavenging activity, and antimicrobial activities against 23 human and plant pathogens of both commercial and field-collected linden tea samples from Serbia. Developed high-performance thin-layer chromatography (HPTLC) method allowed identification of eight major metabolites in investigated samples, while forty-six metabolites were tentatively identified using high resolution mass spectrometry (HRMS): 14 phenolic acids and their derivatives, 15 glycosides, 9 flavonoids, and 8 procyanidins. Both commercial and field-collected linden tea samples showed similar total phenolic content and radical scavenging activity. Seven compounds such as p-hydroxybenzoic acid 4-O-hexoside, caffeic acid cinnamyl ester, pinocembrin, galangin, luteolin 7-O-glucuronide (and its isomer), isorhamnetin hexosyl hexoside were found in Tilia samples for the first time. Radical reagent 2,2-Diphenyl-1-picrylhydrazyl· (DPPH·) was used in DPPH-HPTLC assay which identified chlorogenic acid, caffeic acid, astragalin, quercitrin, tiliroside, and rutin as compounds that exhibit radical scavenging activity. Tilia samples showed inhibitory effect overwhelming only on Gram-positive bacteria, especially on Bacillus subtilis with the lowest MIC values observed, as well as towards Staphylococcus aureus and oral cavity isolates of Streptococcus pyogenes and Streptococcus mutans. Vaginal isolate of Candida glabrata showed more susceptibility than Candida albicans isolate. Generally, extract from Tilia cordata Miller (L4) showed the highest antimicrobial activity against the most of the tested pathogens, among all field-collected Tilia samples.

AB  - Ethnobotanical and ethnopharmacological studies of many Centaurea species indicated their potential in folk medicine so far. However, investigations of different Centaurea calcitrapa L. extracts in terms of cytotoxicity and antimicrobial activity against phytopathogens are generally scarce. The phenolic profile and broad antimicrobial activity (especially towards bacterial phytopathogens) of methanol (MeOH), 70% ethanol (EtOH), ethyl-acetate (EtOAc), 50% acetone (Me2CO) and dichloromethane: methanol (DCM: MeOH, 1: 1) extracts of C. calcitrapa leaves and their potential toxicity on MRC-5 cell line were investigated for the first time. A total of 55 phenolic compounds were identified: 30 phenolic acids and their derivatives, 25 flavonoid glycosides and aglycones. This is also the first report of the presence of centaureidin, jaceidin, kaempferide, nepetin, flavonoid glycosides, phenolic acids and their esters in C. calcitrapa extracts. The best results were obtained with EtOAc extract with lowest MIC values expressed in µg/mL ranging from 13 to 25, while methicillin resistant Staphylococcus aureus was the most susceptible strain. The most susceptible phytopathogens were Pseudomonas syringae pv. syringae, Xanthomonas campestris pv. campestris and Agrobacterium tumefaciens. The highest cytotoxicity was recorded for EtOAc and Me2CO extracts with the lowest relative and absolute IC50 values between 88 and 102 µg/mL, while EtOH extract was the least toxic with predicted relative IC50 value of 1578 µg/mL. Our results indicate that all tested extracts at concentration considered as non-toxic can be one of great importance in combat towards phytopathogenic and human pathogenic strains, as well as natural sources of antimicrobials.

AB  - European plum (Prunus domestica L.) is a significant commercial crop in Serbia in terms of total fruit production, and is traditionally processed into slivovitz brandy. The brown rot disease caused by Monilinia laxa drastically reduces plum yield almost every year. Fungal communities associated with leaves and fruits of four local Serbian plum cultivars (Požegača, Ranka, Čačanska Lepotica and Čačanska Rodna) were investigated in two phenological stages during early (May) and late (July) fruit maturation. Alpha diversity indices showed that fungal communities were heterogeneous and Beta diversity indicated that autochthonous fungal communities depended upon seasonal changes and the cultivars themselves. The phylum Ascomycota was the most abundant in all samples, with relative abundance (RA) between 46% in the Požegača cultivar (May) and 89% in the Lepotica cultivar (July). The most abundant genus for all plum cultivars in May was Aureobasidium, with RA from 19.27 to 33.69%, followed by Cryptococcus, with 4.8 to 48.80%. In July, besides Cryptococcus, different genera (Metschnikowia, Fusarium, and Hanseniaspora) were dominant on particular cultivars. Among all cultivable fungi, molecular identification of eleven M. laxa isolates from four plum cultivars was performed simultaneously. Bacterial isolates from the plum phyllosphere were tested for their potential antifungal activity against indigenous M. laxa isolates. The most potent antagonist P4/16_1, which significantly reduced mycelial growth of M. laxa, was identified as Pseudomonas synxantha. Further characterization of P4/16_1 revealed the production of volatile organic compounds and phenazine-1-carboxylic acid (PCA). Crude benzene extract of PCA exhibited 57–63% mycelial growth inhibition of M. laxa. LC/MS analysis of the crude extract confirmed the presence of phenazine derivatives amongst other compounds. Scanning electron microscopy revealed morpho-physiological changes in the hyphae of M. laxa isolates caused by the cell culture and the P. synxantha P4/16_1 crude benzene extract. This is the first report of antagonistic activity of P. synxantha against M. laxa induced by diffusible and volatile antifungal compounds, and it appears to be a promising candidate for further investigation for potential use as a biocontrol agent against brown rot-causing fungi.

AB  - Bacillus species produce a wide array of biologically active metabolites, including nonribosomaly synthesized lipopeptides (LPs). The high-performance thin-layer chromatography (HPTLC) technique hyphenated with different bioassays and mass spectrometry was demonstrated as a valuable tool for effect-directed analysis of iturins, surfactins, fengycins and kurstakins homologues from complex mixtures of LPs. As proof of this straightforward strategy, the found surfactin and iturin A homologues were characterized and compared with reference substances. This study considered two different extraction methods for LPs produced by five Bacillus strains. The ethyl acetate extraction (Ex-1), and the acidic precipitation followed by methanol extraction (Ex-2) were investigated. Diverse enzyme inhibitions and antimicrobial potentials of LPs were analyzed, and in parallel, high-resolution mass spectra (HRMS) were online recorded from the HPTLC zones of interest. No antimicrobial effect against Gram-positive B. subtilis was evident for iturin, whereas a response was detected for surfactin. The nonpolar kurstakin compounds showed a pronounced B. subtilis antimicrobial activity in Ex-1 of almost all strains, whereas the fengycin homologues were detected in Ex-2 of SS-10.7 and SS-27.2. Iturin had also no activity against Gram-negative Aliivibrio fischeri, while again surfactin showed an enhancing luminescent activity. Contrary, kurstakin compounds caused a decrease in the luminescence in Ex-1 of all strains, particularly for SS-13.1. Both, iturin and surfactin showed a strong acetylcholinesterase (AChE) and α-glucosidase inhibition, but surfactin caused a much stronger inhibition. This was evident in all bacterial strains, except for SS-13.1 in Ex-1 and for SS-38.4 in Ex-2. Although, iturin and surfactin exhibited no DPPH˙ scavenging activity, Ex-1 of all strains contained more intense DPPH˙ scavenging compounds compared to Ex-2, and surfactin methyl esters showed a pronounced DPPH˙ activity, particularly in SS-12.6 in Ex-1. This study pointed to active metabolites of strains that can be used as therapeutics and biocontrol agents with beneficial effects on human health. The straightforward HPTLC profiling served as an excellent bioanalytical tool to control the formed bioactive metabolites. As the fermentation process is very sensitive to external influences, it could be a helpful control tool for standardization of the biotechnological processing.

AB  - Ethnopharmacological relevance: Essential oils obtained from resins of Boswellia carteri Birdw. and Commiphora myrrha (Nees) Engl., commonly known as frankincense and true myrrh respectively, have been used extensively since 2800 BCE for the treatment of skin sores, wounds, teeth, inflammation, and urinary tract diseases in traditional medicine; for preparation of mummification balms and unguents; and also as incense and perfumes. Since ancient times, burning of frankincense and myrrh in places of worship for spiritual purposes and contemplation (a ubiquitous practice across various religions) had hygienic functions, to refine the smell and reduce contagion by purifying the indoor air. Aim of the study: The general purpose of the study was to assess the in vitro antimicrobial potential of the liquid and vapour phases of B. carteri and C. myrrha essential oils and burn incense, as well as to test the effectiveness of their in situ application to cleanse microbially-contaminated air within the ambient of an investigated 17th century church. Materials and methods: The chemical composition of B. carteri and C. myrrha essential oils, obtained by hydro distillation of frankincense and true myrrh oleo gum resins was determined using GC/MS, and antimicrobial properties of their liquid and vapour phases were assessed by the broth microdilution and microatmosphere diffusion methods. Chemical analysis of burn incense fume obtained using bottle gas washing with dichloromethane as a solvent was performed by GC/MS, while its antimicrobial activity was evaluated using a modified microatmosphere diffusion method to evaluate germination inhibition for fungi and CFU count reduction for bacteria. The in situ antimicrobial activity of B. carteri burn incense and essential oil vapour phase was assessed in the sealed nave and diaconicon of the church, respectively. Results: The dominant compounds of B. carteri EO were a-pinene (38.41%) and myrcene (15.21%), while C. myrrha EO was characterized by high content of furanoeudesma-1,3-diene (17.65%), followed by curzerene (12.97%), f3-elemene (12.70%), and germacrene B (12.15%). Burn incense fume and soot had a-pinene (68.6%) and incensole (28.6%) as the most dominant compounds, respectively. In vitro antimicrobial assays demonstrated high bacterial and fungal sensitivity to the liquid and vapour phases of Eos, and burn incense fume. In situ application of B. carteri EO vapour and incense fume resulted in reduction of air -borne viable microbial counts by up to 45.39 +/- 2.83% for fungi and 67.56 +/- 3.12% for bacteria (EO); and by up to 80.43 +/- 2.07% for fungi and 91.43 +/- 1.26% for bacteria (incense fume). Conclusions: The antimicrobial properties of essential oil derived from frankincense, a compound with wellknown traditional use, showed that it possesses a clear potential as a natural antimicrobial agent. Moreover, the results suggest possible application of B. carteri EO vapour and incense fume as occasional air purifiers in sacral ambients, apart from daily church rituals.

abstract = "Ethnopharmacological relevance: Essential oils obtained from resins of Boswellia carteri Birdw. and Commiphora myrrha (Nees) Engl., commonly known as frankincense and true myrrh respectively, have been used extensively since 2800 BCE for the treatment of skin sores, wounds, teeth, inflammation, and urinary tract diseases in traditional medicine; for preparation of mummification balms and unguents; and also as incense and perfumes. Since ancient times, burning of frankincense and myrrh in places of worship for spiritual purposes and contemplation (a ubiquitous practice across various religions) had hygienic functions, to refine the smell and reduce contagion by purifying the indoor air. Aim of the study: The general purpose of the study was to assess the in vitro antimicrobial potential of the liquid and vapour phases of B. carteri and C. myrrha essential oils and burn incense, as well as to test the effectiveness of their in situ application to cleanse microbially-contaminated air within the ambient of an investigated 17th century church. Materials and methods: The chemical composition of B. carteri and C. myrrha essential oils, obtained by hydro distillation of frankincense and true myrrh oleo gum resins was determined using GC/MS, and antimicrobial properties of their liquid and vapour phases were assessed by the broth microdilution and microatmosphere diffusion methods. Chemical analysis of burn incense fume obtained using bottle gas washing with dichloromethane as a solvent was performed by GC/MS, while its antimicrobial activity was evaluated using a modified microatmosphere diffusion method to evaluate germination inhibition for fungi and CFU count reduction for bacteria. The in situ antimicrobial activity of B. carteri burn incense and essential oil vapour phase was assessed in the sealed nave and diaconicon of the church, respectively. Results: The dominant compounds of B. carteri EO were a-pinene (38.41%) and myrcene (15.21%), while C. myrrha EO was characterized by high content of furanoeudesma-1,3-diene (17.65%), followed by curzerene (12.97%), f3-elemene (12.70%), and germacrene B (12.15%). Burn incense fume and soot had a-pinene (68.6%) and incensole (28.6%) as the most dominant compounds, respectively. In vitro antimicrobial assays demonstrated high bacterial and fungal sensitivity to the liquid and vapour phases of Eos, and burn incense fume. In situ application of B. carteri EO vapour and incense fume resulted in reduction of air -borne viable microbial counts by up to 45.39 +/- 2.83% for fungi and 67.56 +/- 3.12% for bacteria (EO); and by up to 80.43 +/- 2.07% for fungi and 91.43 +/- 1.26% for bacteria (incense fume). Conclusions: The antimicrobial properties of essential oil derived from frankincense, a compound with wellknown traditional use, showed that it possesses a clear potential as a natural antimicrobial agent. Moreover, the results suggest possible application of B. carteri EO vapour and incense fume as occasional air purifiers in sacral ambients, apart from daily church rituals.",

AB  - In the light of growing interest in discovering new sources of natural antimicrobial agents, we extracted and tested the efficiency of julid defensive secretions in comparison with commercially used antibiotic and antimycotics. This work involved chemical characterization of the defensive secretions of Cylindroiulus boleti (C. L. Koch, 1847), Megaphyllum bosniense (Verhoeff, 1897) and M.unilineatum (C. L. Koch, 1838), as well as in vitro evaluation of their antimicrobial activity against 11 bacteria, one yeast and eight filamentous fungi. Compounds of the analysed defensive secretions included p-benzoquinones, alkyl esters of fatty acids and ketones. Ketones were recorded for the first time in the order Julida, and they were detected in secretions of both Megaphyllum species. All three analysed defensive secretions showed antibacterial and antifungal potential against all of the tested pathogens. Staphylococcus aureus proved to be the most sensitive bacterial strain to all analysed secretions. Also, defensive secretion of M.unilineatum showed significant antibacterial potential against Bacillus subtilis. The most resistant bacterial strains in this study were Escherichia coli, Erwinia persicina and Pseudomonas syringae pv. tomato. Analysed defensive secretions achieved the strongest antifungal activity against Aspergillus parasiticus (secretions of all three millipede species), Penicillium griseofulvum (secretions of C.boleti and M.bosniense) and Cladosporium oxysporum (secretion of M.unilineatum). The most resistant mycromycetes were A.niger (to all tested defensive secretions), A.flavus (to secretion of M.unilineatum) and P.lanosum (to secretions of C.boleti and M.bosniense). Our results showed a generally lower level of activity compared to antibiotic and a significantly higher level compared to antimycotics. The results of this study elucidate and open opportunities for further research in the field of millipede chemical ecology.

AB  - Comprehensive analysis of phenolic profiles of botanically different subtypes of Turkish propolis samples were performed using UHPLC-LTQ/Orbitrap/MS/MS method, and additionally total phenolic (TPC) and total flavonoid contents (TFC) as well as their antioxidative activities were evaluated by spectrophotometry. Antimicrobial activity of Turkish propolis against oral cavity bacteria from the genus Streptococcus (S. pyogenes, S. sanguinis, S. mutans) and Candida albicans ATCC 10231 was determined by diffusion and microdilution methods. Extensive fingerprint analysis of Turkish propolis revealed the presence of fifty one phenolic compounds, with fifteen quantified which confirm their affiliation to the two subtypes of the European propolis. All analysed samples have shown antimicrobial potential against all tested bacteria, with S. pyogenes being the most sensitive one. Turkish propolis, especially its orange subtype, can be considered as the high-quality product due to its rich phenolic and flavonoid content, strong antioxidative and antimicrobial activities. Turkish propolis could be, therefore, a good raw material for food and pharmaceutical industry.

AB  - Comprehensive analysis of phenolic profiles of botanically different subtypes of Turkish propolis samples were performed using UHPLC-LTQ/Orbitrap/MS/MS method, and additionally total phenolic (TPC) and total flavonoid contents (TFC) as well as their antioxidative activities were evaluated by spectrophotometry. Antimicrobial activity of Turkish propolis against oral cavity bacteria from the genus Streptococcus (S. pyogenes, S. sanguinis, S. mutans) and Candida albicans ATCC 10231 was determined by diffusion and microdilution methods. Extensive fingerprint analysis of Turkish propolis revealed the presence of fifty one phenolic compounds, with fifteen quantified which confirm their affiliation to the two subtypes of the European propolis. All analysed samples have shown antimicrobial potential against all tested bacteria, with S. pyogenes being the most sensitive one. Turkish propolis, especially its orange subtype, can be considered as the high-quality product due to its rich phenolic and flavonoid content, strong antioxidative and antimicrobial activities. Turkish propolis could be, therefore, a good raw material for food and pharmaceutical industry.

AB  - In this study the efficacy of two different methods for extracting lipopeptides produced by five Bacillus strains-ethyl acetate extraction, and acid precipitation followed by methanol extraction-was investigated using mass spectrometry. High performance thin layer chromatography (HPTLC) was also used for the simultaneous separation of complex mixtures of lipopeptide extracts and for the determination of antimicrobial activity of their components. The mass spectra clearly showed well-resolved groups of peaks corresponding to different lipopeptide families (kurstakins, iturins, surfactins, and fengycins). The ethyl acetate extracts produced the most favorable results. The extracts of SS-12.6, SS-13.1, and SS-38.4 showed the highest inhibition zones. An iturin analog is responsible for the inhibition of Xanthomonas arboricola and Pseudomonas syringae phytopathogenic strains. HPTLC bioautography effectively identified the active compounds from a mixture of lipopeptide extracts, proving in situ its potential for use in direct detection and determination of antimicrobials. In the test of potential synergism among individual extracts used in different mixtures, stronger antimicrobial effects were not observed. Biochemical and phylogenetic analysis clustered isolates SS-12.6, SS-13.1, SS-27.2, and SS-38.4 together with Bacillus amyloliquefaciens, while SS-10.7 was more closely related to Bacillus pumilus.

AB  - The chemical defence of the millipede Pachyiulus hungaricus is reported in the present paper, in which a chemical characterization is given and antimicrobial activity is determined. In total, independently of sex, 44 compounds were identified. All compounds belong to two groups: quinones and pentyl and hexyl esters of long-chain fatty acids. The relative abundances of quinones and non-quinones were 94.7% vs. 5.3% (males) and 87.3% vs. 12.7% (females), respectively. The two dominant quinones in both sexes were 2-methyl-1,4,-benzoquinone and 2-methoxy-3-methyl-1,4-benzoquinone. Antibacterial and antifungal activity of the defensive secretion was evaluated in vitro against seven bacterial strains and eight fungal species. With the aid of a dilution technique, the antimicrobial potential of the secretion and high sensitivity of all tested strains were confirmed. The lowest minimum concentrations of these compounds (0.20-0.25 mg/mL) were sufficient for inhibition of Aeromonas hydrophila, Listeria monocytogenes and Methicillin resistant Staphylococcus aureus (MRSA). The growth of eight tested fungal species was inhibited by slightly lower concentrations of the secretion, with Fusarium equisetias the most sensitive fungus and Aspergillus flavus as the most resistant. Values of MIC and MFC in the employed microdilution assay ranged from 0.10 to above 0.35 mg/m L. The given extract contains antimicrobial components potentially useful as therapeutic agents in the pharmaceutical and agricultural industries.
