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  - 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  - 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  - New information has come to light about the biological activity of propolis and the quality of natural products which requires a rapid and reliable assessment method such as High Performance Thin-Layer Chromatography (HPTLC) fingerprinting. This study investigates chromatographic and chemometric approaches for determining the antimicrobial activity of propolis of Serbian origin against various bacterial species. A linear multivariate calibration technique, using Partial Least Squares, was used to extract the relevant information from the chromatographic fingerprints, i.e. to indicate peaks which represent phenolic compounds that are potentially responsible for the antimicrobial capacity of the samples. In addition, direct bioautography was performed to localize the antibacterial activity on chromatograms. The biological activity of the propolis samples against various bacterial species was determined by a minimum inhibitory concentration assay, confirming their affiliation with the European poplar type of propolis and revealing the existence of two types (blue and orange) according to botanical origin. The strongest antibacterial activity was exhibited by sample 26 against Staphylococcus aureus, with a MIC value of 0.5 mg/mL, and Listeria monocytogenes, with a MIC as low as 0.1 mg/mL, which was also the lowest effective concentration observed in our study. Generally, the orange type of propolis shows higher antimicrobial activity compared to the blue type. PLS modelling was performed on the HPTLC data set and the resulting models might qualitatively indicate compounds that play an important role in the activity exhibited by the propolis samples. The most relevant peaks influencing the antimicrobial activity of propolis against all bacterial strains were phenolic compounds at RF values of 0.37, 0.40, 0.45, 0.51, 0.60 and 0.70. The knowledge gained through this study could be important for attributing the antimicrobial activity of propolis to specific chemical compounds, as well as the verification of HPTLC fingerprinting as a reliable method for the identification of compounds that are potentially responsible for antimicrobial activity. This is the first report on the activity of Serbian propolis as determined by several combined methods, including the modelling of antimicrobial activity by HPTLC fingerprinting.

abstract = "New information has come to light about the biological activity of propolis and the quality of natural products which requires a rapid and reliable assessment method such as High Performance Thin-Layer Chromatography (HPTLC) fingerprinting. This study investigates chromatographic and chemometric approaches for determining the antimicrobial activity of propolis of Serbian origin against various bacterial species. A linear multivariate calibration technique, using Partial Least Squares, was used to extract the relevant information from the chromatographic fingerprints, i.e. to indicate peaks which represent phenolic compounds that are potentially responsible for the antimicrobial capacity of the samples. In addition, direct bioautography was performed to localize the antibacterial activity on chromatograms. The biological activity of the propolis samples against various bacterial species was determined by a minimum inhibitory concentration assay, confirming their affiliation with the European poplar type of propolis and revealing the existence of two types (blue and orange) according to botanical origin. The strongest antibacterial activity was exhibited by sample 26 against Staphylococcus aureus, with a MIC value of 0.5 mg/mL, and Listeria monocytogenes, with a MIC as low as 0.1 mg/mL, which was also the lowest effective concentration observed in our study. Generally, the orange type of propolis shows higher antimicrobial activity compared to the blue type. PLS modelling was performed on the HPTLC data set and the resulting models might qualitatively indicate compounds that play an important role in the activity exhibited by the propolis samples. The most relevant peaks influencing the antimicrobial activity of propolis against all bacterial strains were phenolic compounds at RF values of 0.37, 0.40, 0.45, 0.51, 0.60 and 0.70. The knowledge gained through this study could be important for attributing the antimicrobial activity of propolis to specific chemical compounds, as well as the verification of HPTLC fingerprinting as a reliable method for the identification of compounds that are potentially responsible for antimicrobial activity. This is the first report on the activity of Serbian propolis as determined by several combined methods, including the modelling of antimicrobial activity by HPTLC fingerprinting.",

AB  - Extensive employment of plant resins and propolis, as an antiseptic agents dating from ancient times in numerous cultures indicating that it may have antimicrobial and other biological properties. Resins from deciduous trees from the Populus and Salix genera, several fruit trees from the genus Prunus and a few other species were analyzed for their phenolic composition and antibacterial activity. Phenolic profiling of the plant resins was performed by high-performance thin-layer chromatography (HPTLC) and ultra-high-performance liquid chromatography (UHPLC) coupled with hybrid mass spectrometry. Antimicrobial activity against seven bacterial species was determined by minimum inhibitory concentration (MIC) assays and bioautography. The synergism, additivism, and antagonism of phenolic compounds were used to define the nature and type of interactions. Populus spp. showed higher amounts of p-hydroxybenzoic acid, p-coumaric acid, caffeic acid, chrysin, apigenin, quercetin, pinocembrin, pinobanksin and galangin, which confirmed the botanical origin of the orange and blue types of propolis. In addition, Gram-positive bacteria exhibited high susceptibility to poplar samples while being resistant to samples from other origins. Cherry bud samples had high amounts of naringenin and showed strong activity against Bacillus subtilis and Listeria monocytogenes. The combinations of tested phenolics showed mainly additive or indifferent effects. (C) 2016 Elsevier B.V. All rights reserved.
