AB  - Among numerous available nanomaterials, nanoceria (NC) has a particular importance based on its redox properties which are considered as a cause of antibacterial activity [1]. Pseudomonas aeruginosa is Gram-negative bacteria, well known for its ability to grow in diverse environments due to great potential for adaptation and its metabolic diversity. Its ability to overcome the challenges lies on bacterial cell-cell communication mechanism, known as quorum sensing (QS) system, which regulates expression of numerous genes [2]. To reveal effects of NC on metabolism of environmental isolate of polyextremophile P. aeruginosa san ai, production of exopolysaccharide, pigment – pyocyanin, siderophores – pyoverdine and pyochelin, as well accompanied changes related to QS, biofilm formation, and redox homeostasis were investigated. The minimal inhibitory concentration of NC against P. aeruginosa san ai is 8 mg/mL, which classifies it in a group of highly resistant Pseudomonas. P. aeruginosa san ai exhibited an important formation of biofilm, with OD590 readings of 0.21 for culture grown in LB and in range from 0.26 to 0.57 for culture from LB amended with increasing concentrations of NC (from 0.5 to 5 mg/mL). Accordingly, P. aeruginosa san ai can be classified as moderately adherent strain. Changes in alginate formation with increasement of 37% in the presence of NC, which have been detected, imply its engagement in the cell protection. An improved biofilm formation and production of alginate in the culture exposed to nanoceria clearly indicates their role in the first line of defence, according to previous data [3]. The up-regulation of both siderophores pyoverdine and pyocheline, was detected in cultures amended with NC, suggesting strong effect of NC on the iron homeostasis. The siderophore biosynthesis and transport require tight regulation, particularly in case of exposure to the toxic threat of ROS generated. Free radical species can trigger Fenton reaction further compromising the maintenance of intracellular iron levels. An improved production of pyoverdine- highly iron-specific siderophore, obtained in this study clearly documents how promptly and efficiently the bacteria reacts to overcome exhaustion of iron. Production of pyocyanin is almost 3 times higher in nanoceria amended culture than in control, clearly suggesting redox homeostasis disturbance caused by NC. Although NADH/NAD redox couple plays a major role in central metabolism of P. aeruginosa, another characteristic feature of P. aeruginosa is the ability to produce redox-active pyocyanin, which can react with NADH suggesting that electron transfer to pyocyanin may represent an adaptation that allows bacteria to modulate their intracellular redox state.

AB  - Environmental pollution with petroleum and petrochemical products has attracted much attention in recent years. The present study is focused on the investigation of urban soil pollution in the area of thermal plant New Belgrade with more than 200000 residents. Thermal Power Plant New Belgrade is located on the left bank of the Sava, about 1 km from the Sava’s confluence with the Danube. The Thermal Power Plant complex consists of storage tanks for crude oil and oil products and it was contaminated due to break-down of the mazut reservoirs (2009, during a gas crisis) and NATO bombing of the reservoirs (1999). A total of 45 soil samples were collected in May, 2015, and in total 8 geochemical parameters were determined by using official or recommended methods [1]. Statistical data processing includes application of multivariate statistical methods to previously systematized data on geochemical parameters in soil samples from Belgrade city. Two multivariate statistical methods have been applied – hierarchical cluster analysis (HCA) and factor analysis – analysis of the main components (PCA). From the output of the hierarchical cluster analysis, a total of three clusters of the soil samples were recognized according to the level of clustering. Cluster A and B are linked at a shorter distance and are together linked to Cluster C at a longer distance. Component 1 of the PCA dominated in group A. Samples of group A contained the maximum amounts of total aliphatic hydrocarbon (TPH) (71.85±17.9), and Unresolved/Resolved complex mixture (U/R) (3.02±1.8) higher than the other groups. The results of the soil analyses indicated that most samples classified as C1 may reflect anthropogenic contamination of the urban environment. The results showed that the top soil contained high concentration of TPH (90.65 mg kg−1). This may be a result was caused by crude oil spills and leaks which continuously occured for long periods of time. According to the “Regulation on the program of systematic monitoring of land quality, indicators for According to the “Regulation on the program of systematic monitoring of land quality, indicators for assessment of the risk of land degradation and the methodology for making remediation programs “(Official Gazette of RS, No. 88/2010-Annex 13) are not higher than” values that may indicate significant contamination “-remediation values, but are higher than ”limit values“, which means that this area must be programs “(Official Gazette of RS, No. 88/2010-Annex 13)) are not higher than” values that may indicate significant contamination “-remediation values, but are higher than” limit values “, which means that this area must be under permanently monitoring. Group B is represented by a principal component 2 related to the highest CPI (3.48±1.32), Low/High alkanes (0.299±0.45), and ACL (the average number of carbon atoms per molecule based on the abundance of odd-carbon-numbered higher plant n-alkanes) (29.67±0.40). The analyzed samples have similar ACL contents in all groups. Distribution of these parameters suggesting predominant biogenic sources rather than petroleum related input. The component 3 of the PCA2, loaded by n-C17/ Pr, and n-C18/Phy, also constituted a strong cluster C, n-C17 and n-C18 are more abundant than the isoprenoids pristane and phytane. Comparatively, isoprenoid hydrocarbons are more resistant to biodegradation than n-alkanes [2], leading to the increase of Pr/ n-C17 and Ph/n-C18 ratios to a value of much higher than 1 when they have been deeply degraded [3]. The distribution of Pr/n-C17, and Ph/n-C18 ratios for almost all samples are small than 1, indicate biogenic contribution, except of some samples are around 1, points to petroleum contamination source in urban area of Belgrade city.

AB  - Due to their extensive use, petroleum hydrocarbons are among the most common groundwater contaminants. Compared to the traditional methods of physical pumping of contamination from the aquifer and subsequent treatment (i.e., pump and treat), bioremediation is an economically cost-effective technology. The aim of this remediation approach is to transform biologically contaminants, most often by microbiological activity, into non-toxic compounds. More precisely, it is an active remediation process that involves biostimulation (increase of aquifer oxygenation, addition of nutrients) and/or bioaugmentation (injection of a concentrated and specialized population of microorganisms). Using both biostimulation and bioaugmentation, enhanced in situ groundwater bioremediation was applied at a hydrocarbon-contaminated site in Belgrade. The bioremediation treatment, applied over twelve months, was highly efficient in reducing the concentrations of total petroleum hydrocarbon (TPH) to acceptable levels. The concentration of TPH in the piezometer P-5 was reduced by 98.55 %, in the piezometer P-6 by 98.30 % and in the piezometer P-7 by 98.09 %. These results provided strong evidence on the potential of this remediation approach to overcome site-limiting factors and enhance microbiological activity in order to reduce groundwater contamination.

After covalent modification of polysaccharides by cholesterol, noncovalent hybrids were prepared by a three-step procedure, including mixing of individual aqueous solutions of hydrophobized, as well as native sugar with solution of the fullerene in pyridine, dialysis and lyophilization. Although the degree of the fullerene incorporation into hydrophobized substrates, cholesterol-levan and cholesterol-pullulan, was lower in comparison to the native polysaccharide levan, hydrophobization provided nanoparticles with improved properties. The particle size distribution, studied by dynamic light scattering and scanning electron microscopy revealed formation of moderately polydisperse aggregates, with the diameter contraction in comparison to the corresponding free polysaccharide, especially in the case of hydrophobized substrates. The morphological examination, done by scanning electron microscopy indicated the self-organization of the fullerene-native polysaccharide to round individual structures, while fullerene-hydrophobized polysaccharide hybrids tend to form networks. The antioxidant activity of the synthesized polysaccharide-C60 noncovalent hybrids versus starting polysaccharides was investigated by the DPPH radical scavenging and the β-carotene-linoleic acid bleaching methods. In all three complexes, the radical scavenging ability of the fullerene remained preserved, and a positive effect of levan hydrophobization was observed.

abstract = "An efficient encapsulation of the fullerene into two hydrophobized and one native polysaccharide provided water soluble supramolecular hybrids. After covalent modification of polysaccharides by cholesterol, noncovalent hybrids were prepared by a three-step procedure, including mixing of individual aqueous solutions of hydrophobized, as well as native sugar with solution of the fullerene in pyridine, dialysis and lyophilization. Although the degree of the fullerene incorporation into hydrophobized substrates, cholesterol-levan and cholesterol-pullulan, was lower in comparison to the native polysaccharide levan, hydrophobization provided nanoparticles with improved properties. The particle size distribution, studied by dynamic light scattering and scanning electron microscopy revealed formation of moderately polydisperse aggregates, with the diameter contraction in comparison to the corresponding free polysaccharide, especially in the case of hydrophobized substrates. The morphological examination, done by scanning electron microscopy indicated the self-organization of the fullerene-native polysaccharide to round individual structures, while fullerene-hydrophobized polysaccharide hybrids tend to form networks. The antioxidant activity of the synthesized polysaccharide-C60 noncovalent hybrids versus starting polysaccharides was investigated by the DPPH radical scavenging and the β-carotene-linoleic acid bleaching methods. In all three complexes, the radical scavenging ability of the fullerene remained preserved, and a positive effect of levan hydrophobization was observed.",

AB  - The plants from genus Salvia, as one of the largest genus in Lamiaceae family, are frequently in use for various purposes, as foods, in cosmetic industry, or in traditional and official medicine. Salvia verticillata L. (liliac sage) is one of sidelined sage species with potential bioactivity, reported in traditional medicine. The aim of this study was to acquire a phytochemical profile of the methanol extract obtained from S. verticillata aerial parts and to evaluate its antioxidant, antimicrobial, and biocompatibility potential. Characteristic compounds of the genus Salvia, such as rosmarinic and caffeic acids, along with their derivatives (e.g. salvianolic and yunnaneic acids isomers) and flavonoids, have been identified by ultrahigh-performance Orbitrap metabolomic fingerprinting as the main phenolic metabolites in S. verticillata. The extract displayed moderate antimicrobial properties and significant antioxidant potential, with the half maximal inhibitory concentration values (IC50) ranging from 33 to 73 μg/mL. Importantly, full biocompatibility of the extract with eukaryotic cell lines was observed up to 72 h. The obtained results revealed the presence of polyphenolic bioactive compounds in S. verticillata extract with promising antioxidant potential and significant biocompatibility. In this regard, S. verticillata can find new perspectives of application as a food ingredient, in cosmetic and pharmaceutical industries, as it represents a valuable source of compounds with prominent health properties, with a special focus on rosmarinic acid.

AB  - Concentrations of 10 potentially toxic trace elements were measured in soil samples collected from 18 sites in urban areas of Belgrade, the capital and the largest city in Serbia. Samples were analysed in order to assess the extent of soil contamination and to distinguish natural and anthropogenic input. The results demonstrated a general Zn, Pb, and Cd enrichment in surface samples, hence, after comparison with guidelines, it has been determined that there is a potential risk for human health. In the surface and buried samples, traces of cooper were detected. The highest concentrations of Cr (121 ± 12.3 mg/kg) and Ni (94.9 ± 12.6 mg/kg) were found at a sediment depth of 2 m and should be ascribed to geogenic sources. The results of HCA and PCA analysis supported a natural origin of Co, Cu, Mn, Cr, and Ni, while Cd, Zn, and Pb originated from anthropogenic inputs. Based on the pollution indices, Cd made the most dominant contribution, posing a high contamination risk in the studied area. Results of Nemerow pollution index (PIN) and potential ecological risk index (PER) demonstrated that pollution by heavy metals in sediments on several sites is moderately intense.

AB  - Environmental pollution is a global problem, while bioremediation technology removes pollutants from the environment using microorganisms. This study was aimed at investigating how a bioremediation process affected soil humification. In soil polluted with petroleum and its derivatives that was submitted to bioremediation, besides the total petroleum hydrocarbons and the number of microorganisms, quantitative and qualitative changes of isolated humic acids were determined during the process. The bioremediation of 150 m3 of polluted soil lasted 150 days. The level of total petroleum hydrocarbons decreased by 86.6 %, while the level of humic acids increased by 26.5 %. The elemental analysis showed the reduction of C and the H/C ratio and the increase of O and the O/C ratio of isolated humic acids during the process. The ratio of absorbencies at 465 and 665 nm also increased. Based on this and the Fourier-transform infrared spectra, it was shown that the humic acids isolated at the end of bioremediation were enriched with oxygen functional groups and aromatic structures. This study provides one of the first insights into the relationship between bioremediation and humification, as well as evidence of how hydrocarbon-degrading microorganisms have a significant influence on changes to humic acid structure during bioremediation.

AB  - Pseudomonas aeruginosa san ai, an alkaliphilic, metallotolerant bacterium, degraded individual selected petroleum compounds, i.e., n-alkanes (n-hexadecane, n-nonadecane) and polycyclic aromatic hydrocarbons (fluorene, phenanthrene, pyrene) with efficiency of 80%, 98%, 96%, 50% and 41%, respectively, at initial concentrations of 20 mg L−1 and in seven days. P. aeruginosa san ai showed a high biodegradative capacity on complex hydrocarbon mixtures, the aliphatic and aromatic fractions from crude oil. The efficiency of P. aeruginosa san ai degradation of crude oil fractions in seven days reached stage 3–4 of the oil biodegradation scale, which ranges from 0 (no biodegradation) to 10 (maximum biodegradation). Identified metabolites concomitant with genomic and enzymatic data indicated the terminal oxidation pathway for the n-alkane degradation, and the salicylate and phthalate pathways for fluorene biodegradation. Polyextremophilic P. aeruginosa san ai, as a biosurfactant producer with multidegradative capacity for hydrocarbons, can be used in an improved strategy for environmental bioremediation of hydrocarbon-contaminated sites, including extreme habitats characterized by low or elevated temperatures, acidic or alkaline pH or high concentrations of heavy metals.

Identified metabolites concomitant with genomic and enzymatic data indicated the terminal oxidation pathway for the n-alkane degradation, and the salicylate and phthalate pathways for fluorene biodegradation. Polyextremophilic P. aeruginosa san ai, as a biosurfactant producer with multidegradative capacity for hydrocarbons, can be used in an improved strategy for environmental bioremediation of hydrocarbon-contaminated sites, including extreme habitats characterized by low or elevated temperatures, acidic or alkaline pH or high concentrations of heavy metals.",

AB  - Aquifer contamination by petroleum hydrocarbons leads to measurable changes of groundwater hydrochemistry, primarily due to the microbiological activity. This study analyzes this phenomenon at an historical kerosene-contaminated site in Vitanovac (central Serbia). Due to the long-term hydrocarbon contamination and exposure to aerobic and anaerobic biodegradation mechanisms, the lowest concentrations of O2, NO3−, and SO42− (electron acceptors) and the highest concentrations of Mn and Fe (products of microbial metabolic activity) overlap. The terminal redox-accepting processes in groundwater ranged from oxygen reduction to sulfate reduction. The most anoxic processes were registered in piezometers closest to the source of contamination, as was also confirmed by the redox potential (Eh) measurements. High electrical conductivity values and the highest TOC, SiO2, and Al concentrations also overlap in the contaminated zone close to the source of contamination. Scanning electron microscopy study of quartz grains from the zone undergoing the impact of biodegradation confirmed the occurrence of weathering microscale processes on mineral surfaces. Taking all these factors together, it seems reasonable to assume that microbiological activity has caused the enhanced weathering of silicate minerals.

AB  - Reports about the influence of cerium-oxide nanoparticles (nCeO2) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO2 with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO2 were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO2 on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL-1 of nCeO2 on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO2 was studied by measuring changes in Ce concentration, total antioxidative activity (TAA), total phenolic content (TPC), and phenolic profile. Our results generally revealed higher Ce concentration in plants after the treatment with coated nanoparticles compared to uncoated ones. Considering all obtained results, Ger treatment had a stronger impact on the later stages of plant development than Gro treatment. The Ger treatment had a stronger impact on TPC and plant elongation, whereas Gro treatment affected more TAA and phenolic profile. Among nanoparticles, levan-coated nCeO2 had the strongest and positive impact on tested plants. Wheat showed higher sensitivity to all treatments.

Najviši prinosipolisaharida se dobijaju na temperaturi od 37 °C i bez mešanja. Upotrebom podloge sa196,75 g/L saharoze, 2,44 g/L amonijum-hlorida i inicijalnog pH od 6,97 dobija se 47,84g/L levana LS200, a na podlozi sa 397,65 g/L saharoze, 4,62 g/L amonijum-hlorida iinicijalnog pH od 7,31 dobija se 99,19 g/L levana LS400. U sledećim uslovima: 62,6 %melase, 4,66 g/L fosfata i inicijalnim pH od 7,2 dobija se 53,6 g/L levana LM.Strukturna ispitivanja (kisela hidroliza, metilaciona analiza, FTIR, 13C- i 1H-NMR,COSY, HSQC i HMBC) su pokazala da su dobijeni levani polifruktani sa β-(2,6)-glikozidnom vezom u osnovnom nizu i grananjem u položaju β-(2,1). Stepeni grananja su11,04 ± 0,57 %, 11,99 ± 0,63 % 12,68 ± 0,71 % za levane LS200, LS400 i LMrespektivno. Levani LS200 i LM relativno su visoke molekulske mase (opseg > 106 Da) saviskozitetima 0,25 dL/g i 0,24 dL/g, dok je levan LS400 niže molekulske mase (105 Da) iviskoziteta 0,14 dL/g.U poslednjoj seriji eksperimenata ispitivan je uticaj različitih reakcionih uslova nasintezu Lev-g-PS slobodnoradikalskim mehanizmom i upotrebom kalijum-persulfata kaoinicijatora. Maksimalni G (%) = 58,1 dobijen je na 70 °C, u atmosferi azota i upotrebomaminoaktivatora DMEA. FTIR, SEM, TG/DTA, XRD i 13C NMR spektroskopija dobijenogkopolimera su pokazali da je došlo do reakcije kalemljenja između levana i polistirena.
AB  - Within this doctoral dissertation, the effects of various fermentation factors on levanproduction by Bacillus lichenifomis NS032 were studied, structure of obtainedpolysaccharide was investigated and grafted copolymers of levan and polystyrene (Lev-g-PS) were synthetized.In the first series of experiments, media for levan production were optimized usingone factor at a time and response surface methods. The highest levan yield was obtained at37 °C and without agitation. Using the medium with 196.75 g/L sucrose, 2.44 g/Lammonium chloride and pH 6.97, obtained amount of LS200 levan was 47.84 g/L and inmedium with 397.65 g/L sucrose, 4.62 g/L ammonium chloride and pH 7.31 amount ofLS400 levan was 99.19 g/L. In the following conditions: 62.6 % molasses, 4.66 g/Lphosphate and an initial pH 7.2, LM levan (53.6 g/L) was obtained.Structural characterization (acid hydrolisis, methylation analysis, FTIR, 13C- and1H-NMR, COSY, HSQC i HMBC) showed that investigated levans are polyfructans with β-(2,6)- glycosidic linkages in backbone and branching through β-(2,1) positions. The extentsof branching are 11.04 ± 0.57 %, 11.99 ± 0.63 % 12.68 ± 0.71 % for LS200, LS400 andLM levans, respectively. LS200 and LM have relatively high molecular weight (range >106 Da) and viscosity (0.25 dL/g and 0.24 dL/g), contrary to LS400 with lower molecularweight (105 Da) and viscosity (0.14 dL/g).Finally, influence of different reaction conditions on synthesis of Lev-g-PS by freeradical mechanism and potassium persulfate as initiator was investigated. Maximum G (%)= 58.1 was obtained at 70 °C, in nitrogen atmosphere and using the amine activator DMEA.FTIR, SEM, TG/DTA, XRD and 13C NMR spectroscopy of copolymer showed thatgrafting reaction of levan and polystyrene was successful.

AB  - The analysis of the electric, magnetic and electromagnetic fields influence on microorganisms is a very popular research topic, since these fields could potentially act as stressors and affect the microbial metabolism and survival. The aim of this work was to investigate the influence of the low frequency magnetic field (MF) with scan regime from 10 Hz to 50 Hz on S. cerevisiae respiration. The experiment was performed in five replicates and monitored using the Micro-Oxymax® respirometer. All five experiments showed lower cumulative O2 consumption in MF exposed samples, compared to the control sample and inconsistent cumulative CO2 production. However, these differences in O2 consumption and CO2 production were statistically significant. Even though additional experiments are necessary, these results strongly suggest that this is a good basis for further investigation in this field.

Eksperiment je rađen u pet ponavljanja i praćen Micro-Oxymax® respirometrom. Kumulativna potrošnja kiseonika je bila manja kod ćelija izloženih MP u svih pet ponavljanja, dok je produkcija CO2 bila nekonzistentna. Međutim, ove razlike u potrošnji O2 i produkciji CO2 su statistički značajne. Iako su dodatna ispitivanja neophodna, dobijeni rezultati ovih inicijalnih eksperimenata predstavljaju dobru osnovu za dalja istraživanja u ovoj oblasti.

AB  - The Pseudomonas aeruginosa san ai strain was investigated for its capability to degrade the 2,6-di-tert-butylphenol (2,6-DTBP) plastic additive, a hazardous and toxic substance for aquatic life. This investigation was performed under different parameter values: 2,6-DTBP concentration, inoculum size, pH, and temperature. The GC-MS study showed that P. aeruginosa efficiently degraded 2,6-DTBP in the pH range of 5-8 at higher temperatures. Under exposure to 2,6-DTBP concentrations of 2, 10, and 100 mg L-1, the strain degraded by 100, 100, and 85%, respectively, for 7 days. Crude enzyme preparation from the biomass of P. aeruginosa san ai showed higher efficiency in 2,6-DTBP removal than that shown by whole microbial cells. Gene encoding for the enzymes involved in the degradation of aromatic compounds in P. aeruginosa san ai was identified. To complement the genomic data, a comparative proteomic study of P. aeruginosa san ai grown on 2,6-DTBP or sunflower oil was conducted by means of nanoLC-MS/MS. The presence of aromatic substances resulted in the upregulation of aromatic ring cleavage enzymes, whose activity was confirmed by enzymatic tests; therefore, it could be concluded that 2,6-DTBP might be degraded by ortho-ring cleavage. A comparative proteomics study of P. aeruginosa san ai indicated that the core molecular responses to aromatic substances can be summarized as the upregulation of proteins responsible for amino acid metabolism with emphasized glutamate metabolism and energy production with upregulated enzymes of glyoxylate bypass. P. aeruginosa san ai has a high capacity to efficiently degrade aromatic compounds, and therefore its whole cells or enzymes could be used in the treatment of contaminated areas.

AB  - The influence of four low-frequency magnetic field (MF) ranges 10–300 Hz, 10–100 Hz, 10–50 Hz and 50–100 Hz in scanning regime (all frequencies from selected range were scanned during 100 s repetitively during 24 h) on baker's yeast cells Saccharomyces cerevisiae was examined by continuous measurements of cumulative O2 consumption and cumulative CO2 production over 24 h with Micro-Oxymax® respirometer. Besides respiration activity, measurements of cell growth and glucose uptake were performed as well. Statistical analysis indicated that, among all investigated low-frequency MF ranges, range from 10 Hz to 50 Hz had the greatest influence to yeast cell respiration and cell growth. More precisely, for this region, paired two sample one-tail t-test showed statistically significant differences in cumulative O2 consumption, cumulative CO2 production and S. cerevisiae cell number. Moreover samples exposed to MF range from 10 Hz to 50 Hz showed the same behavior in all five replicates: lower cumulative O2 consumption, higher cumulative CO2 production and higher cell number compared to control sample. This could be important from the application aspect, in industry (food, feed, brewery etc.) and biotechnology, because changes in cells metabolism are not caused by chemical treatment.

AB  - The influence of four low-frequency magnetic field (MF) ranges 10–300 Hz, 10–100 Hz, 10–50 Hz and 50–100 Hz in scanning regime (all frequencies from selected range were scanned during 100 s repetitively during 24 h) on baker's yeast cells Saccharomyces cerevisiae was examined by continuous measurements of cumulative O2 consumption and cumulative CO2 production over 24 h with Micro-Oxymax® respirometer. Besides respiration activity, measurements of cell growth and glucose uptake were performed as well. Statistical analysis indicated that, among all investigated low-frequency MF ranges, range from 10 Hz to 50 Hz had the greatest influence to yeast cell respiration and cell growth. More precisely, for this region, paired two sample one-tail t-test showed statistically significant differences in cumulative O2 consumption, cumulative CO2 production and S. cerevisiae cell number. Moreover samples exposed to MF range from 10 Hz to 50 Hz showed the same behavior in all five replicates: lower cumulative O2 consumption, higher cumulative CO2 production and higher cell number compared to control sample. This could be important from the application aspect, in industry (food, feed, brewery etc.) and biotechnology, because changes in cells metabolism are not caused by chemical treatment.

AB  - Microbial polysaccharides, due to their unique physiochemical properties, have found application in the food industry, cosmetics, pharmacy and medicine. In the environment, microbes can use polysaccharides to alleviate the adverse effects of heavy metals in their close proximity. This adaptive property shows interesting potential for bioremediation. Herein, the effects of the exopolysaccharides (EPS) levan, produced by the bacterium Bacillus licheniformis NS032 and pullulan, produced by the fungus Aureobasidium pullulans CH-1 in the presence of copper (Cu2+) have been investigated for the first time on antioxidant enzyme activity, respiration and Cu2+ bioaccumulation of Daphnia magna as well as the bioluminescence of Vibrio fischeri. Both EPS decreased toxicity of Cu2+ in the acute test with D. magna. The activity of catalase (CAT) was significantly diminished after acute exposure to Cu2+ in comparison to treatments with Cu2+ and EPS, while in the prolonged acute exposure the CAT activity did not show statistically significant (P ≤ 0.05) differences between treatments with and without the EPS. According to ICP-MS results, during prolonged acute exposure of neonates, the bioaccumulation of Cu2+ in treatments without the EPS was 52.03 μg/g of biomass (wet), while in treatments with EPS, the bioaccumulation was lower by one order of magnitude. The respiration of neonates during acute exposure to Cu2+ with or without the EPS was monitored using the MicroOxymax respirometer, and the results show the EPS can positively effect the respiration. In the case of bacterial bioluminescence, the toxicity of Cu2+ decreased in treatments with EPS (30 min EC10) from 3.54 mg/L to 140.61 mg/L (levan) and 45.00 mg/L (pullulan). This study demonstrates protective effect of EPS against Cu2+ toxicity on D. magna and V. fischeri, and opens the door for further investigation of potential application of levan and pullulan in bioremediation of heavy metals and mitigation of their adverse effects in the aquatic environment.
