AB  - Aquaphotomics is a relatively novel scientific discipline which can be used for elucidation of structural and  related functional properties of aqueous systems. The aim of this study was to analyse water solutions of carbohydrates of different size from monosaccharides (glucose and fructose) via, disaccharides (sucrose), gluco and fructo-oligosaccharides and various selected polisaccharides (based on glucose and fructose, respectively) using Aquaphotomics. Knowing that main functions of carbohydrates within our body are various: providing energy and regulation of blood glucose; sparing the use of proteins for energy; breakdown of fatty acids and preventing ketosis; biological recognition processes; flavor and sweeteners and dietary fibers who can promote digestive health, knowledge about their interaction with water molecules can have strong influence on our understanding of some basic but also complex metabolic processes.

AB  - 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 production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100–140 g/L of total sugars) with the addition of commercial sucrose up to 200 g/L of total sugars, as well as K2HPO4. A levan yield of 53.2 g/L was obtained on a medium optimized by response surface methodology, containing 62.6% of sugar originating from molasses, and 4.66 g/L of phosphate, with initial pH value of 7.2. In comparison to the media with 200 and 400 g/L sucrose, in the molasses optimized medium, the observed bacterial growth was faster, while the maximum production of polysaccharide was achieved over a shorter time interval (48 h). The polysaccharide produced in molasses medium had a weight average molecular weight of 5.82 × 106 Da, degree of branching 12.68%, viscosity of 0.24 dL/g, and based on methylation analysis and NMR data, it did not significantly differ from levan obtained in the medium with 200 g/L sucrose. © 2018 Elsevier B.V.

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.

AB  - The numerous naturally occurring biopolymeric materials are used as edible films and coatings (lipids, proteins, and polysaccharides). Microbial levan and pullulan have been already considered as biopolymers in food industry. The aim of this work was to obtain the levan and levan/pullulan blend films and compare them using the Atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR). Two different films compositions were prepared by casting method: levan and levan/pullulan in the proportions 1:1. AFM measurements showed that levan film had a smoother surface and, consequently, a lower degree of roughness comparing to the levan/pullulan blend films. FTIR spectra showed peaks, which corresponded to all components of the obtained films.

AB  - Vodeni organizmi su izloženi brojnim hemijskim supstancama različitih mehanizama toksičnosti i da bi se okarakterisali međusobni efekti važna je uporedna analiza hemijskih podataka i odgovarajućeg biološkog odgovora (biomarkeri) [1]. Slatkovodni, planktonski beskičmenjak Daphnia magna je dobro poznat model u ekotoksikologiji, zbog svoje visoke osetljivosti na toksične supstance i relativno lake kultivacije u laboratorijskim uslovima. Većina istraživanja o proceni toksičnosti različitih hemijskih supstanci bazira se na ispitivanju akutne toksičosti i letalne ili efektivne koncentracije supstance koje dovode do neželjenog efekta u 50 % slučajeva (LC50/EC50), međutim neophodne su i detaljnije informacije o toksičnosti, koje bi uključile subletalne efekte i senzitivnije biomerkere [2]. Pošto bakar i njegova jedinjenja spadaju u vodeće zagađujuće supstance vode, sprovedene su i evaluirane brojne procene njegovih opasnosti i/ili negativnih efekata (US EPA 2007;EU 2007) [3]. Homeostaza bakra u akvatičnim organizmima uključuje regulisan unos,transport i ekskreciju koja je slična kao kod sisara. Studije na D. magna, koje su bile izložene subletalnim koncentracijama bakra, pokazuju pojačan oksidativni stres u jedinkama [4]. U ovoj studiji praćena je potrošnja O2 i produkcija CO2 kod jedinki D. magna tokom48 h izlaganja Cu2+ jonima. Respiracija D. magna (MicroBioTests Inc.) neonata praćena je 48 h pomoću dvanaestokanalnog Micro-Oxymax respirometra (Columbus Instruments, SAD). U intervalima od 4 h merena je koncentracija O2, paramagnetnim senzorom, a CO2 infracrvenim senzorom, pri čemu je tokom celokupnog trajanja eksprerimenta sistem bio zatvoren. Uzorci su pripremani u providnim Micro-Oxymax bocama zapremine 500 mL u kojima je bilo po 100 mL tečne podloge i 20 neonata. Korišćen je AdaM medijum (Aachener Daphnien Medium) [5]. Koncentracija Cu2+ jona bila je 50 μg/mL i odabrana je prema literaturno određenoj EC50 vrednosti za CuSO4 [6]. Jedinke nisu hranjene tokom eksperimenta i izlagane su na temperaturi od 20±2 ºC i fotoperiodu 16 h dan/8 h noć. Dobijeni podaci su evaluirani Micro-Oxymax softverom i određena je kumulativna potrošnja/proizvodnja gasova (μL). Nakon izlaganja praćena je imobilizacija neonata, a rezultati su izraženi kao procenat mortaliteta. Dva dana nakon izlaganja D. magna sa Cu2+ jonima, zabeležen je mortalitet jedinki od 75 %. Test je bio validan, jer nije zabeležen mortalitet u kontrolnoj grupi. Kod organizama koji su bili izloženi jonima bakra kumulativna potrošnja O2 je znatno manja tokom celog eksperimenta, dok je kumulativna produkcija CO2 u prvih 24 h manja, a dalje razlike nisu uočene, što se može pripisati dekompoziciji imobilisanih jedinki. Na osnovu dobijenih rezultata zaključeno je da se test na MicroOxymax respirometru može koristiti kao dodatni parametar za procenu akutnih efekata toksičnih susptanci na organizam D. magna.

AB  - Cerium oxide (CeO2) nanoparticles (CONPs) are interesting biomaterials with various applications in biomedicine, cosmetics and the pharmaceutical industry, but with limited practical application because of their low stability in aqueous media. The aim of this study was to obtain CONPs with increased stability by coating the particles. Microbial exopolysaccharides (levan, pullulan) and glucose were used to prepare CONPs under different synthesis conditions. Coating was attempted by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of CONPs. The obtained nanoparticles were characterized by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The suspension stability of the uncoated and coated CONPs in aqueous media was evaluated by measuring the hydrodynamic size, zeta potential and turbidity. The FT-IR spectra revealed the differences between coated CONPs and showed the success of subsequent coating with carbohydrates. Coating with carbohydrates improved the stability the CONP suspension by decreasing the size of aggregated particles. The suspensions of levan- and glucose-coated CONPs had the best stability. In this study, CONPs were prepared using non-toxic materials, which were completely environmentally friendly. The obtained results open new horizons for CONP synthesis, improving their biological applications.

AB  - The aim of this work was structural characterization of EPS produced by Brachybacterium paraconglomeratum sp. CH-KOV3. For the structural instrumental analysis of EPS, the following methods were applied: GC-MS (gas chromatography mass spectrometry) and correlated two-dimensional NMR (nuclear magnetic resonance) techniques - DEPT 135 (distortionless enhancement by polarization transfer), COSY (correlation spectroscopy), and HSQC (heteronuclear single quantum coherence). Methylation was performed by the method which described earlier. The permethylated EPS was subjected to reductive cleavage as described by Rolf and Gray. Cleaved monomer units were acetylated. Obtained acetylated, methylated products were analyzed by GC-MS. These analyses were performed on a GCxGC-MS (Shimadzu, Kyoto, Japan). NMR spectra of the isolated EPS were measured on a Bruker AVANCE III 500 spectrometer.

AB  - Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role in protection of microbial cells under various external influences. For humans, these substances have potential use in many industries. EPSs can be applied as a flavor or a fragrance carrier, an emulsifier, a stabilizer, a prebiotic, an antioxidant or an antitumor agent. In this study, we characterized an environmental microorganism that produces EPS, optimized EPS production by this strain and characterized the EPS produced. Isolate CH-KOV3 was identified as Brachybacterium paraconglomeratum. The sucrose level in the growth medium greatly influenced EPS production, and the highest yield was when the microorganism was incubated in media with 500 g/L, of sucrose. The optimal temperature and pH were 28 degrees C and 7.0, respectively. The nuclear magnetic resonance (NMR) results and GC MS analysis confirmed that the residues were D-fructofuranosyl residues with beta-configuration, where fructose units are linked by beta-2,6-glycosidic bonds, with beta-2,1-linked branches. All these data indicate that the investigated EPS is a levan-type polysaccharide. Thus, it was concluded that Brachybacterium sp. CH-KOV3 could constitute a new source for production of the bioactive polysaccharide, levan. (C) 2017 Elsevier B.V. All rights reserved.
