Аннотация: BACKGROUND The purpose of the present study was to develop ecofriendly herbicide formulations. Its main aim was to develop and investigate slow-release formulations of herbicides (metribuzin, tribenuron-methyl, and fenoxaprop-P-ethyl) of different structure, solubility, and specificity, which were loaded into a degradable matrix of poly-3-hydroxybutyrate (P(3HB)) blended with available natural materials (peat, clay, and wood flour). RESULTS Differences in the structure and physicochemical properties of the formulations were studied depending on the type of the matrix. Herbicide release and accumulation in soil were associated with the solubility of the herbicide. Fourier-transform infrared spectroscopy showed that no chemical bonds were formed between the components in the experimental formulations. Degradation of the formulations in agro-transformed soil in laboratory conditions was chiefly influenced by the shape of the specimens (granules or pellets) while the effect of the type of filler (peat, clay, or wood flour) was insignificant. The use of granules enabled more rapid accumulation of the herbicides in soil: their peak concentrations were reached after 3 weeks of incubation while the concentrations of the herbicides released from the pellets were the highest after 5-7 weeks. Loading of the herbicides into the polymer matrix composed of the slowly degraded P(3HB) and natural materials enabled both sustained function of the formulations in soil (lasting between 1.5 and >= 3 months) and stable activity of the otherwise rapidly inactivated herbicides such as tribenuron-methyl and fenoxaprop-P-ethyl. CONCLUSION The experimental herbicide formulations enabled slow release of the active ingredients to soil. (c) 2019 Society of Chemical Industry

Аннотация: To calculate the equivalent system mass of mushrooms, a conceptual configuration of a mushroom farm as part of a bioregenerative life support system on an inhabited lunar base was designed. The mushroom farm consists of two connected modules. Each module is a double-shell rigid pipe-in-pipe aluminum structure. The first module is used to prepare and sterilize the substrate, while the mushrooms are sown and grown in the second module. Planned productivity of the mushroom farm is 28 kg of fresh mushrooms per one process cycle lasting 66 days for 14 consumers. Mushroom production can be increased using additional modules. The calculated equivalent system masses of the mushroom farm and the mushrooms produced therein is 88,432 kg and 31,550 kg per 1 kg of dry mushrooms in one process cycle, respectively. At that, the biggest contributor to the equivalent system mass of mushrooms is the total pressurized volume of the farm - 68%. The results obtained may be a prerequisite for performing trade-off studies between different configurations of mushroom farm and calculating a space diet using the equivalent system mass of mushrooms.

Аннотация: The synthesis of bacterial cellulose (BC) by Komagataeibacter xylinus strain B-12068 was investigated on various C-substrates, under submerged conditions with stirring and in static surface cultures. We implemented the synthesis of BC on glycerol, glucose, beet molasses, sprat oil, and a mixture of glucose with sunflower oil. The most productive process was obtained during the production of inoculum in submerged culture and subsequent growth of large BC films (up to 0.2 m(2) and more) in a static surface culture. The highest productivity of the BC synthesis process was obtained with the growth of bacteria on molasses and glycerol, 1.20 and 1.45 g/L per day, respectively. We obtained BC composites with silver nanoparticles (BC/AgNPs) and antibacterial drugs (chlorhexidine, baneocin, cefotaxime, and doripenem), and investigated the structure, physicochemical, and mechanical properties of composites. The disc-diffusion method showed pronounced antibacterial activity of BC composites against E. coli ATCC 25922 and S. aureus ATCC 25923.

Аннотация: The study deals with the vertical distribution and seasonal dynamics of planktonic ciliates in the pelagic and littoral zones of a saline meromictic Lake Shira. Fourteen species of free-living ciliates have been found in the Lake, seven of them inhabiting the pelagic zone. The richness of ciliates is higher both in terms of the number of species and biomass in the littoral zone compared to the pelagic zone. Although the ciliate species diversity is low in the pelagic zone, in certain seasons, the biomass of some of the species may reach considerable values, up to 3.4 g m(-2) in the water column. The biomass of ciliates in Lake Shira is generally comparable to the average values for other mesotrophic lakes. The abundance and composition of ciliate populations in Lake Shira vary considerably with depth. Changes in the Lake ecosystem caused by meromixis breakdown in 2015-2016, which induced considerable variations in many Lake components, affected the vertical distribution of planktonic ciliates. However, the annual average biomass of the species that inhabited the Lake before meromixis breakdown remained unchanged. The total ciliate biomass increased due to the presence of the new species.

Аннотация: Active hydromedusan and ctenophore Ca2+-regulated photoproteins form complexes consisting of apoprotein and strongly non-covalently bound 2-hydroperoxycoelenterazine (an oxygenated intermediate of coelenterazine). Whereas the absorption maximum of hydromedusan photoproteins is at 460–470 nm, ctenophore photoproteins absorb at 437 nm. Finding out a physical reason for this blue shift is the main objective of this work, and, to achieve it, the whole structure of the protein–substrate complex was optimized using a linear scaling quantum–mechanical method. Electronic excitations pertinent to the spectra of the 2-hydroperoxy adduct of coelenterazine were simulated with time-dependent density functional theory. The dihedral angle of 60° of the 6-(p-hydroxy)-phenyl group relative to the imidazopyrazinone core of 2-hydroperoxycoelenterazine molecule was found to be the key factor determining the absorption of ctenophore photoproteins at 437 nm. The residues relevant to binding of the substrate and its adopting the particular rotation were also identified. © 2021, The Author(s), under exclusive licence to European Photochemistry Association,European Society for Photobiology.

Аннотация: The transfer pathways of organic matter and elements from phytoplankton to zooplankton in freshwater ecosystems are important for understanding how aquatic ecosystems function. We conducted a mesocosm experiment to determine how fish and zebra mussels altered the transfer efficiencies of essential substances including carbon (C), polyunsaturated fatty acids (PUFAs), total fatty acids (FAs), phosphorus (P), and nitrogen (N) from phytoplankton to zooplankton. We assessed the transfer efficiencies of the essential substances from phytoplankton to zooplankton as the ratio of their zooplankton production (P) per unit of biomass (B) to that of phytoplankton to exclude grazing or predation effects. We hypothesized that zebra mussels and fish would affect the transfer of materials from phytoplankton to zooplankton by altering the contents of essential elements and FAs in phytoplankton and zooplankton communities and/or due to shifts in the planktonic community structure mediated by grazing and/or predation. Fish increased the transfer efficiencies of eicosapentaenoic acid 20:5 omega-3 (EPA), docosahexaenoic acid 22:6 omega-3 (DHA), and P relative to the control. We speculated that fish weakened the control of zooplankton over algal assemblage by selectively feeding on larger cladocerans such as Daphnia. Therefore, fish can increase the relative proportion of high-quality food for zooplankton, improving food conditions for the available zooplankton. In contrast, zebra mussels reduced the transfer efficiencies of EPA and DHA relative to the control treatment likely due to competition with zooplankton for PUFA-rich food particles. However, zebra mussels did not have any impact on the transfer efficiencies of C, total FAs, N, and P. EPA, DHA, and P were transferred more efficiently than C from phytoplankton to zooplankton, while total FAs, which are commonly used as an energetic source, were transferred as efficiently as C. The enrichment of consumers with the most important substances relative to their basal food sources creates the potential for the successful transport of these substances across aquatic trophic webs.

Аннотация: Coelenterazine-v (CTZ-v), a synthetic derivative with an additional benzyl ring, yields a bright bioluminescence of Renilla luciferase and its "yellow" mutant with a significant shift in the emission spectrum toward longer wavelengths, which makes it the substrate of choice for deep tissue imaging. Although Ca2+-regulated photoproteins activated with CTZ-v also display red-shifted light emission, in contrast to Renilla luciferase their bioluminescence activities are very low, which makes photoproteins activated by CTZ-v unusable for calcium imaging. Here, we report the crystal structure of Ca2+-regulated photoprotein obelin with 2-hydroperoxycoelenterazine-v (obelin-v) at 1.80 angstrom resolution. The structures of obelin-v and obelin bound with native CTZ revealed almost no difference; only the minor rearrangement in hydrogen-bond pattern and slightly increased distances between key active site residues and some atoms of 2-hydroperoxycoelenterazine-v were found. The fluorescence quantum yield (phi(FL)) of obelin bound with coelenteramide-v (0.24) turned out to be even higher than that of obelin with native coelenteramide (0.19). Since both obelins are in effect the enzyme-substrate complexes containing the 2-hydroperoxy adduct of CTZ-v or CTZ, we reasonably assume the chemical reaction mechanisms and the yields of the reaction products (phi(R)) to be similar for both obelins. Based on these findings we suggest that low bioluminescence activity of obelin-v is caused by the low efficiency of generating an electronic excited state (phi(S)). In turn, the low phi(S) value as compared to that of native CTZ might be the result of small changes in the substrate microenvironment in the obelin-v active site.

Blends of poly-3-hydroxybutyrate and poly-ε-caprolactone: Morphology, properties and biocompatibility / A. N. Boyandin, A. A. Sukhanova, E. D. Nikolaeva [et al.] // AIP Conference Proceedings : American Institute of Physics Inc., 2021. - Vol. 2388: 4th International Conference on Modern Synthetic Methodologies for Creating Drugs and Functional Materials, MOSM 2020 (16 November 2020 through 20 November 2020, ) Conference code: 174383. - Ст. 020002, DOI 10.1063/5.0068677
Аннотация: A series of films was obtained from blends of poly-3-hydroxybutyrate (PHB) and poly-s-caprolactone (PCL). The structure, physical, mechanical and biological properties of the films were studied, depending on the ratio of the components. The microscopic structure of mixed films was determined by the main component of the blend: the films were porous with a predominance of PHB and relatively smooth with a predominance of PCL. The highest values of elongation at break (229-269%), as well as the local maximum values of tensile strength (14-15 MPa) were noted for blends with 5-25% PHB content. At PHB content of 25% and 75%, local maxima of Young's modulus were observed (507 and 655 MPa, respectively). When the ratio of the components in the blend was equal (50:50 by weight), the films were heterogeneous and had the lowest values of mechanical strength (ultimate strength and elongation at break were 3 MPa and 15.5%, respectively). A study of the biocompatibility of mixed films in a culture of NIH 3T3 mouse fibroblasts based on determination of the number of adhered cells in the MTT test showed the absence of cytotoxic action, as well as high adhesion and cell proliferation, in some cases exceeding the data for films from pure PHB and PCL. This demonstrates the suitability of PHB-PCL blends for the production of cell carriers for tissue engineering and other reconstructive technologies. © 2021 Author(s).

Аннотация: The efficacy of slow-release formulations of tribenuron-methyl (TBM) embedded in the matrix of degradable poly(3-hydroxybutyrate) blended with birch wood flour [polymer/wood flour/herbicide 50/30/20 wt.%] was compared with the efficacy of TBM as the active ingredient of the Mortira commercial formulation, which was applied as post-emergence spray to treat spring wheat cv. Novosibirskaya 15. The study was conducted in Central Siberia (in the environs of the city of Krasnoyarsk, Russia) from May to August 2020. The biological efficacy of the embedded TBM was 92.3%, which was considerably higher than the biological efficacy of the Mortira formulation used as the post-emergence spray (15.4%). The embedding of TBM into degradable blended matrix enabled long-duration functioning of this unstable herbicide in soil. The sensitivity of weed plants to TBM differed depending on the species. TBM was more effective against A. retroflexus and A. blitoides, which were killed at an earlier stage, than against C. album and G. aparine, whose percentage increased in the earlier stage and which were controlled by the herbicide less effectively and at later stages. On the plot treated with the embedded herbicide, the parameters of the wheat yield structure were the best, and the total yield was the highest: 3360 +/- 40 kg/ha versus 3250 +/- 50 kg/ha in the group of plants sprayed with the Mortira formulation. The grain produced in all groups was of high quality and was classified as Grade 1 food grain. The highest quality parameters (grain hectoliter mass, gluten, and protein contents) were obtained in the group of plants treated with the embedded herbicide. The study of the embedded TBM confirmed the high efficacy of the experimental formulation.

Аннотация: Films were prepared from 2% solutions of biodegradable poly-3-hydroxybutyrate [P(3HB)] and investigated. The polymer was synthesized by the Cupriavidus necator B-10646 bacterium cultivated using various carbon sources (glucose and glycerol of different degrees of purity, containing 0.3 to 17.93% impurities). Glycerol as the substrate influenced molecular-weight properties and crystallinity of the polymer without affecting its temperature characteristics. The P(3HB) specimens synthesized from glycerol had reduced Mw (300–400 kDa) and degree of crystallinity (50–55%) compared to the specimens synthesized from glucose (860 kDa and 76%, respectively). The low-crystallinity P(3HB) specimens, regardless of the degree of purity of glycerol, produced a beneficial effect on the properties of polymer films, which had a better developed folded surface and increased hydrophilicity. The values of the highest roughness (Ra) of the films synthesized from glycerol were 1.8 to 4.0 times lower and the water angles 1.4–1.6 times smaller compared to the films synthesized from glucose (71.75 nm and 87.4°, respectively). Those films performed better as cell scaffolds: the number of viable NIH fibroblasts was 1.7–1.9 times higher than on polystyrene (control) or films of P(3HB) synthesized from glucose. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.

Аннотация: The present study investigates, for the first time, the structure of the microbial community of cryogenic soils in the subarctic region of Siberia and the ability of the soil microbial community to metabolize degradable microbial bioplastic - poly-3-hydroxybutyrate [P(3HB)]. When the soil thawed, with the soil temperature between 5-7 and 9-11 degrees C, the total biomass of microorganisms at a 10-20-cm depth was 226-234 mg g(-1) soil and CO2 production was 20-46 mg g(-1)W day(-1). The total abundance of microscopic fungi varied between (7.4 +/- 2.3) x 10(3) and (18.3 +/- 2.2) x 10(3) CFU/g soil depending on temperature; the abundance of bacteria was several orders of magnitude greater: (1.6 +/- 0.1) x 10(6) CFU g(-1) soil. The microbial community in the biofilm formed on the surface of P(3HB) films differed from the background soil in concentrations and composition of microorganisms. The activity of microorganisms caused changes in the surface microstructure of polymer films, a decrease in molecular weight, and an increase in the degree of crystallinity of P(3HB), indicating polymer biodegradation due to metabolic activity of microorganisms. The clear-zone technique e plating of isolates on the mineral agar with polymer as sole carbon source e was used to identify P(3HB)-degrading microorganisms inhabiting cryogenic soil in Evenkia. Analysis of nucleotide sequences of rRNA genes was performed to identify the following P(3HB)degrading species: Bacillus pumilus, Paraburkholderia sp., Pseudomonas sp., Rhodococcus sp., Stenotrophomonas rhizophila, Streptomyces prunicolor, and Variovorax paradoxus bacteria and the Penicillium thomii, P. arenicola, P. lanosum, Aspergillus fumigatus, and A. niger fungi.

bacterial luciferase -- non-steady-state reaction kinetics -- viscosity -- diffusion limitation
Аннотация: Enzymes activity in a cell is determined by many factors, among which viscosity of the microenvironment plays a significant role. Various cosolvents can imitate intracellular conditions in vitro, allowing to reduce a combination of different regulatory effects. The aim of the study was to analyze the media viscosity effects on the rate constants of the separate stages of the bacterial bioluminescent reaction. Non-steady-state reaction kinetics in glycerol and sucrose solutions was measured by stopped-flow technique and analyzed with a mathematical model developed in accordance with the sequence of reaction stages. Molecular dynamics methods were applied to reveal the effects of cosolvents on luciferase structure. We observed both in glycerol and in sucrose media that the stages of luciferase binding with flavin and aldehyde, in contrast to oxygen, are diffusion-limited. Moreover, unlike glycerol, sucrose solutions enhanced the rate of an electronically excited intermediate formation. The MD simulations showed that, in comparison with sucrose, glycerol molecules could penetrate the active-site gorge, but sucrose solutions caused a conformational change of functionally important alpha Glu175 of luciferase. Therefore, both cosolvents induce diffusion limitation of substrates binding. However, in sucrose media, increasing enzyme catalytic constant neutralizes viscosity effects. The activating effect of sucrose can be attributed to its exclusion from the catalytic gorge of luciferase and promotion of the formation of the active site structure favorable for the catalysis.

Аннотация: The development of inexpensive, easy-to-produce, and easy-to-use analytical tools for detection of harmful and toxic substances is a relevant research problem with direct applications in environmental monitoring and protection. In this work, we propose a novel composite material based on alumina nanofibers and detonation nanodiamonds for detection of phenol in aqueous medium. The composite material was obtained by mixing an aqueous suspension of alumina nanofibers with a diameter of 10-15 nm and a length of several microns and a hydrosol of nanodiamonds with an average cluster size of 70 nm. The mechanisms underlying the interaction of these nanomaterials are clarified and the physicochemical properties of the composite are investigated. The SEM and TEM studies show that the obtained composite has a network structure, in which clusters of nanodiamonds (10-20 nm in diameter) are distributed over the surface of nanofibers. Coupling of nanomaterials occurs due to opposite signs of their zeta potentials, which results in electrostatic attraction and subsequent chemical bonding as indicated by the X-ray photoelectron spectroscopy and simultaneous thermal analysis. The bonding apparently occurs between functional groups (mainly carboxyl) on the surface of nanodiamonds and amphoteric hydroxyl groups on the surface of alumina nanofibers. The proposed composite allows an easy-to-perform colorimetric analysis for qualitative and quantitative determination of phenol in aqueous samples with linear response over a wide range of concentrations (0.5-106 mu M). Multiple tests have shown that the composite is reusable and retains its catalytic function for at least 1 year during storage at room temperature.

Аннотация: Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater temperatures, and vertical thermal gradients, in many lakes around the world. Though many studies highlight warming of surface water temperatures in lakes worldwide, less is known about long-term trends in full vertical thermal structure and deepwater temperatures, which have been changing less consistently in both direction and magnitude. Here, we present a globally-expansive data set of summertime in-situ vertical temperature profiles from 153 lakes, with one time series beginning as early as 1894. We also compiled lake geographic, morphometric, and water quality variables that can influence vertical thermal structure through a variety of potential mechanisms in these lakes. These long-term time series of vertical temperature profiles and corresponding lake characteristics serve as valuable data to help understand changes and drivers of lake thermal structure in a time of rapid global and ecological change.
