Аннотация: Measurements of trace elements incoming and exiting ''Bios-3'' biological-engineering life support system evidence presence of a source of these elements inside the system. This source is, most probably, structural units (steel walls, hose rubber, plastic coatings), catalysts of the thermal catalytic incinerator, expanded clay aggregate mechanically fixing plants and so on. The trace elements are received by the nutrient solutions and build up in the plant biomass. As a consequence the crew may receive elevated doses of such trace elements as aluminum, lead, nickel, chromium. To reduce income of trace elements to LSS requires thorough selection and preliminary treatment of structural materials with reduced desorption capacities and running-in of the system in idle mode prior to exploitation. This mode involves operation of the engineering part of the system (without plants and humans, but with nutrient solutions) for several months.

Аннотация: The suggested model of plastic garbage degradation allows us to obtain an estimate of the stationary density of their distribution over the surface of the World Ocean with account for the temperature dependence on the degradation rate. The model also allows us to estimate the characteristic time periods of degradation of plastic garbage and the dynamics of the mean density variation as the mean rate of plastic garbage entry into the ocean varies.

Constructing Slow-Release Formulations of Ammonium Nitrate Fertilizer Based on Degradable Poly(3-hydroxybutyrate) / A. N. Boyandin [et al.] // J. Agric. Food Chem. - 2017. - Vol. 65, Is. 32. - P6745-6752, DOI 10.1021/acs.jafc.7b01217 . - ISSN 0021-8561

Аннотация: The present study describes construction and investigation of experimental formulations of ammonium nitrate embedded in a matrix of degradable natural polymer poly-3-hydroxybutyrate [P(3HB)] and P(3HB) blended with wood flour shaped as tablets, some of them coated with P(3HB). Kinetics of ammonium release into soil as dependent on the composition of the polymer matrix was investigated in laboratory experiments. The rates of fertilizer release from formulations coated with a biopolymer layer were considerably (two months or longer) slower than the rates of fertilizer release from uncoated formulations, while release from polymer and composite (polymer/wood flour) formulations occurred with comparable rates. The use of the experimental formulations in laboratory ecosystems with wheat (Triticum aestivum L.) was more effective than application of free ammonium nitrate. The advantage of the slow-release fertilizer formulations is that they are buried in soil together with the seeds, and the fertilizer remains effective over the first three months of plant growth. The use of such slow-release formulations will reduce the amounts of chemicals released into the environment, which will curb their accumulation in food chains of ecosystems and mitigate their adverse effects on the biosphere. © 2017 American Chemical Society.

Screening of biopolymeric materials for cardiovascular surgery toxicity—Evaluation of their surface relief with assessment of morphological aspects of monocyte/macrophage polarization in atherosclerosis patients / N. G. Menzyanova [et al.] // Toxicol. Rep. - 2019. - Vol. 6. - P74-90, DOI 10.1016/j.toxrep.2018.11.009 . - ISSN 2214-7500

Аннотация: The morphotypes of human macrophages (MPh) were studied in the culture on nano-structured biopolymer substrates, made from polyhydroxyalcanoates (PHAs) of five various monomer compositions, followed by the solvent evaporation. Its surface relief, which was further in direct contact with human cells in vitro, was analyzed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). It was shown, that the features of the micro/nano relief depend on the monomeric composition of the polymer substrates. Monocytes (MN) of patients with atherosclerosis and cardiac ischemia, undergoing stenting and conventional anti-atherosclerotic therapy, were harvested prior and after stenting. MN were isolated and cultured, with the transformation into MPh in direct contact with biopolymer culture substrates with different monomer composition and nano-reliefs, and transformed into MPh, in comparison with the same process on standard culture plastic. Sub-populations of cells with characteristic morphology in each phenotypic class were described, and their quantitative ratios for each sample of polymers were counted as an intermediate result in the development of “smart” material for cardiovascular devices. The results obtained allow us to assume, that the processes of MPh differentiation and polarization in vitro depend not only on the features of the micro/nano relief of biopolymer substrates, but also on the initial state of MN in vivo and general response of patients. © 2018 The Authors

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 °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 day?1. The total abundance of microscopic fungi varied between (7.4 ± 2.3) ? 103 and (18.3 ± 2.2) ? 103 CFU/g soil depending on temperature; the abundance of bacteria was several orders of magnitude greater: (1.6 ± 0.1) ? 106 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 – plating of isolates on the mineral agar with polymer as sole carbon source – 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. © 2020 Elsevier Ltd

Constructing slow-release formulations of herbicide metribuzin using its co-extrusion with biodegradable polyester poly-ε-caprolactone / A. N. Boyandin, E. A. Kazantseva // J. Environ. Sci. Health Part B Pestic. Food Contamin. Agric. Wastes. - 2021, DOI 10.1080/03601234.2021.1911206 . - Article in press. - ISSN 0360-1234

Аннотация: Different technologies to prepare long term pesticide forms include polymer coating, preparing composites and encapsulating pesticides in nanoparticles. A simple and low-cost method was proposed to obtain slow-release formulations by co-extrusion of a pesticide with a biodegradable polymer at a temperature above the melting points of both components. A herbicide metribuzin and low-melting polyester poly-?-caprolactone were chosen for this work. Formulations containing 10%, 20%, and 40% herbicide were prepared. During 7 days of their exposition in water, it was released from 81% to 96% of initially loaded metribuzin; the highest release was detected for 40%-loaded forms. Biodegradation of the constructs and pesticide release were further studied in the model soil. Degradation rates of the specimens increased with an increase in pesticide content, from 9% to 20% over 14 weeks for the 10%/20%-loaded and the 40%-loaded specimens, respectively. The release of metribuzin reached, respectively, 37–38% and 55%. The herbicide content in soil was lower due to its partial degradation in soil; it reached 23–25% and 33%, respectively, from initially loaded into the polymer matrix. Release kinetics of metribuzin in water as in soil best fitted the First-order model. The used approach is promising for obtaining long-term release formulations for soil applications. © 2021 Taylor & Francis Group, LLC.
