To date, the largest Russian rivers discharging to Arctic Ocean remain a “blank spot” on world map of data distribution microplastics in freshwater systems. This study characterizes abundance and morphology surface water Ob River its large tributary, Tom River, western Siberia. The average number particles for two ranged from 44.2 51.2 items per m3 or 79.4 87.5 μg respectively. Of recovered microplastics, 93.5% were less than 1 mm their dimension, group (45.5% total counts) consisted with...
Microbial sulfate reduction in acid mine drainage is still considered to be confined anoxic conditions, although several reports have shown that sulfate-reducing bacteria occur under microaerophilic or aerobic conditions. We measured rates of up 60 nmol S cm(-3) day(-1) oxidized layers gold tailings Kuzbass (SW Siberia). A novel, acidophilic, copper-tolerant Desulfosporosinus sp. I2 was isolated from the same sample and its genome sequenced. The genomic analysis physiological data indicate...
The dominant microbial components of fluids from wells in pristine and water-injected, high-temperature, Western Siberian oil fields, were analyzed by PCR-DGGE. Particular emphasis was placed on sulphate-reducing organisms, due to their ecological industrial importance. Bacterial phylotypes obtained the non-water-injected Stolbovoye field more diverse than those Samotlor field, which is subject secondary recovery reinjection recycled production water. majority both sites related Firmicutes....
Thermal ecosystems associated with underground coal combustion sites are rare and less studied than geothermal features. Here we analysed microbial communities of near-surface ground layer bituminous substance in an open quarry heated by subsurface fire metagenomic DNA sequencing. Taxonomic classification revealed dominance only a few groups Firmicutes. Near-complete genomes three most abundant species, 'Candidatus Carbobacillus altaicus' AL32, Brockia lithotrophica AL31, Hydrogenibacillus...
This preliminary study investigated the abundance of microplastic particles in gastrointestinal tracts dace (Leuciscus leuciscus L.) from Tom River, a large tributary Ob River West Siberia. A total 13 specimens 2+ to 4+ years age were studied. Microplastic extracted fish guts counted and classified by shapes sizes. In average 204 ± 28.7 items microplastics detected for one specimen. categorized as fragments irregular shape (70%), spheres (16%), films (7%) fibers (7%), with size ranging...
Here we report the draft genome sequence of acid-tolerant Desulfovibrio sp. DV isolated from sediments a Pb-Zn mine tailings dam in Chita region, Russia. The has size 4.9 Mb and encodes multiple K+-transporters proton-consuming decarboxylases. phylogenetic analysis based on concatenated ribosomal proteins revealed that strain clusters together with TomC magneticus. annotation have been deposited at GenBank under accession number MLBG00000000.
Fat-containing wastes that are generated as a result of industrial production food products and being accumulated in large quantities wastewater sewage treatment plants present serious environmental problem. Microorganisms decompose various types lipids may be potential candidates for creation commercial bioformulations fat destruction. The aim the study was to obtain pure cultures lipophilic bacteria from fat-containing wastes, their diversity activity development biological product. As...
The paper searches for new solutions the development of highbush blueberry orchards (Vaccinium corymbosum L. (1753)) in Western Siberia. All species genus Vaccinium display special symbiotic mycorrhizal associations with root systems-ericoid mycorrhiza, which essentially enhances formation adventitious and lateral roots. For first time, we obtained pure cultures micromycetes associated roots wild family Ericaceae Tomsk region, Russia. With regard to data molecular genetic analysis ITS region...
In vitro cultures of three varieties blue honeysuckle were obtained, the optimum time for material selection was determined and method explants sterilization developed.
The approaches are identified that increase the survival rate of honeysuckle microclones in process adaptation to ex virto conditions up 98%.
The work is focused on the selection of an appropriate substrate for solid-state fermentation using B. bassiana with aim a biopesticide production. highest number conidia was yielded during cultivation polished rice moistened water in ratio 1:1.5 and 1:2.
Pure cultures of lipophilic microorganisms different phylogenetic groups were isolated from fat-containing industrial wastewaters. The strains the genera Pseudomonas and Bacillus most active lipolytic microorganisms.
Аннотация.В ходе исследования проведена первичная оценка эффективности комбинированного биопрепарата, основанного на Beauveria bassiana и Bacillus thuringiensis var.thuringiensis, для контроля численности ряда характерных вредителей оранжерейных растений.Испытания биопрепарата проводили в отношении вредителей-фитофагов: паутинного клеща, мучнистого червеца пальмовой ложнощитовки
The specific growth rates of Pleurotus ostreatus, eryngii and Ganoderma lucidum were determined on different culture media. Based the data obtained, optimal substrates selected for further production artificial leather construction biomaterials using fungal mycelium.
Analysis of fatty acid composition in liquid culture media after lipophilic bacterial strains cultivation was carried out. Pure cultures were earlierisolated from fat-containing wastes and cultivated on with diverse fat sources. It shown that microorganisms hydrolyze animal milk fats to free acids.
Crystalline phases in biogenic sediments formed by Desulfotomaculum sp. DPr and Desulfovibrio KZ1 from geothermal sources were studied. Marcasite (FeS2), melnikovite (FeSххH2O) greigite (Fe3S4) detected. Composition of the crystalline phase depends on physicochemical conditions environment. The association crystals with cell surface, membranes periplasmic space was revealed. Intracellular crystallization presumably involves systems responsible for transport or cation chelation.
Bacterial strains with lipolytic activities Pseudomonas citronellolis A13, extremaustralis Б11, nitroreducens Д14, sp. B21, Microvirgula curvata B37, Brevibacillus 28Д, Bacillus subtilis spp. B10, B34 were isolated from fat-containing industrial wastewater of food industry and used for obtaining a lipophilic bacterial consortium that perspective fat deposits utilization.
Poultry waste composting in natural conditions is a rather slow process. Application of biological preparations based on thermo-tolerant and thermophilic microorganisms can intensify the compost maturation. Novel strains — organic matter destructors were isolated current work. The isolates identified as representatives Bacillus, Aneurinibacillus, Aeribacillus, Ureibacillus genera. Isolated be recommended for to accelerate poultry litter other livestock farming waste.
