The experimental data of the past decade concerning the metabolic peculiarities of aerobic methylobacteria and the prospects for their use in different fields of modern biotechnology, including genetic engineering techniques, have been summarized.
The authors’ and literature data on the adaptation response of the micromycetes Yarrowia lipolytica to various stress impacts are considered in the review. The uniformity of cellular response to all stress factors is discussed.
The review summarizes the authors’ own data and reports by other researchers concerning the degradation of stable organic compounds by actinobacteria. Properties of these microorganisms are characterized. They include the ability to survive and to maintain metabolic activity during prolonged...
The review summarizes the data on the metabolic potential of methanotrophs as producers of biopolymers, alternative biofuel, bioprotectants, and other secondary metabolites. The work provides the examples of modern ‘omic’ technologies used for genetic engineering of efficient methanotrophic...
We isolated 50 strains of free-living ultrasmall bacteria with a cell volume that varies from 0.02 to 1.3 μm3 from a range of natural biotopes, namely permafrost soils, oil slime, soils, lake silt, thermal swamp moss, and the skin integuments of the clawed frog, Xenopus laevis. Of them, 23...
Selected filamentous fungi—98 strains of 31 genera—were screened for the ability to catalyze 11β-hydroxylation of 6α-fluoro-16α-methyl-deoxycorticosterone 21-acetate (FM-DCA). It was established that representatives of the genera Gongronella, Scopulariopsis, Epicoccum, and Curvularia have the...
The transformation of dehydroepiandrosterone by Spicaria fumoso-rosea VKM F-881 produced 7α- and 7β-hydroxy-dehydroepiandrosterone, 3β,7α-dihydroxy-17a-oxa-D-homo-androst-5-en-17-one, and 3β,7β-dihydroxy-17a-oxa-D-homo-androst-5-en-17-one. The yield of the main...
This review analyzes the issues associated with biodegradation of glyphosate (N-(phosphonomethyl)glycine), one of the most widespread herbicides. Glyphosate can accumulate in natural environments and can be toxic not only for plants but also for animals and bacteria. Microbial transformation and...
The degradation of petroleum hydrocarbons by plant-microbial associations, as well as the peculiarities of the interaction between microorganisms in consortium and the associated plants, have been studied. It was shown that degrader microorganisms that are part of the consortium Rhodococcus...
The effect of phosphate concentration in the culture medium on the growth and naphthalene degradation by Pseudomonas putida BS 3701 was studied. The limiting concentration of phosphate was 0.4 mM and 0.1 mM under cultivation in media with naphthalene and glucose, respectively. The phosphate...
