[The biology of bacteria that assimilate C1--C2 compounds and the biotechnology aspects of their use].

Main directions of the research work of the Department of Biology of Gas-Oxidizing Microorganisms are described in the paper. Fundamental studies concern ecology, selection, taxonomy, physiology, biochemistry, genetics of bacteria utilizing C1--C2 compounds, mathematical simulation of microbiological processes. Applied studies are devoted to development of scientific basis of biotechnologies for synthesis of important products (single cell protein, exopolysaccharides, food ingredients, biogas) from non-food substrates, search for the hydrocarbon deposits and protection of the environment.
