[The taxonomic position, ecological aspects and physiological-biochemical characteristics of microorganisms having industrial importance].

The paper presents fundamental results of the investigations obtained in the Department of Physiology of Industrial Microorganisms at the Institute of Microbiology and Virology of the National Academy of Sciences of Ukraine for the recent 15-20 years, as well as the Department developments directed to creation of biotechnological preparations, products and processes, most of which have been put into practice of the national economy and health protection. Data have been presented concerning the study of systematics, biology and ecology of nocardioform and coryneform bacteria, lactic acid bacteria and yeasts. When studying physiological-biochemical peculiarities and biological effect of the studied microorganisms, considerable attention has been paid to growth physiology of lactic acid bacteria, yeasts, lectin-forming bacteria, to processes of shaping of fungal mycelium under the conditions of batch cultivation as well as to microorganisms which take part in sewage treatment for heavy metals and oil products. The work also deals with the problems of creation and application in the economy of preparations intended for treatment and prophylaxis of gastro-intestinal diseases of cattle, poultry and swine, for siloing fodder, of new lactic acid preparations of functional direction, technological grounds of sewage treatment for oil products and six-valent toxic chrome.
