title: [Species composition and biochemical properties of yeasts from the water of the Bratsk reservoir].
abstract: The specific composition of 370 yeast strains isolated from the water of the Bratsk Reservoir was studied. The strains were assigned to 7 genera and 16 species according to their morphological, cultural, and physiologo-biochemical properties. Asporogenous forms prevailed; 52 strains possessed the amylolytic activity. The proteolytic activity was found in the cultures very seldom. The capability to assimilate organic phosphorus compounds was detected in 8% of the strains, and the ability to use inorganic phosphorus compounds was registered in 38% of the strains. Up to 95% of the strains utilized oil; 88%--engine oil; 43%--phenol. The specific yeast composition varied depending on the biotype.
