The maximum growth temperatures, which vary from >15 and <20°C to >20 and <25°C for biotypes of yeast strain Cryptococcus antarcticus, affect fatty acid composition (Vishniac & Kurtzman, 1992). , 1990; Vani Saxena, 1998; Watson, 1987). nivalis, were examined by Watson et al. (1976). At temperatures lower than – 1°C and ethanol as a substrate, 90% of the total fatty acids were unsaturated with a predomination of linolenic (C18:3) from 35 to 50% and linoleic (C18:2) from 25 to 30% acids. At a temperature close to the maximum for growth 18°C linolenic acid constituted less than 20% of the total fatty acids, while oleic (20 to 40%) and linoleic (30 to 50%) acids were the major components.

Laboratory of Applied Microbiology – BAS, 26 Maritza Blvd 4002, Plovdiv, Bulgaria ABSTRACT Investigation of the C-source concentration (starch on the keratinase production by 2 termophilic actinomycetes strains was carried out. The strains were isolated from Antractic soil. The strains were isolated from Antractic soil. They were checked for proteolytic, caseinolytic and keratinase activity (the data show a positive effect of starch added for all enzymes checked).
ZLATANOV, L. KOLEVA, I. PISHTIYSKI in the content of proteins and carbohydrates in strains Rhodotorula minuta 16-3 and Candida oleophila 23-1 was observed. However, the quantity of lipids decreased considerably when the temperature was raised – in strain Rh. 03%, and in C. 05%. The results of strain Rh. 95%. The quantity of nucleic acids is equal to that of the protein for all strains. The data in Table 2 present the study of the effect of the addition of sodium chloride in culture medium on the biomass concentration and chemical composition of the yeasts.
