[Fatty acid and fractional makeup of the lipids of osmotolerant yeasts].

Osmotolerant yeast cultures differ in their fatty acid and fraction composition of total lipids from yeast cultures of the same or related species from other habitat. Their lipid fatty acids are represented by C14--C18 acids. Their fraction composition of lipids is characterized by a low content of free fatty acids and diglycerides and an elevated content of esters of sterines and wax.

[Lipolytic activity of osmotolerant yeasts].

The ability to hydrolyse olive oil, cod-liver oil, caviar oil, and yeast oil was studied in osmotolerant yeasts Candida mogii 2, Debaryomyces hansenii 8, and Rhodotorula rubra 9, isolated from salted caviar. The lipolytic activity was manifested at 5, 15 and 26 degrees C and pH 4.0--9.

[Candida mogii and Debaryomyces hansenii yeast development in the presence of metal chlorides].

The yeasts Candida mogii 2 and Debaryomyces hansenii 8 isolated from salted fish spawn in the process of its storage were found to be capable of growth in 4 M KCl, 3 M MgCl2, 2.5 M NaCl, 1.5 BaCl2 and 1 M CaCl2.
