[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--9.2, even in the presence of high concentrations (0.5--3 M) of such chlorides as KCl, NaCl and CaCl2. The lipolytic activity of S variant of D. hansenii 8 was higher than the activity of its R variant.
