[Effect of 2-amino-2-thiazoline on the level of lipid peroxidation products in different yeast species].

The influence of 2-amino-2-thiazoline on lipid peroxidation in yeasts Saccharomyces cerevisiae and Pichia guilliermondii has been studied in vivo and in vitro. In the case the radioresistance of diploid yeasts-saccharomycetes is changed the radioprotector can produce a direct effect on lipid peroxidation. Different radioprotective efficiency of the preparation with regard to different strains of one and the same yeast culture is explained by its different influence on the content of endogenous radioprotective factors exerting a control over the accretion of lipid peroxidation products. The observed differences in the lag-periods of peroxidation in Saccharomyces cerevisiae and Pichia guilliermondii correspond to the level of their natural antioxidant activity of lipids.
