Antistress effect of extracellular peptides on UV irradiated yeast of different phylogenetic groups was studied. Yeast from different ecotopes and taxonomic groups exposed to UV radiation of a lethal intensity showed a protective effect and reactivating effect with participation of extracellular peptides. The highest protective activity was found in peptide reactivation factors (RFs) of bakery yeast-Saccharomyces cerevisiae, Kluyveromyces fragilis, and Candida utilis; the highest reactivating activity was exhibited by factors of the above-mentioned cultures and Debariomyces hansenii. Cross-protective and reactivating effects of RFs of yeast belonging to different taxonomic groups were demonstrated. Cross-protection increased two to three times after preexposure of reactivation factors to UV light (activation) in contrast to their reactivating effect. |
