| Abstract: | A high Cu{2} resistant Saccharomyces cerevisiae (SC) mutant was obtained by composite mutation with UV and NTG and SC monoploid as starting strain. Later its biological function was studied. The results showed that its resistance against UV and ionizing radiation, OH free radical clearing, and detoxification against Cu{2} were higher to some extent than the starting strain, and its genetic stability was maintained over 96%. |
