The invention relates to a production extracting method of superoxide dismutase, especially to a method for extracting refined copper/zinc superoxide dismutase from a microorganism saccharomyces cerevisiae. It is characterized in that it uses saccharomyces cerevisiae thallium to extract, purify and obtain the refined copper/zinc superoxide dismutase. The craft course is that it obtains the purified refining enzyme by saccharomyces cerevisiae thallium extracting enzyme, acetone secondary precipitation and DEAE-32 fiber column color printing. |
