摘要
Abstract
Ethyl methane sulphonate (EMS) was used to induce saccharomyces cerevisiae, and obtained 5 mutants, low-yielding procinase A, with acid-denatured acid-denatured hemoglobin plate. All mutants were further screened through repeated fermentations. Some physical properties were measured. The results showed that fermenting power, biacetyl and flavor components of strain E10 were as much as that of the original strain. Its capacity of yielding proteinase A was much lower than that of original strain, and the mutant strain had the hereditary stability.关键词
