摘要

A mutant strain C-491 with high yield of petinase was obtained from Aspergillus oryzae Z166 by physical mutagensis using ultraviolet and Co~(60) radiation. The enzyme activities of fermentation broth were 3577 u/ml for citrus pectin. The optimal medium for enzymer production were: malt extract (Malt sugar 6
