摘要
Abstract
Several fibrinolytic enzyme-producing strains with different colony morphology were isolated from Douchi. A strain DC-12 with higher fibrinolytic activity was treated with ultraviolet rays and HNO2. Three mutants DC-12N8, DC-12N10 and DC-12U8 with high yield of fibrinolytic enzyme and high stability were obtained, and their enzyme production increased by 3.6-fold, 3.7-fold and 4.75-fold as compared with those of the original strain, respectively.关键词
