【摘要】 利用平板透明圈法作为初筛方法,从不同的酿造曲样中筛选出1株产纤溶酶酶活较高的米曲霉菌株SA-6,其产纤溶酶酶活为25U/mL。通过比较发现,可以用自制纤维蛋白代替纤维蛋白原和尿激酶测定发酵液的纤溶酶酶活,在大通量的菌株筛选过程中可以节省大量费用。更多还原

【Abstract】 A Aspergillus oryzae strain,SA-6,was isolated from different brewing koji samples using the clarity circle method on plate.The fibrinolytic enzymatic activity of SA-6 was 25 U/ml.It was showed through comparison that fibrinogen and thrombin couldbe replaced by fibrin to determine the activity of fibrinolytic enzyme,which could save much money during the screening of a large quantity of strains.更多还原
