【摘要】 利用纤维蛋白平板法筛选纤溶酶产生菌株并测定其纤溶酶活性。从土壤、豆豉、猪血粉中分别取样,分离到30株具有溶纤活性的菌株,其中来自土壤12株,豆豉10株,猪血粉8株。选择来自土壤,并与已报道的菌株菌落特征不同的34,37菌株号进行研究,测得其酶比活力分别为9.05,624U/mg.Pro。更多还原

【Abstract】 Fibrin plate method was used to screen fibrinolytic strain and to examine the fibrinolytic enzyme activity. 30 strains were found to possess fibrinolysis activities, in which 12 strains from soil , 10 from fermented soybean, and 8 from dried pig blood powder. For two strains, namely the serial number 34 and 37, which showed different colony characters as compared to that reported previously, a further research was conducted. Experiments showed that the enzyme activities in the two strains were 9.05U/mg·Pro and 624U/mg·Pro respectively.更多还原
