Abstract
The activities of penicillinases produced by Staphylococcus aureus, S9 were found to be affected by pH, temperature, substrate concentration and type of penicillin derivative used as a substrate. The optimal activities of penicillinases produced by S. aureus, S9 were obtained at pH 6, at 37 degrees C, 0.5-10 mu/ml penicillin G concentration, and by increasing the enzyme concentration.
摘要
已发现金黄色葡萄球菌S9产生的青霉素酶的活性受pH值、温度、底物浓度以及用作底物的青霉素衍生物类型的影响。金黄色葡萄球菌S9产生的青霉素酶在pH值为6、温度为37摄氏度、青霉素G浓度为0.5 - 10微克/毫升以及通过增加酶浓度的情况下可获得最佳活性。
