摘要
介绍了用超滤代替硫铵沉淀浓缩青霉素酰化酶的方法 ,不仅可缩短浓缩时间 ,而且能有效地去除其中小分子杂质。研究了膜的截留分子量。
This paper introduces the technique of condensed penicillinacylase with ultrafiltration instead of precipitated ammonium sulfate. It was found that using ultrafiltrated membrane not only would save the concentrated time, but also could effectively remove iow molecular impurities.The influence of blocked molecular weight of membrane, operating conditions and temperature on the penicillinacylase activity was studied.
