【Abstract】 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.更多还原
