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 .
