摘要 小四孢菌(Microtetrasporasp)在不同的转化培养基和培养条件下,转化美伐他汀(Mevastatin)为普伐他汀(Pravastatin)。在转化培养基A,初始底物浓度为500mg/L时,摇瓶发酵7d,转化率为50.14%,Pravastatin产量达260mg/L;在3L发酵罐中间歇补加底物和1~4g/L葡萄糖,培养11d,Pravastatin产量达375mg/L,转化率为45.2%。 Pravastatin was converted from Mervas-tatin on the different media and fermentation con-ditions by Microtetraspora sp.260mg Pravastatin/L and50.14%conversion rate was obtained at7days flasker incubation with initial500mg Mervastatin/L.It yielded375mg Pravastatin/L and getted conver-sion rate45.2%at11days jar fermentation with the intermittently adding Mevastatin and14g glu-cose /L.
