利用产黄青霉制备高活力蔗糖转化酶

Study on the preparation of High Activity Sucroce Invertase by using penicillium chrysogenum

利用产黄青霉发酵法制备具蔗糖转化酶活力的生物催化剂，制备工艺简单，无需特殊提纯手段。该酶制剂经研究表明：以10％蔗糖为底物，于37℃，pH7．0±0．5条件下，经6h连续转化可将10％蔗糖溶液完全转化为转化糖浆，其转化率达到100％。

築iocatalyst with high sucrose invertase activity was prepared by fermentation of penicillium chrysogenum, the preparation technology was simple and needed no specific purification process. With 10% sucrose as substrate, under 37℃, pH7. 0 ±0. 5and 6h contineous inversion, the 10% sucrose solution can be completely converted to invert sugar syrup, the percent conversion can be up to 100%.
