摘要: 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%。

Abstract: 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%.
