固定化中性蛋白酶水解啤酒废酵母的研究

Hydrolysis of used brewer yeast with immobilized netral proteinase.

以离子交换树脂为载体,以成二醛为交联剂,固定化中性蛋白酶,再利用固定化的酶来水解啤酒废酵母。本文研究了不同水解时间和温度、不同的酶量对啤酒酵母水解的影响。通过研究发现,树脂styene—DVB D392对中性蛋白酶的固定化效果及固定化之后对酵母的水解效果比较好。

Neutral proteinase was immobilized on ion exchange resin and cross -linked with glutaraldehyde. The immobilized enzyme was then used to hydrolysis used brewer's yeast. The results showed that styene DVB D392 was the best carrier for the immobilization of the neutral proteinase.
