蛋白酶和纤维素酶协同水解豆渣的工艺

Hydrolysis of Soybean Sregs by Proteases and Cellulase for Fermentation Medium

采用碱性蛋白酶和纤维素酶协同水解豆渣制备发酵基料,并分析豆渣酶解液的成分。结果表明,豆渣与水以1∶4(质量比)的比例混合,调节豆渣液pH 7.0,添加碱性蛋白酶6 000 U/g同时加入纤维素酶1.5%(以豆渣干重计),55℃水解4 h后,可用作发酵培养基制备豆渣发酵活性成分。

The producing method of hydrolysates of soybean dregs were studied. Soybean dregs were dilluted with distilled water at 1：4 （weight ratio）. After adjusted solution pH 7.0, hydrolyzed by 6 000 U/g alcalase and 1.5 % cellulase （dry soybean dregs） for 4 h at 55 ℃, the hydolysate can be used fertimentation culture for producing active ingredient.
