    摘要： The present disclosure relates to a method for reducing nuclease activity in a subtilisin solution obtained from a fermentation broth including: a) adjusting the pH of the subtilisin solution to a pH in the range of from pH 8.5 to pH 10.5; b) adding a polyol; and c) adjusting the temperature of the subtilisin solution to a temperature in the range of from 50° C. to 80° C. In accordance with the present disclosure, the nuclease activity is reduced to less than 5% of the initial value and the subtilisin activity is maintained at more than 60% of the initial value.

    摘要： The present invention relates to a method for the processing of hides or skins into leather, comprising enzymatic treatment of the hide or skin with carbohydrase in the soaking step. The present invention can achieve optimal fiber opening results in a relatively short period of time and at the same time does not cause loose grain, and meanwhile the pollution or impact on the environment is reduced in a maximum way.
