NUKLEASEREDUKTION |
摘要 |
A method for reducing nuclease activity in a subtilisin solution obtained from a fermentation broth comprising 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; c) adjusting the temperature of the subtilisin solution to a temperature in the range of from 50° C. to 80° C.; whereby the nuclease activity is reduced to less than 5% of the initial value and the subtilisin activity is maintained at more than 80% of the initial value. |
