Abstract
|
|
|
The crude enzyme, tamylase, was produced by cultivating the Bacillus subtilis on wheat bran. It is composed of amylase and protease, and can be used as an additive material to the synthetic detergent, Suny which is manufactured by Ae-kyung Oil and Fat Co.
Amylase activity of the enzyme as an additive material to the synthetic detergent;
1. is decreased by increasing the amount of detergent. But inhibitory rate under the practical used concentration of detergent is less than ten percents.
2. have optimal temperature at 40℃.
3. have optimal pH of substrate on pH 5∼6.5.
4. is inhibited by Fe^(+++).
When enzyme and detergent are mixed both as powder, the enzyme is goad for storage.
Proteolytic activity is good at the practical used concentration of the detergent, but it is inhibited by strong concentration.
