Application
Protease from Bacillus sp. has been used:
- to evaluate protease inhibitor activity
- in high yields in batch fermentation using a response surface methodology
- in a study to investigate a biosensor to detect a protease biomarker from Bacillus licheniformis
General description
Protease from Bacillus sp. is extensively useful in pharmaceutical, leather, food and waste processing industry. It is widely used in manufacturing protein hydrolysates. Analysis of Bacillus protease stability and activity showed that the enzyme was active at all pH values from 5.0-11.0 with 100% activity at 8.0. Optimal pH for protein stability was determined to be at 7.0 while the optimal temperature for stability was at 60°C with 95% activity maintained.
