Production Of Alkaline Protease From Bacillus licheniformis (NCIM 2044) And Media Optimisation For Enhanced Enzyme Production

ثبت نشده
چکیده

Production of alkaline protease from Bacillus licheniformis (NCIM 2044) was studied and characterized. Of different cheap source media chosen, maximum production of 172.425 U/ml was obtained for 1% wheat bran containing media. The enzyme assay at various optimum pH and temperatures were also determined.

Response of surface optimization for the enhanced production of alkaline protease isolated from Bacillus sp. with bean husk as a new substrate

Optimization of the fermentation medium for maximum alkaline protease production was carried out. Fifteen positive isolates were examined for their extent of alkaline protease production. The most potent producer was identified as Bacillus sp. The solid substrate screening showed that the combination of wheat straw and bean husk was the best one. The initial screening by using Plackett–Burman’s...

Batch Kinetics and Modeling of Alkaline Protease Production by Isolated Bacillus sp. (RESEARCH NOTE)

The aim of this study was the use of fish waste hydrolysate (FWH) as a substrate for alkaline protease production using isolated Bacillus sp. in a batch system. Then the fermentation kinetics of enzyme production was studied. The results show that with the addition of FWH to the fermentation medium with a final concentration of 4% (optimal concentration), alkaline protease value reached a maxim...
