Optimization of fermentation condition for cellulase enzyme production from Bacillus sp.



Cellulase is an important enzyme in present-day of industrial biotechnology. The current study is concerned with the production and partial characterization of cellulase enzyme from Bacillus sp. The effect of various fermentation conditions for cellulase production through shake-flask culture was investigated. Maximum enzyme production was obtained after 24 hours of incubation in fermentation medium with pH 3.5 at 35°C under having agitation at 150 rpm while inoculums volume 1% was applied. Enzyme production was 1.91 times higher after optimizing the production condition as compared to the basal media. Cellulase characterization revealed that optimum activity was at pH 5.5 and 50°C for 50 minutes. About 68% of the activity retained after heating the crude enzyme solution at 50°C for 30 minutes. This nature makes cellulase a suitable candidate for current mainstream biomass conversions for sustainable agriculture and industrial processes.
