Optimization of Extracellular Alkaline Protease Enzyme from Bacillus Sp
Proteases are very important industrial enzymes, which contribute about 60% of the total world enzyme market. Among the various proteases, bacterial proteases are the most significant, compared with animal and fungal proteases (Rahman et al., 1994) and among bacteria, Bacillus sp are specific producers of extra-cellular proteases (Coolbear et al., 1992; Banerjee et al., 1999). These enzymes hav...
متن کاملStudies on Alkaline Protease Production from Bacillus sp
The aim of this study was optimization of the conditions for the production of alkaline protease from the Bacillus strains coded as L18, L21 and I18, which were isolated from our natural habitats. Additionally, the goal was also to optimize the production of alkaline protease from Bacillus sp. L21 in a new low-cost media formulation by employing design of experiments and response surface method...
متن کاملOptimization of alkaline protease production from a locally isolated Bacillus sp. ZR-5: Potential application as a detergent additive
The aim of this study was to optimize protease production using a novel Bacillus sp. ZR-5 strainisolated from the soil, and evaluate its application in detergent industry. The proteolytic activityof the strain was demonstrated using gelatin hydrolysis screening test. Protease productionoptimization was carried out using a two-step approach: a conventional method in order toidentify the best car...
متن کاملBatch 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...
متن کاملPurification and properties of a novel surface-active agent- and alkaline-resistant protease from Bacillus sp. Y.
In the course of a search for an alkaline stable protease for industrial use, an alkaline protease (protease BYA) was isolated from an alkalophilic Bacillus sp. Y, and its properties were characterized. Its optimum pH was pH 10.0-12.5, when casein was used as a substrate. In addition to the stability of protease BYA at pH 6.5-13.0, it was also very stable towards various surface-active agents, ...
