Regulation of extracellular protease production in Bacillus cereus.
Both sporulation and protease production can be inhibited by growing Bacillus cereus T in a medium containing a high concentration of a mixture of amino acids. Mutants selected for the ability to sporulate in this inhibitory medium were found to produce high levels of protease in the normal and inhibitory media. Comparison of the mutant and wild-type enzymes by gel electrophoresis and heat inac...
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 کاملProduction of kanosamine by Bacillus cereus UW85.
Bacillus cereus UW85 produces two antibiotics that contribute to its ability to suppress certain plant diseases (L. Silo-Suh, B. Lethbridge, S. J. Raffel, H. He, J. Clardy, and J. Handelsman, Appl. Environ. Microbiol. 60:2023-2030, 1994). To enhance the understanding of disease suppression by UW85, we determined the chemical structure, regulation, and the target range of one of the antibiotics....
متن کاملOptimization and Production of Alkaline Protease enzyme from Bacillus subtilis 168 isolated from food industry waste
Proteases, one among the three largest groups of industrial enzymes, accounts for about 60% of the total worldwide sale of enzymes from biological sources since they possess almost all characteristics desired for their biotechnological applications (Adinarayana et al., 2003). Among the various proteases, bacterial protease was the most significant compared with animal, fungi and plant protease....
متن کاملProduction and optimization of extracellular Alkaline Protease from Bacillus subtilis isolated from dairy effluent
Proteolytic bacteria are most important for industries such as food and fermentation. Thus isolating and manipulating pure culture from various sources has importance for various biotechnology industries. In the present investigation a total of 26 bacteria were isolated from the dairy plant effluent. All isolates were screened for proteolytic activity using alkaline skim milk agar plate, among ...
