Optimization of the production and characterization of milk clotting enzymes by Bacillus subtilis natto
Suitable medium for production of milk clotting enzyme (MCE) by Bacillus subtilis (natto) Takahashi in submerged liquid-state fermentation was screened, the nutrient factors affecting MCE production was optimized by response surface methodology. The MCE production by B. subtilis (natto) Takahashi was increased significantly by 428% in the optimal medium developed. The MCE was filtered and conce...
متن کاملEnhanced Production of Vitamin K2 from Bacillus subtilis (natto) by Mutation and Optimization of the Fermentation Medium
The aim of this study was to enhance the production of vitamin K2 by using N-methyl-N-nitro-N-nitroso-guanidine (NTG) and low energy ion beam implantation and optimizing the fermentation medium. Mutation resulted in 1.66fold higher production of vitamin K2 than that of the parentl strain. The production by the mutant BN-P15-11-1 was increased 55% and reached 3.593±0.107 mg/L by using the Placke...
متن کاملStudies on the production of milk-clotting enzymes, proteolytic enzymes and mucilage by fungi.
Of 48 fungal isolates, 28 (including one Penicillium and three Aspergilli) secreted milk-clotting enzymes. This activity was in general related to the mycelial growth of a given isolate, but not with pH change of the culture filtrate during incubation. It was not found when mucilage was formed by isolates capable of doing so. The ratio of general proteolytic activity to milk-clotting activity v...
متن کاملoptimization of keratinase production for feather degradation by bacillus subtilis
results the pcr approved the bacillus genus of the isolates. the strain of bacillus subtilis was identified using biochemical tests. 40 ºc and ph 11 are the optimum condition for maximum keratinase enzyme activity. objectives the aim of this study was the isolation of feather degrading bacillus spp.from a poultry waste and the optimization of conditions for the highest enzyme activity and feath...
متن کاملElimination of plasmid-linked polyglutamate production by Bacillus subtilis (natto) with acridine orange.
Treatment of Bacillus subtilis (natto) strains Asahikawa, F, and M with acridine orange resulted in the conversion of approximately 64.2% of the Asahikawa population, 22.4% of the F population, and 9.2% of the M population to polyglutamate-nonproducing colonies. Such curing is suggestive of the involvement of plasmid DNA. Samples of cleared lysates of both parental and their cured strains were ...
