Optimization for Keratinase Enzyme Production Using Bacillus thuringiensis TS2
Keratinase producing bacterial strains were isolated from the chicken feather dumping site. Keratinase producing bacterial strains were identified by physical, biochemical characteristics, fatty acid methyl ester (FAME) and 16S rDNA sequences. Medium optimization of the selected keratinase producing bacterial strain (Bacillus thuringiensis TS2) was checked with various parameters such as incuba...
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 کاملCharacterization of the keratinolytic activity of indigenous Bacillus subtilis keratinase
Keratins are water insoluble proteins of our environment. Being extremely resistant to degradation by proteolytic enzymes, keratins are digested mainly by alkali and keratinase enzymes. The aim of present study was to characterize the indigenous keratinase for potentials of keratin-degrading activities. We report the purification and characterization of keratinase from Bacillus subtilis isolate...
متن کاملSCREENING AND CHARACTERIZATION OF KERATINASE FROM Bacillus licheniformis ISOLATED FROM NAMAKKAL POULTRY FARM
Keratin are insoluble fibrous proteins found in hair, wool, feather, nail, horns and other epithelial covering which is rich in beta helical coil linked through cysteine bridges. Keratinase (EC 3.4.4.25) belongs to the class hydrolase which are able to hydrolyse insoluble keratins more efficient than other proteases. The bacteria Bacillus licheniformis showing higher keratinase activity was scr...
متن کاملProduction and biochemical characterization of a thermostable phytase from Bacillus amyloliquefaciens LOR10
Phytase can improve the nutritional value of plant-based foods by enhancing protein digestibility and mineral availability through phytate digestion in the stomach and the food processing industry. Microbial sources are more promising for the production of phytases on a commercial scale. The objectives of this exploration were to screening and isolation of phytase-producing bacteria from hot sp...
