Immobilization of Keratinase from Aspergillus flavus K-03 for Degradation of Feather Keratin
Extracellular keratinase isolated from Aspergillus flavus K-03 was immobilized on calcium alginate. The properties and reaction activities of free and immobilized keratinase with calcium alginate were characterized. The immobilized keratinase showed proteolytic activity against soluble azo-casein and azo-keratin, and insoluble feather keratin. Heat stability and pH tolerance of keratinase were ...
متن کاملBiodegradation of crude oil by immobilized microbial cells in alginate beads produced by electrospraying technique
Background and Objective: Petroleum compounds are major contributors to aquatic environmental pollution. In recent years, biological treatments as environmental-friendly and cost-effective techniques have been used alongside the various physico-chemical methods. Microbial cell immobilization in hydrogel carriers has been the focus of researchers due to various advantages such as ease of microbi...
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 کاملOptimization 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 the Cellulase Free Xylanase Production by Immobilized Bacillus Pumilus
Background: The extracellular xylanase secreted by microorganisms is a hydrolytic enzyme, which arbitrarily cleaves the β-1, 4 backbone of the polysaccharide xylan; an enzyme used in the food processing, bio-pulping and bio-bleaching. The commercial production of the xylanase is limited because of a higher cost involvement, which can be overcome by the cost-effective production...
