Optimization of Culture Conditions for Keratinase Production in Streptomyces Sp. JRS19 for Chick Feather Wastes Degradation
The aim of this study was to find the optimal conditions of a newly isolated Streptomyces strain JRS 19. Screening for keratinase producing bacteria and their keratinase production were investigated. The keratinase produced by the isolate was purified by chromatographic techniques and the optimum pH maintained was 7.0 and maintained at different temperatures Viz., 20ºC, 25ºC, 30ºC, 35ºC and 40º...

متن کاملEfficient Degradation of Feather by Keratinase Producing Bacillus sp.
Keratinase producing microorganisms are being increasingly utilized for degradation and recycling of poultry feather waste. Two native strains BF11 (Bacillus subtilis) and BF21 (Bacillus cereus) degrading keratin completely were characterized. The native strains produced more than 10 KU/mL of enzyme. Strain improvement resulted in isolation of MBF11 and MBF21 from BF11 and BF21 isolates, respec...
متن کاملOptimization of rhamnolipid production by Pseudomonas aeruginosa OG1 using waste frying oil and chicken feather peptone
In the present study, production of rhamnolipid biosurfactant by Pseudomonas aeruginosa OG1 was statistically optimized by response surface methodology. Box-Behnken design was applied to determine the optimal concentrations of 52, 9.2, and 4.5 g/L for carbon source (waste frying oil), nitrogen source (chicken feather peptone), and KH2PO4, respectively, in production medium. Under the optimized ...
