Keratin Production by Decomposing Feather Waste Using Some Local Bacillus spp. Isolated from Poultry Soil
Background; Feather waste is generated in large amounts as a by-product of commercial poultry processing. The main component of feather is keratin. The main purpose of this study was to identify Bacillus spp. (the keratinolytic bacteria) that are able to degrade the feather for producing keratin. Methods; Bacillus spp. Were isolated from the waste of poultries located in Miyaneh city. The bact...
متن کاملIsolation, identification and characterization of feather degrading bacteria
The present study deals with isolation, identification and characterization of feather degrading bacterium. The keratinolytic bacteria were isolated from feather dumped soil. The colonies showed higher keratinase production was identified as Bacillius sp, as per Bergey’s manual method. Keratinase producing Bacillus sp, showed higher enzymes production. The crude filtrate showed specific activit...
متن کاملEnzymatic Formulation Capable of Degrading Scrapie Prion under Mild Digestion Conditions
The prion agent is notoriously resistant to common proteases and conventional sterilisation procedures. The current methods known to destroy prion infectivity such as incineration, alkaline and thermal hydrolysis are harsh, destructive, environmentally polluting and potentially hazardous, thus limit their applications for decontamination of delicate medical and laboratory devices, remediation o...
متن کاملInternational Journal of Pharma and Bio Sciences IMPACT OF NEWLY ISOLATED BACILLUS MEGATERIUM (A1) ON DEGRADATION OF FEATHER WASTE
Feather keratin is highly resistant to degradation, but some keratinase producing microorganisms can easily degrade these insoluble keratins. These keratinase producing species have an important application in removal of poultry waste and recycled into valuable byproduct. A feather-degrading bacterium with high keratinase activity was isolated and identified as Bacillus megaterium (A1). The sel...
متن کاملOptimization 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...
