Keratinolytic Bacteria Isolated from Feather Waste
The aim of this study was to characterize keratinolytic bacteria isolated from feather waste. Four isolates were selected after growth on solid medium with feather meal as sole carbon and nitrogen source and screened for proteolytic activity on milk agar plates. Three isolates were Gram-negative (belonged to the genera Burkholderia, Chryseobacterium and Pseudomonas) and one was Gram-positive (M...
متن کاملKeratinolytic Potential of Feather-Degrading Bacillus polymyxa and Bacillus cereus
Keratinolytic abilities of Bacillus polymyxa B20 and B. cereus B5esz were evaluated in liquid cultures in mineral media containing chicken feathers. Both tested strains were capable of effective liquefying and biodegradation of feather keratin, up to 56.5 – 72.1% in ten-day cultures, releasing considerable amounts of hydrolysis products. Tested bacteria were mesophilic species, producing highes...
متن کاملInternational Journal of Pharma and Bio Sciences PRODUCTION OF KERATINOLYTIC ENZYME BY A NEWLY ISOLATED FEATHER DEGRADING BACILLUS SP. FROM CHICK FEATHER WASTE
A novel feather-degrading Bacillus Sp. was isolated from chick manure. The bacterium produces keratinolytic enzyme using chicken feather as a sole of carbon and nitrogen source. The effect of temperature, pH on keratinase production of this keratinolytic strain was studied. Maximum enzyme activities were obtained within 48 hrs (780U/ml) of cultivation. The optimal conditions for the keratinolyt...
متن کاملKeratin 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 کاملDegradation of Chicken Feather a Poultry Waste Product by Keratinolytic Bacteria Isolated from Dumping Site at Ghazipur Poultry Processing Plant
Feathers are byproduct waste of poultry processing plant and produced in large amount. A small percentage of feather waste is steamed, chemically treated, ground, to form feather meal a dietary protein supplement for animals. Alternatively, keratin can be biodegraded by some Keratinolytic bacteria and in this study Keratinase producing bacteria and their Keratinolytic enzyme production was inve...
