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 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...
متن کاملDetermination of Keratinolytic Potential of Keratinolytic Fungi on Poultry Feather Samples Isolated from Selected Poultry Sites
The keratinolytic potential of the kearatinolytic fungi was determined by the release of protein by utilizing feather keratin. The total protein yield was found to be 430 ug mL -1 from Chrysosporium indicum, 410 ug mL -1 protein from Microsporum canis, 390 ug mL -1 protein from Crysosporium keratinophillum, 370 ug mL -1 protein from Microsporum gypseum, 360 ug mL -1 protein from Trichophyton ru...
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...
