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 کاملEfficient Keratinolysis of Poultry Feather Waste by The Halotolerant Keratinase from Salicola Marasensis
Sustainable development in the bio-treatment of large-scale biomass bulks requires high performance enzymes adapted to extreme conditions. An extracellular keratinolytic extract was obtained from the culture broth of a halotolerant strain of Salicola marasensis. Keratin hydrolyzing activity of the concentrated enzyme extract was observed on a 100 mg of pretreated feather waste...

متن کاملSCREENING AND CHARACTERIZATION OF KERATINASE FROM Bacillus licheniformis ISOLATED FROM NAMAKKAL POULTRY FARM
Keratin are insoluble fibrous proteins found in hair, wool, feather, nail, horns and other epithelial covering which is rich in beta helical coil linked through cysteine bridges. Keratinase (EC 3.4.4.25) belongs to the class hydrolase which are able to hydrolyse insoluble keratins more efficient than other proteases. The bacteria Bacillus licheniformis showing higher keratinase activity was scr...
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...
