Efficient 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 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 کاملArsenic species in poultry feather meal.
Organoarsenical drugs are widely used in the production of broiler chickens in the United States. Feathers from these chickens are processed into a meal product that is used as an animal feed additive and as an organic fertilizer. Research conducted to date suggests that arsenical drugs, specifically roxarsone, used in poultry production result in the accumulation of arsenic in the keratinous 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...
