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 کاملWaste Chicken Feather as Reinforcement in Cement-Bonded Composites
This study investigated the use of waste chicken feather (barbs and rachis) as reinforcement in cement-bonded composites. A series of composite boards consisting of various proportions of waste feather, cement, sand, and chemical admixtures were prepared. Mix workability decreased significantly as the proportion by weight of feathers or ground feathers increased from 5% to 20%. Boards containin...
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 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...
