Keratinolytic 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 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 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 کاملIsolation and Screening of a Feather-Degrading Keratinolytic Actinomycetes from Actinomyces sp
The Actinomycetes comprise a ubiquitous order of bacteria which exhibits wide physiological and morphological diversity. These microorganisms are particularly abundant in alkaline soils rich in organic matter. Keratin is an insoluble structural protein of skin, and its derivatives (e.g. feather, hair, wool and horn) are known for their high stability. Actinomycetes producing keratinases are hav...
متن کاملisolation and identification of bacillus species from soil and evaluation of their antibacterial properties
conclusions this study indicated that some bacillus species have the potential to produce antimicrobial compounds which can be used to control microbial infections. results the identified bacillus species included b. cereus (86.6%), b. subtilis (6.6%), b. thuringiensis (3.3%), and b. pumilus (3.3%). evaluation of the antimicrobial activity of the extracted compounds was carried out against five...
