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 کاملIsolation, Identification and Characteristics of an Endophytic Quinclorac Degrading Bacterium Bacillus megaterium Q3
In this study, we isolated an endophytic quinclorac-degrading bacterium strain Q3 from the root of tobacco grown in quinclorac contaminated soil. Based on morphological characteristics, Biolog identification, and 16S rDNA sequence analysis, we identified strain Q3 as Bacillus megaterium. We investigated the effects of temperature, pH, inoculation size, and initial quinclorac concentration on gr...
متن کاملIsolation, identification, and characterization of a feather-degrading bacterium.
A feather-degrading culture was enriched with isolates from a poultry waste digestor and adapted to grow with feathers as its primary source of carbon, sulfur, and energy. Subsequently, a feather-hydrolytic, endospore-forming, motile, rod-shaped bacterium was isolated from the feather-degrading culture. The organism was Gram stain variable and catalase positive and demonstrated facultative grow...
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 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...
