An a-keratinase producing strain was isolated with wool as the sole carbon and nitrogen source and identified as Bacilluspumilus K9. The major amino acids liberated from the keratin degradation of wool by B. pumilus K...
Earth has been documented as a natural territory for fungi which cover individual kingdom with evolution. In subsequently vertebrates developed keratin which was a part of life as a structural aspect. Few moulds have ...
Energetic Bacillus subtilis was preliminarily isolated from feather meal selection medium experiment, which could be used to produce Keratinase. Through using the ultraviolet ray produced by ultraviolet light and the ...

A two-stage system was developed which combines the biological degradation of keratin-rich waste with the production of biogas. Chicken feather waste was treated biologically with a recombinant Bacillus megaterium str...
The aim of this study was to purify and characterize a keratinase produced by a new isolated Bacillus subtilis KD-N2 strain. The keratinase produced by the isolate was purified using ammonium sulphate precipitation, S...

A new feather-degrading bacterium was isolated from a local feather waste site and identified as Bacillus subtilis based on morphological, physiochemical, and phylogenetic characteristics. Screening for mutants with e...
Keratinous wastes could be degraded by some microorganisms in nature. Native human foot skin (NHFS) was used as sole nitrogen source to screen microorganisms with keratin-degrading capability. From approximately 200...
