Abstract:
The aim of this present work was to explore the potential feather-degrading bacterial isolates were isolated from poultry farm soil. Isolation and screening of keratinase-producing bacterial isolates were performed in keratin agar medium. The potential keratinase-producing bacterial isolates were identified using morphological, biochemical and molecular characterization. Degradation of chicken feather was optimized using different nutrient or physical factors in feather meal broth medium. Soluble peptide, amino acid and free thiol group liberation during feather degradation were estimated too. The isolated bacterial isolates were found significantly degrading the chicken feathers with keratinase enzyme production. The present study revealed a significantly novel feather-degrading Geobacillus thermodenitrificans PS41 bacterial isolate, isolated from poultry farm soil.
