Microbial keratinases have become biotechnologically important since they target the
hydrolysis of highly rigid, strongly cross-linked structural polypeptide “keratin” recalcitrant to …

Keratinases are exciting proteolytic enzymes that display the capability to degrade the
insoluble protein keratin. These enzymes are produced by diverse microorganisms …

Keratin-rich wastes in the form of feathers, hair, nails, and horn are highly available as
byproducts of agroindustrial processing. The increased needs for energy conserving and …

Proteases are ubiquitous enzymes that occur in various biological systems ranging from
microorganisms to higher organisms. Microbial proteases are largely utilized in various …

A novel feather-degrading microorganism was isolated from poultry waste, producing a high
keratinolytic activity when cultured on broth containing native feather. Complete feather …

Billions of animals migrate each year. To successfully reach their destination, migrants must
have evolved an appropriate genetic program and suitable developmental, morphological …

Microbial fuel cells (MFCs) are often inoculated from a single wastewater source. The extent
that the inoculum affects community development or power production is unknown. The …

Feather waste is the highest protein-containing resource in nature and is poorly reused.
Bioconversion is widely accepted as a low-cost and environmentally benign process, but …

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 …

Poultry feathers are widely discarded as waste worldwide and are considered an
environmental pollutant and a reservoir of pathogenic bacteria. Therefore, develo** …
