Feathers are a major by-product of the poultry industry. They are mainly composed of
keratins which have wide applications in different fields. Due to the increasing production of …

The search for novel renewable products over synthetics hallmarked this decade and those
of the recent past. Most economies that are prospecting on biodiversity for improved bio …

Feathers account for 5–7% of the total weight of chicken have become one of the major
pollutants due to their recalcitrant nature. Feather which is constituted of 90% keratin can be …

Keratinases belong to a class of proteases that are able to degrade keratins into amino
acids. Microbial keratinases play important roles in turning keratin-containing wastes into …

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

Enormous masses of keratinous wastes are annually accumulated in the environment as
byproducts of poultry processing and agricultural wastes. Keratin is a recalcitrant fibrous …

Keratin is regarded as the main component of feathers and is difficult to be degraded by
conventional proteases, leading to substantial abandonment. Keratinase is the only enzyme …

The environment is under constant threat due to the huge accumulation of the keratinaceous
wastes produced by poultry processing industries and poultry farms. Millions of tons of …

Keratinase are proteolytic enzymes which have gained much attention to convert keratinous
wastes that cause huge environmental pollution problems. Ten microbial isolates were …

An effecient feather-degrading bacterium was isolated from poultry dumping yard and
identified as Bacillus pumilus GRK based on 16 S rRNA sequencing. Complete feather …
