Enzymatic dehairing: A comprehensive review on the mechanistic aspects with emphasis on enzyme specificity.

Enzymatic dehairing as a part of the efforts for greener leather processing has reached progressive advancement with the tradition-bound tanning industry being now more receptive to cleaner processing methods due to increasing pressure from environmental groups. The dehairing mechanism is vaguely understood at present from the point of view of the enzyme specificity, which is needed for consistent and satisfactory hair removal without deleterious effect on the leather quality. Gaining insight into the dehairing specificity would help in designing efficient dehairing process.

Alkaline protease from Bacillus cereus VITSN04: Potential application as a dehairing agent.

The objective of this work is to use protease enzyme as an ecofriendly alternative to chemicals in dehairing. An alkaline protease producing bacterium was isolated from protein-rich soil sample. The bacterium was identified as Bacillus cereus VITSN04 by 16S rRNA gene sequencing method.
