| Abstract: | As a hot-spot of biological dehairing,keratinase is specific to degrade keratin,which resulted in the reduction of damage to collagen and improvement of the quality of resultant leather.But the mechanism still remains.Bacillus strains which exhibit keratinolytic activity screened was applied to the process of dehairing to establish the producing-clear of the leather and also to explore the mechanism.One-variable-at-a-time approach was utilized to optimize dehairing conditions and the dehairing mechanism by ... |
