Keratinase production and keratin degradation by a mutant strain of Bacillus subtilis.

Journal of Zhejiang University. Science. B - 1 Jan 2008

Cai Cheng-gang, Lou Bing-gan, Zheng Xiao-dong

Abstract excerpt

A new feather-degrading bacterium was isolated from a local feather waste site and identified as Bacillus subtilis based on morphological, physiochemical, and phylogenetic characteristics. Screening for mutants with elevated keratinolytic activity using N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis resulted in a mutant strain KD-N2 producing keratinolytic activity about 2.5 times that of the wild-type strain....
