Abstract
The disclosure discloses a recombinantengineered bacterium capable of efficiently expressing keratinase, and belongs to the technical fields of genetic engineering and fermentation engineering. The disclosure successfully constructs a genetically engineered bacteriumWB600-pP43NMK-ker capable of efficiently expressing keratinase by using a keratinase gene from(BBE11-1) as a target gene, pP43NMK as an expression vector andWB600 as an expression host; and meanwhile, the disclosure conducts in-depth research on fermentation media and fermentation conditions when the engineered bacteria are configured as a production strain to produce keratinase to obtain a fermentation medium capable of increasing a yield of keratinase and an optimum process for fermentation production of keratinase.
