Fig. 4From: Insights into the keratin efficient degradation mechanism mediated by Bacillus sp. CN2 based on integrating functional degradomicsIn vitro detection of the effect of reducing agents on the feather hydrolysis by keratinase. Na2SO3 and DTT were used as reducing agents. Cell-free fermentation broth at 72 h was collected and used as a crude enzyme for hydrolyzing feather keratinBack to article page
