Fig. 6From: Insights into the keratin efficient degradation mechanism mediated by Bacillus sp. CN2 based on integrating functional degradomicsTranscriptome and proteome analysis of keratin-degrading enzyme components. a The expression levels of key proteases were detected by RT-qPCR. b Heat map comparison of the expression patterns of selected proteases detected in the secretomes of Bacillus sp. CN2 during growth on feather keratin at 6, 12, 24, 36, 48, 60, and 72 hBack to article page
