Fig. 4From: Comprehensive insights into the mechanism of keratin degradation and exploitation of keratinase to enhance the bioaccessibility of soybean proteinSulfite metabolism for the groups 0Â h VS 8Â h and 8Â h VS 20Â h when Bacillus sp. 8A6 grew in feather medium. Meanwhile, the group 0Â h VS 8Â h meant the comparisons of gene expression between 0 and 8Â h. The group 8Â h VS 20Â h meant the comparisons of gene expression between 8 and 20Â h. The up-regulated and down-regulated genes are indicated as red and blue color, respectivelyBack to article page
