Gene Ontology (GO) analysis of the molecular function, cellular component and biological process for the groups 0 h VS 8 h (A) and 8 h VS 20 h (B) according to the -log10(p-value) when Bacillus sp. 8A6 grew in feather medium. The higher −log10(p-value) indicates the more significant enrichment of the GO term. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of the pathways for the groups 0 h VS 8 h (C) and 8 h VS 20 h (D) according to the −log10(p-value) when Bacillus sp. 8A6 grew in feather medium. Meanwhile, the group 0 h VS 8 h meant the comparisons of gene expression between 0 and 8 h. The group 8 h VS 20 h meant the comparisons of gene expression between 8 and 20 h. The most significantly different pathways are shown according to the Q-value. Other significantly different pathways are shown in Additional file 1: Fig. S7
