Taxa contributing b-gus and gdh in fecal metagenomes of healthy individuals and CRC patients. Relative abundance of (a) phyla contributing b-gus, b proportion of Bacteroidetes and Firmicutes b-gus in healthy individuals and CRC patients (taxa contributing b-gus are listed in Additional file 1: Table S6), c taxa contributing gdh to the metagenomes of CRC patients and healthy individuals, d proportion of gdh of taxa with representatives E. hallii, B. obeum, F. plautii, and L. reuteri transforming PhIP in the presence of glycerol. Others, groups all taxa with low hits. ** indicates a significant difference at p < 0.01; *** indicates a significant difference at p < 0.001 with unpaired t-test
