Identification of putative inulin utilization loci in the inulin responder Bacteroides genomes IMSAGC_001 and IMSAGC_004. a Polysaccharide utilization loci (PUL) from reference Bacteroides species, IMSAGC_001, and IMSAGC_004. Common predicted functions are color-coded while intervening unrelated genes are in gray. Signal peptide, SP; glycoside hydrolase, GH; polysaccharide lyase, PL. b Heat map of the identities of amino acid sequences in PUL genes between inulin responder (001 and 004) and non-responder (006 and 014) Bacteroidales and the known inulin utilizer B. ovatus. c, d Phylogenetic analysis of glycoside hydrolase (c) and a concatenated sequence containing SusC and SusD (d) between reference Bacteroides species, IMSAGC_001, and IMSAGC_004. IMSAGC_001 and IMSAGC_004 are indicated with black circles
