Composition and diversity of the carbohydrate-active enzymes (CAZyme) in each MAG across the microbial taxa. A Boxplots showing the total CAZy gene count per MAG within each phylum (green) and the CAZyme functional diversity (i.e., number of CAZy families per MAG; red). The boxplots indicate the median values as well as the lower and upper quartiles, and the numbers in brackets on the y-axis denote the MAG count. All the CAZymes belonging to the AA, CBM, PL, CE, GH, and GT classes were considered. B Distribution of CAZymes across the MAGs of six major bacterial phyla. AA, auxiliary activities; CBM, cellulose-binding motifs; CE, carbohydrate esterases; GH, glycosyl hydrolases; GT, glycosyltransferase; and PL, polysaccharide lyases
