Functional Diversity of Carbohydrate-Active Enzymes Enabling a Bacterium to Ferment Plant Biomass

Figure 2

mRNA expression of all 171 CAZymes during growth on pectins A–C, hemicelluloses D–E, glucans F–H, and raw corn stover I relative to expression on glucose.

Expression was quantified as log2(RPKM) with significantly differentially expressed genes on a given polysaccharide shown as triangles and unchanged genes as circles. The 56 purified CAZymes are red and others are blue.
