a Substrate-binding surface in the modeled structures of the AA9 subfamily in C. thermophilum. Three regions (depicted by black, red and yellow arrows) define the immediate environment of the catalytic center. b Schematic diagram representing the synergistic lignocellulose degradation mode of C. thermophilum. Solid boxes indicate the enzyme genes that were detected in the secretomes of C. thermophilum. A greater saturation of the color of the box indicates more expression of the proteins, and vice versa. Blue and purple arrows indicate the degradation of xylan, and red arrows indicate the degradation of cellulose; the purple dotted line represents that arabinose hardly enters the HMP pathway. The green solid arrow indicates direct electron transfer, and the yellow dotted arrow indicates indirect electron transfer
