Major enzyme activities on solid biomass degradation. Cellobiohydrolase (a) and β-glucosidase (c) are the major hydrolases and cellobiose dehydrogenase (b) the major oxidase secreted by M. thermophila during growth on SCBIN (closed circles) “in natura” as well as SCBDL (shaded circles) delignified and SCBSE (open circles) “steam exploded” biomass. Other oxidative enzymes laccase (d), lignin peroxidase (not shown) and Mn-peroxidase (not shown) were detected at very low levels
