Ethanol and glucose concentrations (g/L) produced during SSF of CELF pretreated poplar solids by S. cerevisiae (D5A) at 37 °C (top layer) at glucan loadings of 11 (a), 15 (b), and 18 (c) wt% and K. marxianus (CBS 6556) at 37 °C (middle layer) at glucan loadings of 11 (d), 15 (e), and 18 (f) wt% and at glucan loadings of 11 (g), 15 (h), and 18 (i) wt% at 43 °C (bottom layer). All the experiments were conducted at an enzyme loading of 15 mg protein/per g glucan in raw poplar in a shake flask with a 25 mL working volume, in duplicates. Error bars indicated in the figure are standard deviation error bars among the duplicates
