Reduction in the solubilization efficiencies of 17.5 g/L Avicel in fermentations containing 50% (v/v) spent supernatant. X-axis labels indicate the source of the spent supernatant from the first-round fermentation conditions used. Values in brackets above columns represent the molar ethanol production ratios (mM ethanol produced: mM glucose equivalents consumed). Avi Avicel, SG switchgrass
