Fig. 6From: Biomass augmentation through thermochemical pretreatments greatly enhances digestion of switchgrass by Clostridium thermocellumClostridium thermocellum glucan solubilization and metabolite production after 7 days of fermentation on unpretreated and hydrothermal (HT), dilute acid (DA), dilute alkali (Alk), and co-solvent-enhanced lignocellulosic fractionation (CELF) pretreated switchgrass. Values on the arrows indicate the percentage of solubilized glucan that is unaccountedBack to article page
