Fig. 2From: Declining carbohydrate solubilization with increasing solids loading during fermentation of cellulosic feedstocks by Clostridium thermocellum: documentation and diagnostic testsFermentation products and residual solubilized carbohydrates at various solid loadings for monocultures of Clostridium thermocellum. Panels A corn stover and C senescent switchgrass fermentation products ethanol, acetate, formate, and lactate. Panels B corn stover and D senescent switchgrass residual xylose, arabinose, and glucose in the fermentation broth quantified in monomeric form via mild acid hydrolysis of the supernatant. Error bars represent 1 standard deviation for all datapoints in all panels (n = 2)Back to article page
