Fig. 1From: Declining carbohydrate solubilization with increasing solids loading during fermentation of cellulosic feedstocks by Clostridium thermocellum: documentation and diagnostic testsFermentation of corn stover and senescent switchgrass by monocultures of Clostridium thermocellum at various solid loadings (n = 2). A Fractional carbohydrate solubilization with error bars representing 1 standard deviation shown (n = 2).
