Monoculture solubilization at two pH levels. Fractional carbohydrate solubilization for 7-day Clostridium thermocellum monoculture fermentations of 80 g/L senescent switchgrass and corn stover at pH 6.5 and pH 7.0. The statistical analyses were performed using t-tests for two-samples assuming unequal variance, and the results are available as supplemental file 3
