Fig. 4

Fermentation addition tests. Panel A Fractional carbohydrate solubilization for 80 g/L corn stover with addition of cells (cellobiose-grown and centrifuged cell pellet), cellobiose solution, and suspended Avicel slurry at 48 h after inoculation versus a control (water only) or no addition (n = 2). Panel B Representative total gas production (cumulative CO2 and H2) for one of the duplicate reactors. Solubilization bars are averages of duplicate bioreactor runs, error bars represent 1 standard deviation. A single asterisk denotes a significance level of 0.1, and double asterisks denote a significance level of 0.05 between different runs as indicated in the figure. The statistical analyses were performed using t-tests for two-samples assuming unequal variance, and the results are available as supplemental files
