Comparison of the effect of fermentation with native C. thermocellum pfors (strain LL1319) or T. saccharolyticum pforA (strain LL1570). Substrate utilization as residual cellulose (light blue) and cells by pellet nitrogen (orange) versus fermentation times for strains LL1319 (a) and LL1570 (b). Major fermentation products—ethanol (red), acetate (dark blue), lactate (light blue), formate (light green), glucose (gray), isobutanol (purple), and extracellular amino acids (yellow) from the same fermentation runs for strains LL1319 (c) and LL1570 (d). Error bars represent mean absolute deviation (n = 2 fermentations). The data shown is for representative fermentations. Data for additional replicates is presented in Additional file 1: Table S5 and Figure S3. See Additional file 3 for tabular presentation of the data
