Cellular biomass (a) and fermentation end-product (b) formation for five different cellobiose loadings at dilution rate of 0.1 h−1 for Clostridium thermocellum wild-type (LL1004) at steady state. Both cell yield and product formation have a linear relation with the amount of substrate utilized. Steady-state cell concentration is represented by both pellet carbon and pellet nitrogen, which both have a linear relation to cellobiose utilized. Error bars represent one standard deviation
