  1. Values are expressed as carbon relative to the total amount of biomass carbon. The results shown are the averages of two cultures, measured 4 times. The wild type chemostat culture had a dilution rate of 0.17 ± 0.01 h-1; the ΔarcAΔiclR strain had a dilution rate of 0.33 ± 0.02 h-1. The carbon balance and redox balance for these experiments are similar to the data shown in Additional file 1
