FIG 2.

Growth and carbon source degradation curves of Cupriavidus pinatubonensis JMP134 grown on binary mixtures of aromatic compounds and the corresponding carbon source degradation in the respective single-compound cultures. Except for phenol (2 mM), all aromatic compounds were tested at 5 mM in single-compound and binary-mixture cultures. Note that the final growth yields reflect different amounts of added carbon. Open and closed symbols represent substrate removal in cultures grown with single compounds and binary mixtures, respectively. Dashed lines represent growth levels in binary mixtures, determined by OD₆₀₀ measurements. Plots show representative curves from 4 to 6 biological replicates. Standard deviations of technical replicates were lower than 5% and are not shown for clarity.
