Figure 1.

Effect of carbon source on MIC of chromate for P. putida F1. Optical densities (OD₆₀₀) of F1 cultures after 48 h of growth in the presence of varying concentrations of chromate (K₂CrO₄) are shown. (A) F1 growth in LB broth. (B) F1 growth in M9 minimal media supplemented with 50 mM glucose (grey bars), 50 mM sodium lactate (white bars), or 67 mM sodium acetate (black bars) as the sole source of carbon. All cultures were grown in triplicate. Error bars denote the standard deviation of replicate measurements.
