FIGURE 4.

Growth phenotypes of S. oneidensis MR-1 ΔhexR mutant on various carbon sources. Cells were grown in the minimal medium containing 10 mm N-acetyl-d-glucosamine (GlcNAc) or 20 mm glycerate, lactate, and pyruvate as the sole carbon source. The cell growth was monitored by measuring the absorbance at 600 nm.
