Growth and carbon consumption of the ATCC 31831 (wild type) and D2281 (ΔrneG) strains. For the growth curve, overnight cultures of the wild type (filled circles) and the ΔrneG mutant (open circles) grown on CGC minimal medium containing 1% glucose were washed and then inoculated into fresh CGC minimal medium containing either 1% glucose (A) or 1% sodium acetate (B). Cell growth was monitored by measuring the OD₆₆₀. The consumption (filled triangles, ATCC 31831; open triangles, D2281) of glucose (A) and sodium acetate (B) was determined via an enzyme electrode glucose sensor and CE, respectively. All values are from at least three independent cultivations, and the error bars represent the standard deviations.
