pH and NaHCO 3 effect on ebpA expression. OG1RF containing P ebpA ::lacZ was used in these experiments. Growth curves are represented in thin gray line for pH 7 aerobically, thin orange line for pH 7-Air/NaHCO3, dense gray line for pH 8 aerobically, and dense orange line for pH 8-Air/NaHCO3. All sets of cultures presented were analyzed concurrently. This figure is a representative of at least two experiments. A. OD600 nm readings. B. β-gal assays (β-gal units = OD420 nm/protein concentration in mg/ml).
