Two-Component Signal Transduction System SaeRS Positively Regulates Staphylococcus epidermidis Glucose Metabolism

Figure 6

pH value of S. epidermidis 1457 in BM medium containing various concentrations of glucose. SAE, WT and SAEC were grown with or without 0.125%, 0.25%, 0.5%, and 1% (g/mL) glucose for 24 h. Then, the cultures were centrifuged. The pH of the supernatant was determined by using a pH meter (FE20, Mettler-Toledo, Shanghai, China).
