Expression of the Genes Encoding the Trk and Kdp Potassium Transport Systems of Mycobacterium tuberculosis during Growth In Vitro

Figure 5

The membrane potential values of  WT and trk-gene knockout strains at varying extracellular pH levels. The results represent nine replicates from three experiments represented as absolute fluorescence ± SEM. Statistical significance was determined in relation to membrane potential observed at pH 7 for each strain and between the strains at each pH level. .
