Effects of the kdpD460 and rseP98 mutations on the viability and on the metabolic activity of strains incubated in monoculture. Strains were inoculated 1:500 (time zero) into Pi-limiting medium, further incubated, and the numbers of CFU (a, b) in the cultures, the pH (c, d) and the concentrations of glucose (e, f) and of acetate (g, h) in the spent media were determined
