Calcium affects the growth and survival of rhizobium meliloti

Abstract
The interaction of pH and calcium on the growth of acid-tolerant and acid-sensitive strains of Rhizobium meliloti and Tn5-induced acid-sensitive mutants of strain WSM 419 has been studied. The calcium concentration had only a minor effect on growth rate at alkaline and neutral pH, but it significantly influenced the behaviour of WSM 419 at acidic pH. Increasing the calcium concentration markedly stimulated the growth rate and allowed growth to occur at more acidic pH. Calcium affected the growth or survival of all seven strains of R. meliloti tested. Investigation of five Tn5-induced acid-sensitive mutants of WSM 419 indicated that four would grow even at pH 5.5 if high concentrations of calcium were added to the medium; the other would not grow at pH 5.6 or 5.5 even if 50 mM calcium was added to the medium.
