Its growth rate was a sigmoidal function of Na+ concentration, being maximal and constant from 2 to 50 mm-Na+, and half maximal at about 0·5 mm-Na+. The relationship between cell concentration and Na+ concentration was non-linear; cell concentration increased abruptly when Na+ was greater than 0·3 mm. Accumulation of Na+ in the organism during growth was not detected. In the presence of K+, respiration was enhanced specifically by Na+. The respiration rate of the organism growing in the culture was a linear function of the growth rate when limited by the Na+ concentration, whereas the maximum rate induced by excess Na+ was independent of the growth rate.", }
