Studies were made on the influences of Na^+, K^+ and NH_4^+ on the respiratory metabolism of glutamate in B. aneurinolyticus and the following results were obtained. The respiratory metabolism of glutamate in a tris-phosphate buffer solution was hastened by adding Na^+, K^+ or NH_4^+, and a combined addition of Na^+ and K^+ enhanced the respiration to the highest level. The respiratory metabolism of α-ketoglutarate was considerably enhanced by an addition of K^+. When NH_4^+ was added with K^+, the respiration was remarkably enhanced, whereas a single addition of NH^+_4 exerted an inhibitory effect. The metabolism of pyrrolidone carboxylate was promoted by the single or combined addition of K^+ and Na^+. K^+ was more effective than Na^+. The metabolism of succinate was strikingly hastened by K^+. However, Na^+ was not effective on the respiration.
