RESUMO

Campbell, J. N. (American Meat Institute Foundation, Chicago, Ill.), James B. Evans, Jerome J. Perry, and C. F. Niven, Jr. Effect of ammonium ion on growth and metabolism of Micrococcus sodonensis. J. Bacteriol. 82:823–827. 1961.—When Micrococcus sodonensis was grown in a synthetic medium deficient in ammonia, large quantities of α-keto acids, chiefly α-ketoglutaric, accumulated in the medium. The addition of ammonium chloride to this medium prevented such accumulation and also supported increased growth, even in the presence of excess glutamate. Neither potassium nor sodium would substitute for ammonia in producing this effect.
