title: Effect of streptomycin on some enzyme systems of Bacillus subtilis.
abstract: Streptomycin slightly inhibited lactic and malic dehydrogenases of Bacillus subtilis, and inhibited isocitric dehydrogenase to about 60%. The formation of lactic dehydrogenase, glutamic dehydrogenase, alpha-alanine dehydrogenase, and succinic dehydrogenase was stimulated by the antibiotic at a concentration causing 50% inhibition of bacterial growth. Streptomycin had practically no influence on the formation of malic dehydrogenase, but the antibiotic produced 48% inhibition of the synthesis of isocitric dehydrogenase.
