title: [The characteristics of the regulation of lysine biosynthesis in Streptococcus bovis].
abstract: The effect of threonine and methionine on the growth of and lysine synthesis in Streptococcus bovis st. A024/85 was studied. The character and the degree of manifestation of growth and regulation effects of these amino acids depend on their contents in the fermentation medium. The target in the regulation of lysine biosynthesis is aspartate kinase, whose synthesis is controlled by threonine and methionine. Lysine excretion was stimulated by the addition of a low concentration of dimethylsulfoxide in the medium during fermentation.
