title: [Synthesis of aspartate decarboxylase in Escherichia coli strains].
abstract: The ability to synthesize intracellular aspartate decarboxylase was investigated in 19 E. coli strains, out of which strain AB 2472 proved most effective. The maximum accumulation of the enzyme was seen after 6-hour cultivation at pH 6.0, t = 37 degrees C and 4% DL-aspartate used as inducer. By thin-layer chromatography on silufol it was demonstrated that the product of aspartate decarboxylation was beta-alanine.
