title: [Formation of iron-binding metabolites by bacteria of the Enterobacteriaceae family].
abstract: The capacity of Enterobacteriaceae strains cultivated in a synthetic medium for the biosynthesis of catechols and hydroxamates has been studied. Among the strains under study all strains of the genera Salmonella (8 strains), Escherichia (102 strains), Citrobacter (5 strains), Enterobacter (2 strains), Serratia (1 strain) synthesize catechols. In the genus Shigella (128 strains) all Sh. flexneri serovars (79 strains) do not synthesize catechols, other representatives of this genus synthesize iron-fixing metabolites The synthesis of catecholsin the pathogenic Escherichia serovars is 1.5-2 times lower than in the non-pathogenic and opportunistic enterobacterial strains. Among the representatives of the genus Klebsiella (82 strains) catechols are synthesized by Kl. pneumoniae (68 strains) and not synthesized by kl. rhinoscleromatis (5 strains) and Kl. ozaenae (9 strains). Catechols are not synthesized also by all Proteus organisms under study (12 strains). All the enterobacteria under study show no capacity for the accumulation of hydroxamates under the conditions of catechol synthesis. The intensity of the synthesis of catechols depends on the composition of the medium and the conditions of cultivation.
