Abstract
Microorganisms of interest are capable of utilizing .alpha.-imino carboxamides, in the form of the racemate or of its optically active isomers, of the general formula ##STR1## wherein A together with --NH-- and --CH-- is an optionally substituted 5- or 6-membered saturated heterocyclic ring, as sole nitrogen source, and converting (RS)-.alpha.-imino carboxamides of Formula I into an S-.alpha.-imino carboxylic acid of the general formula ##STR2## These microorganisms are useful also for biconversion of an (RS)-.alpha.-imino carboxamide of Formula I into an S-.alpha.-imino carboxylic acid.
