Abstract
A new microbiological process for the production of hydroxy-nitrogen-heterocyclic-carboxylic acids or their soluble salts of the general formula: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and each is a hydrogen atom, a halogen atom or a C.sub.1 -C.sub.4 alkyl group and X is a nitrogen atom or a CR.sub.3 function, wherein R.sub.3 is a hydrogen atom or a halogen atom, starting from the corresponding nitrogen-heterocyclic-carboxylic acids, as well as new microorganisms suitable for use in the process.
