ITROGEN CONTAINING HETEROCYCLIC CARBONIC ACIDS MICROBIOLOGICAL PROCESS FOR THE HYDROXYLATION OF N

摘要

A new microbiological process for the production of hydroxy-nitrogen-heterocyclic-carboxylic acids or their soluble salts of the general formula: (* CHEMICAL STRUCTURE *) I wherein R1 and R2 are the same or different and each is a hydrogen atom, a halogen atom or a C1-C4 alkyl group and X is a nitrogen atom or a CR3 function, wherein R3 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.
