Abstract
A process for producing aromatic compound having at least one cyano group and one amide group or carboxyl group which process comprises subjecting aromatic polynitrile compound containing no carboxyl groups in a simple medium to the action of one or more microorganisms which have a nitrilase system capable of selectively hydrolyzing one cyano group of the polynitrile.
