Abstract

A microorganism is described which is transformed with DNAs which encode a hydantoinnase, a racemase, and a carbamoylase. As a result, the microorganism is able to degrade hydantoins directly to amino acids. A process for the production of the microorganism and a process for producing amino acids with the microorganism is also described.
