The invention relates to novel micro-organisms which are able to utilise, as the sole nitrogen source, a guanidine valerianic acid derivative of the general formula (V), in which R<1> is hydrogen or hydroxy, and R<2> is a halogen atom or -NH2. It also relates to a novel enzyme with amidinohydrolase activity, and a novel process for preparation of D-proline derivatives from a L-arginine derivative. |
