Abstract
L-cysteine-is separated from an L-cysteine-containing fermenter broth containing an oxidizing agent which is capable of oxidizing L-cysteine at pH<5, by contacting the L-cysteine-containing fermenter broth with an ion exchanger at a pH from 5 to 9, the pH in the fermenter broth becoming <5, and preferably <2. The L-cysteine binds to the ion exchanger and the bound L-cysteine is then removed from the ion exchanger by means of an eluant.
