摘要： The invention relates to a method for producing a purified solution containing L-cysteine from a fermentation broth containing L-cysteine. In said method, the fermentation broth containing L-cysteine, at a pH value from pH 6 to 9, is brought in contact with a basic anion exchanger, wherein the L-cysteine bonds to the anion exchanger. The anion exchanger is then rinsed with a first washing solution, and the bonded L-cysteine is removed from the anion exchanger by means of an acid and transferred into an eluate. Said eluate, having a pH≦4, is brought in contact with an acidic cation exchanger, wherein the L-cysteine bonds to the cation exchanger. The cation exchanger is rinsed with a second washing solution, and the bonded L-cysteine is removed from the cation exchanger by means of a strong acid.
