text: In the isolation of cysteine from the cysteine-containing reaction solution obtained by the fermentative method, the enzymatic method, the synthetic method, or any other method (hereinafter the term "reaction solution" shall mean the solution which exists after completion of the reaction of the enzymatic, fermentative, or synthetic method), since the composition of the reaction solution is complicated and the solubility of cysteine in water is very high, there have preveiled various methods which effect isolation and purification of cysteine by preliminarily causing the cysteine to react with a strong acid such as hydrochloric acid or p-toluene sulfonic acid thereby forming a corresponding salt.
