| titleOfInvention | Production process of S-phenyl-L-cysteine |
| abstract | S-phenyl-L-cysteine can be produced in a high yield by reacting thiophenol and L-serine under the action of tryptophan synthase at a pH in a range of from 9.0 to 10.5. Purification of S-phenyl-L-cysteine obtained by this enzyme reaction can be effectively achieved by adjusting the pH of a crystal-containing reaction mixture to a strongly acidic level of 1.5 or lower to dissolve crystals of S-phenyl-L-cysteine, adding activated carbon to the pH-adjusted mixture, maintaining the resultant mixture at a temperature of from 20 DEG to 60 DEG C. under aeration with an oxygen-containing gas, subjecting the thus-obtained mixture to filtration, raising the pH of the resulting filtrate back to a range of from 2.5 to 6.0 to precipitate crystals of S-phenyl-L-cysteine and then recovering the thus-precipitated crystals.\! |
