| titleOfInvention | Method for producing D-cysteine hydrochloride through combination of enzyme method and membrane technology |
| abstract | The present invention discloses a method for producing D-cysteine hydrochloride through combination of an enzyme method and a membrane technology, and belongs to the field of amino acid production. According to the method, a fermentation tank, a first filtration membrane, a chemical reaction kettle, a second filtration membrane, an oxidation crystallization tank, an electrolysis cell, a crystallization kettle, a drier and a crusher are adopted as equipment, and a concentrated tryptophanase culture liquid, pure water, a DL-cysteine hydrochloride powder agent, indole, active carbon, a sodium hydroxide aqueous solution and hydrochloric acid are adopted as raw materials to produce D-cysteine hydrochloride. According to the present invention, the common equipment is used, the production efficiency is high, the conversion time is short, and especially the two-stage membrane filtration is added, such that the product purity is substantially improved, the product achieves the medicine-grade through the improvement of the purity, and the sale price is substantially increased. |
