| titleOfInvention | A kind of method of Production by Enzymes l-tyrosine |
| abstract | The invention discloses a kind of methods of Production by Enzymes l-tyrosine, comprising: produces pyruvic acid using fermentation method, beta-Tyrosinase, phenol and NH is added in the pyruvate fermentation later period 4 The conversion of pyruvate of generation is l-tyrosine, obtains the fermentation liquid containing l-tyrosine by Cl；The fermentation liquid containing l-tyrosine is taken, is heated to 70 DEG C -90 DEG C, acid adding to l-tyrosine crystal is completely dissolved；Active carbon is added to decolourize, ceramic membrane filter is first used after decoloration, removes thallus, albumen and active carbon, gained clear liquid carries out second through acidproof liquid cartridge filter again and filters；Second of filtered clear liquid adjusts pH to 5.0-7.0, and decrease temperature crystalline, centrifugation obtain l-tyrosine.This invention simplifies techniques, improve production efficiency, gained l-tyrosine purity is high, high income, and the purity of obtained tyrosine significantly improves than traditional extraction method, reaches 98.0% or more, meet every tyrosine drug standard. |
