| titleOfInvention | Production of d-alanine |
| abstract | PURPOSE: To obtain D-alanine in an economically advantageous way by acting D-amino acid transaminase on DL-aspartic acid in the presence of a small amount of pyruvic acid to form D-alanine. n CONSTITUTION: D-amino acid transaminase is acted on DL-aspartic acid as a substrate of 50-1,000(pref. ca. 200)mM concentration in the presence of pyruvic acid of 0.1-10(pref. ca. 1)mM concentration to produce D-alanine. Thence, the resultant liquid reaction product is freed from protein by e.g. trichloroacetic acid followed by eluation of D-alanine through cation exchange chromatography and then crystallization by isolelectric point precipitation to collect the objective D-alanine. Preferably, the reaction temperature is 25-60°C, pH 5-9, reaction time 4-48hr. n COPYRIGHT: (C)1989,JPO&Japio |
