NEW METHOD FOR PRODUCING BETA-BONDED POLYASPARTIC ACID AND BETA-BONDED POLYASPARTIC ACID PRODUCED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a β-bonded polyaspartic acid, its salt or ester in high purity. SOLUTION: The invention provides a method for synthesizing a β-bonded polyaspartic acid, its salt or ester in high purity by using a polyaspartic acid hydrolase in an organic solvent and using aspartic acid, its salt or ester as a substrate.
