Method of producing optically active amino acid

摘要

A method of producing an optically active amino acid is disclosed which comprises converting a mixture of an amino group-containing compound, e.g., an alkanediamine, and fumaric acid into an optically active amino acid by the action of a microorganism. The method is useful in industrially producing an optically active amino acid from the inexpensive starting materials, i.e., fumaric acid and an amino compound, under mild conditions of ordinary temperature and ordinary pressure.
