Abstract

PURPOSE: To prevent the decomposition of raw material serine in a reaction solution containing an enzyme capable of decomposing the serine, by the presence of a specific amount of ammonia ions in the reaction solution containing the serine.
CONSTITUTION: Ammonia ions in a concentration of 0.1mol/l or more and 2mol/l or less, are present in an aqueous solution containing L-serine, D-serine or DL-serine in the presence of a cultivated microorganism containing an enzyme capable of decomposing the L-serine and (or) D-serine or an extract from the cultivated microbial cell, e.g. the genus Escherichia, Pseudomonas or Proteus. Various inorganic or organic ammonium salts, e.g. ammonium chloride, ammonium sulfate, ammonium phosphate or ammonium carbonate, are used as the compound to give the ammonium ions.
