PURPOSE:To isolate an L-amino acid and flocculate and remove a microorganism at the same time, by treating a solution of the L-amino acid prepared by using the microorganism with an H type strongly acidic cation exchange resin. CONSTITUTION:A reaction solution, containing an L-amino acid and a microorganism, and prepared by using the microorganism is passed through a layer of an H type strongly acidic cation exchange resin to adsorb the L-amino acid on the cation exchange resin and flocculate and stick the microorganism onto the cation exchange resin at the same time. Water is then pssed through the cation exchange resin to wash away the flocculated and stuck microorganism by the back washing. The L-amino acid is then eluted with aqueous ammonia, etc. |
