L-Alanine crystal with the same optical purity ([α]_D²⁵=+1.98)as that of the seed L-alanine cry stal has been obtained from saturated solution of DL-α-alanine by seed crystal resolution method. Addition of surfactant (OP series) in culture fluid accelerated the crystallization of L-alanine.
- alanine optical isomer,
- resolution,
- seed crystallization,
- surfactant
