참여 물질

반응 단계

The reaction solution (250 g) containing 36 weight % (wt %) of L-phenylalanine, a bacterial cell (in an appropriate amount) of MT-11046 produced in Example 1 and water was reacted at 25 degrees centigrade for 24 hours or more. During the reaction, pH of the reaction solution was adjusted to each pH shown in Table 3 with 25% ammonia water. A solid of (S)-β-phenylalanine precipitated under all examined conditions was observed. The reaction yields of (S)-β-phenylalanine in respective pHs are shown in Table 3.
