Trisodium Phosphate → Trisodium Phosphate

Temperature

30 °C

Each of the microorganisms listed in Table 1 was planted in 50 ml of a medium containing 1% of glucose, 0.5% of peptone, and 0.3% of yeast extract, and was shaking-cultured for 48 hours at 30° C. The culture medium was centrifuged to obtain the cells, which were then put into a test tube and suspended with 1 ml of 1 M sodium phosphate buffer solution (pH 7.0) added thereto. With 1 mg of dl-2-methylaminopropiophenone hydrochloride added thereto, the mixture was shaken for 24 hours at 30° C., so as to effect a reaction. After the reaction was completed, the reaction mixture was centrifuged, so as to remove the cells, and the supernatant was subjected to HPLC (μBondapakphenyl, manufactured by Waters Corporation, with a diameter of 4 mm, a length of 300 mm, an eluent of 0.05 M sodium phosphate buffer solution (containing 7% of acetonitrile), pH 5.0, a flow rate of 0.8 mL/min, and a detection wavelength of UV 220 nm), thereby yielding an optically active pseudoephedrine.
