Reaktionsschritte

Into a 10-mL volumetric flask was added 0.1271 g (1.00 mmol, 0.100 M) of cyanoacetic acid propyl ester, 9.689 mL of potassium phosphate buffer (50 mM, pH 7.0), and 0.20 mL of a 50 wt % cell suspension (0.10 g wet cell weight, 0.024 g dry cell weight) of Acidovorax facilis 72W (ATCC 55746) cells in 0.35 M potassium phosphate buffer (pH 7.0, previously heat-treated at 50° C. for 1h), and the resulting 10 mL suspension stirred at 25° C. Samples (0.180 mL) were mixed with 0.020 mL of 0.750 M N-methylpropionamide (HPLC external standard solution). The resulting solution was analyzed by HPLC. After 5 h, the conversion of cyanoacetic acid propyl ester was complete, and the yield (determined by HPLC and NMR) of propanedioic acid monopropyl ester was 100%, with no production of cyanoacetic acid or propanedioic acid.
