実験手順

To a 15-mL polypropylene centrifuge tube was added 3.78 mL of 50 mM potassium phosphate buffer (pH 7.0), 1.0 mL of a suspension of 22.1 mg dry cell weight E. coli SW132 wet cells (prepared as described in Example 10) in 50 mM potassium phosphate buffer (pH 7.0), and 0.2381 g of 2-furancarbonitrile. The final concentration of 2-furancarbonitrile was 0.506 M. The reaction mixture was mixed on a rotating platform at 23° C. After 30 min, 7.50 mL of 95:5 acetonitrile/water containing 0.30 M N,N-dimethylbenzamide (HPLC external standard) was added to the reaction, the resulting mixture centrifuged, and a 0.100 mL of the supernatant mixed with 0.900 mL of acetonitrile and analyzed by HPLC. The conversion of 2-furancarbonitrile was 100%, and the yields of 2-furancarboxamide and 2-furancarboxylic acid were 99% and 0%, respectively.
