Procedure
A 5.0 mL suspension of 0.500 g (wet cell paste) E. coli SS1001 cells (ATCC PTA-1177) in 50 mM potassium phosphate buffer (pH 7.0) was added to a mixture containing 4.80 mL of 50 mM potassium phosphate buffer (pH 7.0), 80.5 mg of (E)-2-methyl-2-butenenitrile (100 mM final concentration of (E)-2-methyl-2-butenenitrile), and 80.7 mg of (Z)-2-methyl-2-butenenitrile (100 mM final concentration of (Z)-2-methyl-2-butenenitrile), and the resulting suspension stirred at 35° C. Samples (0.100 mL) were mixed with 0.900 mL of 60 mM N-ethylacetamide (HPLC external standard) in 1:1 acetonitrile:methanol, the resulting mixture was mixed, centrifuged, and the supernatant analyzed by HPLC for (E)- and (Z)-2-methyl-2-butenenitrile and (E)- and (Z)-2-methyl-2-butenoic acid. After 6 h, the conversions of (E)-2-methyl-2-butenenitrile and (Z)-2-methyl-2-butenenitrile were 100% and 0%, respectively, and the yields of (E)-2-methyl-2-butenoic acid and (Z)-2-methyl-2-butenoic acid were 99% and 0%, respectively.
