^aP(3HB) produced from [1-¹³C₁]-glucose by 2-step cultivation.

^bMeans of ¹³C/¹²C ratio calculated from isotopomer abundances of the two fragments (m/z 45 and 87) derived from 3HB methyl ester.

^cDetermined from relationship between P(3HB) production and glucose consumption obtained by 6 ~ 8 independent 2-step cultivations for various incubation periods.
