This was relatively close to the glucose consumption
rate of the culture with reference medium, which
was 3.5 g/[L · d] (Table 1A), although a slight inhibition
was observed at concentrations of 1.0 and 1.5 mM coniferyl
aldehyde. At 2.0 mM coniferyl aldehyde, the glucose
consumption rate dropped drastically to 0.45 g/[L · d].
