Substrate utilization and DAHP production by resting cells of strain PB12 PTS^-Glc⁺aroB^- (pRW300aroG^fbr pCLtktA). Resting cells were incubated with the different carbohydrates in the conditions described in Methods. Carbon utilization and the production of DAHP were measured at different times after the addition of the carbohydrates. Mean values from two independent experiments are shown; differences between values in these experiments were <10%. The biomass value for the glycerol-glucose mixture was approximately 0.66 g/L, whereas for the rest of the carbon sources was 1.064 g/L (data not shown).
