Figure 2

Metabolic product distribution for E. coli K24KP growing on glucose or glycerol at 125 or 500 rpm. Final concentrations of the metabolic products (PHB, ethanol, acetate, formate and lactate) assayed in 24-h bioreactor cultures are shown as a function of the different carbon sources and agitation conditions used. The ethanol to acetate ratio, that reflects the internal redox state of the cells, is also shown.
