Method Abstract: "Batch cultures of Escherichia coli were grown in minimal media supplemented with various carbon sources which supported growth at specific growth rates from 0.2 to 1.3/h. The respiration rates of the cultures were measured continuously."
Comments P.118 right column 2nd paragraph: "The varying growth yields thus agree with the observation that QO2 is, for most cultures, approximately 20 mmol/h per g(dw), independent of growth rate. The oxidation-reduction state of the substrate influenced the growth yield. In other words, reduced substrates gave higher yields and oxidized substrates gave lower yields."
