Effect of dilution rate on fermentation characteristics of wild type E. coli.

Dilution rate (h^−1)	Biomass conc. (g/L)	Specific glucose uptake rate (mmol/g/h)	Specific acetate formation rate (mmol/g/h)	Biomass yield (g/g)	Specific CER (mmol/g/h)
0.2	1.45±0.06	3.07±0.13	ND*	0.37±0.015	9.15
0.4	1.87±0.09	4.75±0.23	0.01	0.47±0.023	11.61
0.6	2.0±0.09	6.67±0.3	0.88±0.04	0.5±0.023	13.17
0.7	1.93±0.08	8.05±0.34	1.33±0.06	0.48±0.02	15.83

*ND: not detectable, where glucose detectable limit is 0.038 g/L.
