TABLE 3.

Growth parameters of E. coli K-12 W3110 WT grown aerobically in M9 medium containing glycerol as C source and NH₄Cl or EA as N source

Medium	Physiological parameter
	µ	qS)glycerol	qS)ethanolamine	qP)acetate	qP)ethanol
M9 gly NH4Cl	0.44 ± 0.02	16.2 ± 1.6	ND	ND	ND
M9 gly EA B12	0.45 ± 0.01	14.7 ± 0.4	7.8 ± 0.3	1.7 ± 0.1	2.6 ± 0.1

^a The exponential growth rate µ is expressed in h⁻¹; the substrate uptake (q_S) and product formation (q_P) rates are expressed in mmol.g_DW⁻¹·h⁻¹·DW, dry weight; ND, not detected. Data are shown as mean (n = 3 biological replicates) ± standard deviation.
