FIG 2.

Ethanolamine metabolism promotes UPEC growth in nitrogen-limited minimal medium and artificial urine medium (AUM). (A and B) Aerobic growth of selected UPECs at 37°C in ammonia-free modified M9 medium with glycerol (20 mM) (A) or in AUM (B). Hollow data points are without ethanolamine; solid data points are with an additional 10 mM ethanolamine. (C and D) Concentrations of ethanolamine (Eth), acetate, and ethanol over time during U1 growth in ammonia-free M9 medium with glycerol (20 mM) (C) and AUM (D), both of which were supplemented with an initial 10 mM ethanolamine. Values are the mean ± SEM (n ≥ 3).
