Fig. 5. Assessment of organismal fitness by measurement of oxygen consumption. (a) Respirometry curves of S. oneidensis MR-1 control (unadapted) cultures exposed to control conditions (purple), 25 mg L^–1 NMC (orange), and 25 mg L^–1 NMC ion eq. (green) in Passage E. (b) Respirometry curves of NMC-adapted cultures exposed to control conditions (purple), 25 mg L^–1 NMC (orange), and 25 mg L^–1 NMC ion eq. (green) in Passage E. (c) Respirometry curves of ion-adapted cultures exposed to control conditions (purple), 25 mg L^–1 NMC (orange), and 25 mg L^–1 NMC ion eq. (green) in Passage E. Error bars represent the standard deviation of replicates. Representation of this figure without standard deviations is located in Fig. S7.† .
