Figure 5. Relation between glucose and RF consumption.

(A) Chronoamperogram recorded at −0.25 V vs. Ag/AgCl, 2000 rpm, 150 μM RF, 5 × 10⁷ cells.mL⁻¹ F. prausnitzii, in absence of glucose initially; arrows represent small additions of glucose, Δj_la is the increase in current density subsequent to glucose addition (example represented for a 13.8 μM addition). (B) Corresponding RF reduced per glucose consumed.
