Influence of NaCl at pH 4 and 37°C: cyclic voltammogram of O2 reduction by B. pumilus BOD at 5 mV.s−1 in 200-100 mM phosphate-citrate buffer. Blue curve: usual catalytic response in the absence of NaCl. Red curve: hysteresis observed after 15 mM NaCl addition. The arrows indicate the direction of the potential sweep. The pyrolytic graphite electrode was first modified with carbon nanofibers and then with BOD.
