To clarify the major factor caused by oxygen-enhancing charge production of Shewanella decolorationis NTOU1 towards a polarized anode, a series of experimental runs (i.e., with/without ambient air flushing and with/without ammonia addition as nitrogen source) were conducted in this study. Within 6-day of operation at +0.4 V vs. Ag|AgCl and starting with 35 mM of lactate, consistently the electrical charge production under the aerobic condition was higher than that under the anaerobic condition. In all the experimental runs, the values of nicotinamide adenine dinucleotide (NADH) production were found to be correlated positively and significantly with the charge production, but the highest Cou..View full abstract
