Effects of NaN₃ on the growth, extracellular electron transfer and metabolic activity of P. putida F1 in aerobic shaking flasks and the BES. A) growth inhibition effects of 3 mm NaN₃ on P. putida F1 in DM9 medium determined using BioLector cultivation system. The coloured lines were averaged from 4 biologic replicates (shown in light grey lines in the background) for each condition. B) interruption test of NaN₃ on the performance of BES reactor. P. putida was inoculated at time 0. C) glucose consumption and product profile of the BES reactor corresponding to the conditions described in B). Extracellular concentrations were measured.
