Determination of electron shuttling properties of PSM. (ae) The cyclic voltammograms (CV) of different PWE was performed without addition of microbes, which illustrated both oxidation and reduction peaks. The closed-loop area was estimated from the CV curves (V. mA), in the order Mentha (4.2) > Leucaena (3.9) > Terminalia (3.7) > Eucalyptus (2.2) > Psidium (2.1). Graphs are plotted by using NOVA 1.11 software (https://metrohm-autolab.com/Products/Echem/Software/Nova.html) and Origin 9.0 software (https://www.originlab.com/).
