Waste to Renewable Energy: A Sustainable and Green Approach Towards Production of Biohydrogen by Acidogenic Fermentation - Sustainable Biotechnology: Sources of Renewable Energy - page 140

Cyclic voltammograms (CV) obtained at acidic and neutral pH conditions visu-
alized well- defined redox pairs both in forward and reverse scans and the signal
corresponded to intracellular electron carriers, NADH/NAD + (E 0 , -0.32 V) [24]
(Fig. 3). Shuttling of H + between metabolic intermediates can be correlated to the
e - discharge observed in CV. At acidic pH, the e - discharge was almost similar at
