the early stage, voltage growth is slow because of three reasons: low
bacteria population and the bacteria are trying to acclimatize to the
cell environment; presence of high concentration of electron acceptors;
limited colonization of the anode surface by bacteria. For this reason
during the early stage, every time agitation was done on the cells a foul
smell was expelled from the cells (as Equation 1). The degree of the
stench decreased with time from day 0-3. On day 4, there was no more
