During the advanced voltage rise stage, there was an in-crease
in the bacteria community responsible for the generation of voltage.
The steady increase is a factor which is also increased by the bacterial
community forming a film/colonizing the anode surface. The
stationary phase is of maximum constant voltage. Since the voltage
developed entirely depends on bacteria community responsible for
voltage development between the anode and cathode; the voltage at this
phase is constant since the bacterial community responsible for voltage
development is at a constant population. The constant population
signifies that the number of bacteria dying is equal to the number that
is being reproduced. During this stage, the food available can only
sustain a constant bacterial population. The constant population was
