Microbial fuel cells (MFCs) are an enticing environment friendly
technology that employs electrochemically active microbes
to convert organic materials into bioelectricity while causing no
environmental damage, therefore combating global warming
and energy scarcity. The present study’s objective is to produce
electricity using MFC and soil sludges. In both the presence
and absence of oxygen supply, the electrogenic capacity of bacteria
from different soil sludges, including river, agricultural, and
garden sludges, was examined. A two-chambered MFC is constructed
using an anode, a cathode, a proton exchange membrane,
and a salt bridge as its constituent parts. Several observations
indicate that this MFC may generate the maximum of up to 603
millivolts (0.603 volts) of electricity in the absence of an air
pump. The two common electrogenic bacterial strains that are
isolated from all the soil sludge samples are Clostridium spp. and
Geobacter spp. However, since the activity of the bacteria
gradually decreases and the voltage produced is not exceptionally
high, this experiment has the drawback that it does not
produce a voltage that lasts long. Although it has certain
challenges, an MFC is an alternative essentially a solution for the
renewable energy produced by bacterial activity that needs
additional consideration, research, and development. |
