Abstract

Microbial fuel cell consisting two main components which are anode and cathode
materials. In the microbial fuel cell, both anode and cathode compartments are separated with a
separator. Anode generates the protons and electrons while cathode converts protons into water
with the presence electrons and oxygen. During the Microbial fuel cell operation, the
performance of anode is very crucial due to it provides the protons and electrons. Hence, the
high efficiency microbial fuel cell is very related with the high anode performance. This work
addressed to assess the enrichment process of electroactive bacteria (EAB) in anode of microbial
fuel cell. In this work, some parameters such as current generations, the reduction of chemical
oxygen demand (COD) content, and pH changes were used to assess the enrichment process of
EAB was reached. In addition, the presence of EAB on the anode surface was identified based
on the morphology of anode surface. The removal of COD and the pH value were determined by
using the American public health analysis method and pH tester, respectively. The morphology
of anode surface was analysed by using a scanning electron microscope. Whereas, current
generation was tested by using a mustimeter. The removal of COD and final pH were obtained
71.4 % and 5.7, respectively. The optimum current generation was observed 0.19 mA. The
surface morphology of anode before enriched with microbes was clear surface, while after
enriched with microbes was attached by microbes. The removal of COD, pH changes, current
generation and morphology of anode surface could be used to assess the EAB in the anode
compartment.
