Abstract
In the recent time more work is considered in bioelectrochemical system for
obtaining power and wastewater treatment. In these systems many microbes are
used to carry out the electron transfer from medium to the anode electrodes. These
microbes are called electrogen since they have the capacity to transfer these
electrons. The main group comes under Geobacter species that provide the high
strength to these microbes. The initial source of anaerobic culture is conventional
wastewater treatment plants and sludge is collected and used in the anodic
chamber of microbial fuel cell (MFC). For improving the performance of MFC,
the lag phase of the system needs to be reduced and more current research are
going on for understanding of biofilm formation of anode electrode and transfer
of their electron to the anode electrode.

Introduction
In the past decade the bioelectrochemical system (BES) is emerged as a novel
technology for wastewater treatment and high value chemical production. There
are many groups in this category those are developed for the wastewater treatment
and bioelectricity generation. The microbial fuel cell (MFC) is the most studied
bioelectrochemical system for wastewater treatment and bioelectricity generation. In
these in the starting stage only synthetic wastewater was used and at later stage real
