“…Mediators are added to promote energy production in an MFC when bacteria cannot transfer electrons alone. 24 The reduced mediator is readily oxidized at the anode, and the oxidized form of the mediator shows favorable kinetics for reduction by the microbes. 25 The addition of mediators may influence the metabolic properties of organisms.…”

Microbial fuel cell (MFC) is a green technology and is an alternative energy resource of fossil fuels. MFC is the class of Bio-electro-chemical patterns with novel property, like wastewater treatment, electricity generation and biosensor operation. MFCs are ingenious devices that harness the power of bio-electrochemical processes to generate electric current by breaking down organic waste found in wastewater. These systems establish a fascinating connection between microbial metabolism and electricity production. The microbes within the MFCs thrive on the nutrients present in their environment and convert the energy stored in the organic matter into usable electricity. This electrical energy can be effectively utilized to power various essential portable electronic devices such as mobile phones, laptops, TVs, air dryers, threading machines, chargeable torches, as well as devices used in the air force, outer space, and weather stations. The maximum power produced by MFC using an Iron anode is 170 mW·m-2, 0.645 v, while MFCs have better power efficiency in mix culture Microbs 30 mA, 3,600 mW·m-2. It has been observed that MFCs equipped with carbon-based electrodes tend to have a longer lifespan compared to those using metal-based electrodes. However, one drawback of carbon-based electrode MFCs is that they generally exhibit lower power output. In recent times, the investment focus on MFC research has significantly improved the analysis of its chemical, microbiological, and electrochemical aspects. These advancements have led to notable enhancements in the sensing capabilities of MFCs. In this review, we have summarized the MFCs, their working principle, types, composition and the various factors which affect the performance of these MFCs.
