Biophotovoltaics is a relatively new discipline in microbial fuel cell research. The basic idea is the conversion of light energy into electrical energy using photosynthetic microorganisms. The microbes will use their photosynthetic apparatus and the incoming light to split the water molecule. The generated protons and electrons are harvested using a bioelectrochemical system. The key challenge is the extraction of electrons from the microbial electron transport chains into a solid-state anode. On the cathode, a corresponding electrochemical counter reaction will consume the protons and electrons, e.g., through the oxygen reduction to water, or hydrogen formation. In this review, we are aiming to summarize the current state of the art and point out some limitations. We put a specific emphasis on cyanobacteria, as these microbes are considered future workhorses for photobiotechnology and are currently the most widely applied microbes in biophotovoltaics research. Current progress in biophotovoltaics is limited by very low current outputs of the devices while a lack of comparability and standardization of the experimental set-up hinders a systematic optimization of the systems. Nevertheless, the fundamental questions of redox homeostasis in photoautotrophs and the potential to directly harvest light energy from a highly efficient photosystem, rather than through oxidation of inefficiently produced biomass are highly relevant aspects of biophotovoltaics.

“…The energy outcomes were 258 ± 10 mW/m 2 with 90% degradation rate of textile dyes after 24 h operation time of MFC. Sarma et al [114] explained the phenomena of composite polymer doped with magnetic nanoparticles on the anode to increase the dye's degradation rate and power output. The experimental data revealed that the removal efficiency was good which are near 90% and electricity generation found 4.9 ± 0.5 W/m 3 in the presence of polymer-coated magnetic composite electrode and Synechococcus sp.…”

A wide variety of pollutants are discharged into water bodies like lakes, rivers, canal, etc. due to the growing world population, industrial development, depletion of water resources, improper disposal of agricultural and native wastes. Water pollution is becoming a severe problem for the whole world from small villages to big cities. The toxic metals and organic dyes pollutants are considered as significant contaminants that cause severe hazards to human beings and aquatic life. The microbial fuel cell (MFC) is the most promising, eco-friendly, and emerging technique. In this technique, microorganisms play an important role in bioremediation of water pollutants simultaneously generating an electric current. In this review, a new approach based on microbial fuel cells for bioremediation of organic dyes and toxic metals has been summarized. This technique offers an alternative with great potential in the field of wastewater treatment. Finally, their applications are discussed to explore the research gaps for future research direction. From a literature survey of more than 170 recent papers, it is evident that MFCs have demonstrated outstanding removal capabilities for various pollutants.

“…[192] Although iron oxide/carbon composite anodes prepared by coating method possess an enhanced electron transfer, microbe attachment and power output, the catalyst degradation during a long operation may weaken the affinity and reduce the catalytic activity. [193,194] To strengthen the interaction of iron oxide and the carbon matrix, in-situ carbonization of the Fecontaining bacteria was adopted to synthesize heteroatomdoped FeO x /C composite anodes. The highly and covalently dispersed FeO x nanoparticles on rough surface enjoyed a good catalytic activity, significantly improving the power density from 226.1 mW m À 2 to 797 mW m À 2 .…”

site). The relationship is demonstrated in depth between the physicochemical properties of the anode surface/interface/bulk (porosity, surface area, hydrophilicity, partical size, charge, roughness, etc.) and the bioelectrochemical performances (electron transfer, electrolyte diffusion, capacitance, toxicity, start-up time, current, power density, voltage, etc.). An outlook for future work is also proposed.
