1 Active biocatalyst such as microorganisms or enzymes liberate electron while electron donors are 2 consumed in biological fuel cells. Biological fuel cells are a novel technology which produces bio-3 electrochemical power using various materials such as complex organic waste or natural organic 4 matter in the anaerobic anode condition. Recently, great attentions have been paid to biological 5 fuel cells due to their mild operating conditions and using variety of biodegradable substrates as 6 fuel. Sediment Microbial Fuel cell (SMFC) is a kind of Microbial Fuel Cell (MFC) that can 7 produce electrical current by sediment's organic matter content and using bacterial metabolism. 8 SMFCs have been developed in the past decade to provide a renewable power source and organic 9 matter removal. SMFC differs from other MFCs due to the essentially complete anoxic condition 10 on the anode and membrane less structure. To further improve SMFC technology, this paper 11 focuses on SMFC's limitation and challenges and collects latest surveys in this field.12

Microbial fuel cells (MFCs) provide a new opportunity to produce sustainable energy from the treatment of the organic matter in wastewater. However, the power density of MFCs for large‐scale application is limited by the performance of anode, with one of the major factors being low bacterial adhesion capacity. In this work, a novel macroporous sugarcane carbon (SC) is prepared by a direct carbonization process, and is used as anode material in a packed MFC. A maximum power density of 59.94±2.81 W m−3 is achieved in an MFC equipped with the SC anode, which is 2.62 times higher than that of the granular activated carbon (GAC) anode. A microbial analysis shows that the SC anode has a higher amount of biomass and the abundance of Geobacter is 6.6 times higher than that of the GAC anode, which indicates that the SC anode has higher biocompatibility. Further studies show that the macroporous structure, high surface roughness, large surface hydrophobicity and low absolute value of zeta potential favor bacterial adhesion to the SC anode surface. Therefore, this study provides an excellent anode material for high‐performance MFCs, and reveals the impact of physicochemical properties on power generation.

“…Consequently, a lower voltage and power output is obtained from a SMFC. Several attempts have been made to improve SMFC performance namely optimizing the external resistance (Song et al 2010), improving the sediment conductivity (Babu and Mohan 2012), amendment of colloidal iron oxyhydroxide (Zhou et al 2014), modifying the electrode materials (Fu et al 2014), and changing the electrode configuration and assembly (Martins et al 2014;An et al 2013). In addition, the supply of organic matter, such as glucose, plant rhizodeposits (De Schamphelaire et al 2010) or biomass likes chitin or cellulose (He et al 2007;Rezaei et al 2008), has also been shown to increase power production.…”

Phosphorus–iron interaction in sediments: can an electrode minimize phosphorus release from sediments?

All restoration strategies to mitigate eutrophication depend on the success of phosphorus (P) removal from the water body. Therefore, the inputs from the watershed and from the enriched sediments, that were the sink of most P that has been discharged in the water body, should be controlled. In sediments, iron (hydr)oxides minerals are potent repositories of P and the release of P into the water column may occur upon dissolution of the iron (hydr)oxides mediated by iron reducing bacteria. Several species of these bacteria are also known as electroactive microorganisms and have been recently identified in lake sediments. This capacity of bacteria to transfer electrons to electrodes, producing electricity from the oxidation of organic matter, might play a role on P release in sediments. In the present work it is discussed the relationship between phosphorus and iron cycling as well as the application of an electrode to work as external electron acceptor in sediments, in order to prevent metal bound P dissolution under anoxic conditions.
