A sediment microbial fuel cell (SMFC) is a system in which MFC applied to layer of an aqueous for water purification. SMFCs can remove contaminants from sediments and decompose organic matter while simultaneously producing electrical energy. SMFC installed the form installing anode at bottom cathode above sediment, connecting two electrodes through external circuit. Early were developed be used...

In aquatic environment, microorganisms such as bacteria and microalgae usually secrete a matrix of mucilaginous extracellular polymeric substances (EPS) to form a “microbial biofilm” when they are associated with solid surfaces (e.g., sediment particles, plant surfaces). Biofilms and the associated mucilaginous secretions form a cohesive matrix surrounding sediment particles, modifying the sedi...

A sediment microbial fuel cell (MFC) produces electricity through the bacterial oxidation of organic matter contained in the sediment. The power density is limited, however, due in part to the low organic matter content of most marine sediments. To increase power generation from these devices, particulate substrates were added to the anode compartment. Three materials were tested: two commercia...

Microbial solar cells (MSCs) are microbial fuel cells (MFCs) that generate their own oxidant and/or fuel through photosynthetic reactions. Here, we present electrochemical analyses and biofilm 16S rRNA gene profiling of biocathodes of sediment/seawater-based MSCs inoculated from the biocathode of a previously described sediment/seawater-based MSC. Electrochemical analyses indicate that for thes...

A floating microbial fuel cell (FMFC) has been designed and its performance has been evaluated for 153 days. The power output gradually increased to a maximum value of 390 mW/m(3) at 125 days. The polarization resistance of the anode (R(p)(a)) changed with operating time reaching a minimum value at 125 days, while the polarization resistance of the cathode (R(p)(c)) was relatively constant and ...

The use of packed bed microbial fuel cell (MFC) for septic waste water remediation and electricity generation was carried out for 18 days retention period. In the study, the multistage microbial fuel cells were designed. Septic wastewater qualities such as Biochemical Oxygen Demand (BOD), nitrate, TSS, and pH of both the raw and treated wastewater were determined in the laboratory on three days...

Miniature microbial fuel cells have recently drawn lots of attention as portable power generation devices due to their short startup time and environmentally-friendly process which could be used for powering small integrated biosensors. We designed and fabricated a microbial fuel cell in a microfluidic platform. The device was made in polydimethylsiloxane with a volume of 4 μL and consisted of ...

Laccase and bilirubin oxidase were successfully displayed on the surface of yeast cells. Subsequently, these modified yeast cells were used in the cathode compartment of a microbial fuel cell. The performance of the fuel cells is compared.

Microbial fuel cell is a bio-electrochemical system that drives a current by using bacteria and mimicking bacterial interactions found in nature. The electricigens and its activity have important influence on the power generation capacity and organic matter degradation ability of MFC system. The common types of electricigens and their application situation in microbial fuel cell are summarized ...
