Microbial fuel cells containingProteus vulgaris and oxidation-reduction (“redox”) mediators were investigated. The bacteria were chemically immobilized onto the surface of graphite felt electrodes, which supported production of continuous electric current and could be reused after storage A computer-controlled carbohydrate feed system enabled the cell to generate a constant output with improved efficiency compared to the performance obtained with single large additions of fuel. The response to… Expand
Microbial Fuel Cells
Cellular life exists at the interface between electrochemical extremes. The energy of most living cells depends on the transfer of electrons from intracellular, electrically reduced biochemicals toExpand
Kinetics of Anode Reactions for a Yeast‐Catalysed Microbial Fuel Cell
Chronoamperometric investigations with rotating disc electrodes (RDEs) were used to characterise the anodic half-cell of yeast powered microbial fuel cells using methylene blue (MB) as a mediator.Expand
A tubular microbial fuel cell
Cell potential and power performance for tubular microbial fuel cells utilising manure as fuel are reported. The microbial fuel cells do not use a mediator, catalysts or a proton exchange membrane.Expand
Electrically conductive, immobilized bioanodes for microbial fuel cells.
The power densities of microbial fuel cells with yeast cells as the anode catalyst were significantly increased by immobilizing the yeast in electrically Conductive alginate electrodes, suggesting that proton transport limitations and not electrical conductivity will limit the power density from electrically conductive immobilized anodes.

Effect of initial carbon sources on the performance of microbial fuel cells containing Proteus vulgaris.
This work demonstrates that optimum utilization of carbon sources by microorganisms, which leads to the maximization of fuel cell performance, is possible simply by adjusting initial carbon sources. Expand
Use of Carbon Nanoparticles for Bacteria Immobilization in Microbial Fuel Cells for High Power Output
Low power density, a main drawback in a mediator-type microbial fuel cell (MFC), has been greatly increased by immobilizing bacteria using carbon nanoparticles. Proteus vulgaris-containing carbonExpand
Construction and operation of a novel mediator- and membrane-less microbial fuel cell
Abstract A membrane-less microbial fuel cell (ML-MFC) with the internal resistance of 3.9 MΩ was used to enrich a microbial consortium oxidizing electron donors with concomitant current generation.Expand
Improvement of cathode reaction of a mediatorless microbial fuel cell
Oxygen diffuses through the cation-specific membrane, reducing the coulomb yield of the fuel cell. In the present study, attempts were made to enhance current generation from the fuel cell byExpand
Electrocatalysis in microbial fuel cells—from electrode material to direct electrochemistry
Microbial fuel cells (MFCs) are promising clean energy sources for simultaneous recycling of organic waste while harvesting electricity. The electrocatalysis of the anode is crucial for improvementExpand
Improved microbial electrocatalysis with neutral red immobilized electrode
Abstract Efficient electron transfer (ET) between microbes and electrodes is a key factor for electricity generation in microbial fuel cell (MFC). The utilization of reversible redoxExpand


Glucose Metabolism in a Microbial Fuel Cell. Stoichiometry of Product Formation in a Thionine-mediated Proteus vulgaris Fuel Cell and its Relation to Coulombic Yields
The pattern of glucose metabolism was studied in a thionine-mediated Proteus vulgaris fuel cell by using 14C-labelled glucose, finding that under anaerobic conditions acetate, lactate and ‘propionate’ were produced and not reutilized. Expand
Protein measurement with the Folin phenol reagent.
Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein. Expand
