Forming microbial anodes under delayed polarisation modifies the electron transfer network and decreases the polarisation time required. [PDF]
Microbial anodes were formed from compost leachate on carbon cloth electrodes. The biofilms formed at the surface of electrodes kept at open circuit contained microorganisms that switched their metabolism towards electrode respiration in response to a ...

Community Assembly in Wastewater-Fed Pilot-Scale Microbial Electrolysis Cells
The formation of an electrochemically active biofilm is critical to the function of a Microbial Electrolysis Cell (MEC). We used Illumina 16S rDNA sequencing to analyse the formation and composition of anodic biofilms of two pilot-scale MECs, operated in

The microbiology of microbial electrolysis cells
Electromicrobiology is a new discipline that investigates the ability of microbial species to interact with insoluble external electron acceptors and donors. This ability has most commonly been studied through microbial communities found in association with electrodes as part of a microbial electrolysis cell (MEC). MECs are devices that employ bacteria

Analysis of the microbial community of the biocathode of a hydrogen-producing microbial electrolysis cell [PDF]
The microbial electrolysis cell (MEC) is a promising system for hydrogen production. Still, expensive catalysts such as platinum are needed for efficient hydrogen evolution at the cathode. Recently, the possibility to use a biocathode as an alternative for platinum was shown. The microorganisms involved in hydrogen evolution in such systems are not yet

Microbial bioanodes with high salinity tolerance for microbial fuel cells and microbial electrolysis cells [PDF]
Increasing the conductivity of the electrolytes used in microbial electrochemical systems is an essential prerequisite to the large-scale success of these technologies. Microbial bioanodes formed from a salt marsh inoculum under constant acetate feeding generated up to 85 A*m-² in media containing 776 mM NaCl (45 g*L-¹, 1.5 times the salinity of ...

Application of electro-active biofilms [PDF]
The concept of an electro-active biofilm (EAB) has recently emerged from a few studies that discovered that certain bacteria which form biofilms on conductive materials can achieve a direct electrochemical connection with the electrode surface using it ...

Degradation of 2-mercaptobenzothizaole in microbial electrolysis cells: Intermediates, toxicity, and microbial communities [PDF]
The compound 2-mercaptobenzothizaole (MBT) has been frequently detected in wastewater and surface water and is a potential threat to both aquatic organisms and human health (its mutagenic potential has been demonstrated). This study investigated the degradation routes of MBT in the anode of a microbial electrolysis cell (MEC) and the involved microbial

Biofuel cells and their development [PDF]
A biofuel cell electrochemical system based on the oxidation of glucose by glucose oxidase has been developed. The glucose oxidase was immobilised at the electrode surface by a cast Nafion polymer membrane neutralised and modified by tetrabutylammonium ...

Proton transfer in microbial electrolysis cells
Proton transfer in microbial electrochemical cells is as important as electron transfer. This study quantifies proton transfer rates in MEC for the first time. Control of flow rate and loading rate allows improvement in proton transfer rates enabling hydrogen productivities >10 L per L per day.
