A cross-laboratory study on microbial fuel cells (MFC) which involved different institutions around the world is presented. The aims to assess development of autochthone pools enriched from domestic wastewater, cultivated in identical single-chamber MFCs, operated same way, thereby approaching idea developing common standards for MFCs. MFCs are inoculated with wastewater geographic locations. acclimation stage and, consequently, startup time longer or shorter depending inoculum, but all...
The aim of the study was to provide experimental proof-of-concept that stand-alone power generation based on microbial fuel cells (MFCs) operated using human feces as substrate can be achieved. A pit latrine is typically employed for decentralized treatment e.g. in regions without access centralized wastewater infrastructures installed sampling site. It philosophy components, i.e. anodes and cathodes, used MFCs had low-cost precursors. This achieved by recycling common household materials or...
Abstract This study focuses on improving the treatment capacity and current output of electrochemically active microorganisms (EAM) during real wastewater treatment. A multi‐carbon‐source artificial consisting several carbon sources, which represent typical fermentation hydrolysis products derived from otherwise myriad constituents, was developed as a more realistic simulation thereof. An preselected inoculum obtained by means re‐suspension well‐established EAM biofilm, subsequently used to...
Abstract In this study, electrochemically active microbial biofilms were cultivated and studied at continuously alternating electrode potentials. Compared to cultivation operation a single constant potential, method enhanced turnover maximum current densities. Electrochemically in multi‐carbon source culture for several biofilm generations subsequently fed with real, domestic wastewater. potential cultivation, average ( N =12) limiting density +0.2 V vs. Ag/AgCl increased from 0.350±0.101...
A new concept of aerobic microbial electrochemical technology allowed combining the merits both aerobes and exoelectrogens at same solid–liquid interface for efficient synergistic pollutants removal from wastewater.
Abstract This study investigated, if a mixed electroactive bacterial (EAB) culture cultivated heterotrophically at positive applied potential could be adapted from oxidative to reductive or bidirectional extracellular electron transfer (EET). To this end, periodic reversal regime between − 0.5 and 0.2 V vs. Ag/AgCl was applied. yielded biofilm detachment mediated electroautotrophic EET in combination with carbonate, i.e., dissolved CO 2 , as the sole carbon source, whereby emerged (S1)...
Abstract Whey is a main by‐product of the dairy industry and difficult to valorise for small medium enterprises. Microbial electrochemical technologies could be key these enterprises exploit this current waste product. removal conversion electrical was investigated at microbial anodes using potentiostatically controlled half‐cell experiments. The were fed with whey solution containing ca. 1 g L −1 COD. This can reliably cleaned average efficiencies 65.8±10.9 %. coincided maximum densities...
Abstract This study details, in‐depth, the development of graphite paper as electrodes, specifically anodes, for microbial electrochemical technologies. Processed natural powders were used an active filler substance in composites. Mechanical and electrical properties balanced during development. Graphite papers with 80 wt% content had tear lengths 730±58 m resistivities 0.014±0.001 Ω cm. Electrochemically biofilms on these materials, cultivated from biomass taken bioanodes already running...

The aim of the project was to provide full experimental proof-of-concept that stand-alone power generation based on microbial fuel cells (MFCs) operated human feces from pit latrines as substrate can be achieved. Thereby, establishment these eLatrines MFC-technology and components were gained low-cost materials through low-tech approaches. For latter system developed so utilize many possible produced by non-trained persons in decentralized areas for example developing countries, e.g....
