Article Synopsis
- Three strains of electrochemically active bacteria (EAB) were isolated from an anaerobic digester: ADMFC1, ADMFC2, and ADMFC3.
- The genome sequences of these three strains were analyzed and reported, contributing to the scientific knowledge of EAB diversity.
- This research enhances our understanding of the specific roles and environments of EAB within anaerobic digesters.
Article Synopsis
- Researchers are exploring the use of anaerobic-digester sludge and effluent as sources for microbial fuel cells (MFCs) to generate power.
- The study isolated three different strains of electrochemically active bacteria (EAB) from anode biofilms, indicating phylogenetic diversity among the bacteria present in anaerobic digestion.
- These strains show the ability to generate current and contain cytochromes, suggesting they play a key role in electricity production within bioelectrochemical systems.
One of practical challenges in anaerobic-digestion (AD) technology is the cost-effective treatment of residue effluents containing high concentrations of organics, nitrogen and phosphorus (CNP). In order to evaluate the utility of microbial fuel cells (MFCs) for treating anaerobic-digester effluents (ADEs) and generating power from them, laboratory-scale single-chamber MFCs were filled with ADE obtained from a commercial AD plant treating food wastes and thereafter operated by routinely supplying ADE at different hydraulic residence times (HRTs, 5 to 20 days). It is shown that MFCs were able to reduce not only organics in ADE but also nitrogen and phosphorus.
