“…The observed steady increase in power production over time was consistent with previous reports showing that MFC power production correlates with the thickness of the anode-colonizing biofilm (Nevin et al, 2008). No evidence of longer-term operation leading to a state of biofilm "exhaustion" in which the performance of the electrogenic community declines (Kassongo et al, 2011) were found for this particular settings.…”

In this paper we describe applications of our ASAR package to functional, taxonomic and pathways analysis of metagenomes and propose future plans and perspectives. To illustrate an analytical potential of ASAR, we discuss outcomes of several projects. The main focus is made on metabolic plasticity of electrochemically active microbial communities and a potential role of integrated symbiotic bacterial interactions; antipathogenic properties of BES, manifested in its capacity to remove some pathogens from waste streams; and medical applications of this technology. We present ASAR-based metagenome analysis of evolving bacterial community from distillery waste over period of 36 months in BES environment as an example. Application of ASAR to personalised analyses of gut microbiome (GM) and the data interpretation based on publically available association studies are also discussed in this publication.

“…The purpose of acclimatization is to increase electrode performance by enhancing biofilm attachment and/or allowing the biofilm electrode to reach a steady-state OCP prior to use in a BES (Larrosa-Guerrero et al 2010; Cheng et al 2011; Kassongo and Togo 2011; Renslow et al 2011a). The method of acclimatization affects the type of EAB grown on the biofilm electrode and can be focused on control of the current or of the biofilm electrode potential.…”

Electrochemically active biofilms: facts and fiction. A review

This review examines the electrochemical techniques used to study extracellular electron transfer in the electrochemically active biofilms that are used in microbial fuel cells and other bioelectrochemical systems. Electrochemically active biofilms are defined as biofilms that exchange electrons with conductive surfaces: electrodes. Following the electrochemical conventions, and recognizing that electrodes can be considered reactants in these bioelectrochemical processes, biofilms that deliver electrons to the biofilm electrode are called anodic, ie electrode-reducing, biofilms, while biofilms that accept electrons from the biofilm electrode are called cathodic, ie electrode-oxidizing, biofilms. How to grow these electrochemically active biofilms in bioelec-trochemical systems is discussed and also the critical choices made in the experimental setup that affect the experimental results. The reactor configurations used in bioelectrochemical systems research are also described and the authors demonstrate how to use selected voltammetric techniques to study extracellular electron transfer in bioelectrochemical systems. Finally, some critical concerns with the proposed electron transfer mechanisms in bioelectrochemical systems are addressed together with the prospects of bioelectrochemical systems as energy-converting and energy-harvesting devices.

“…Hence, anodes were enriched with microorganisms inherent to whey from 1 to 3 months before MFC activity. The result significantly enhanced and offered CE of 80.9%, COD removal of 92.8%, and Pdm of 1800mW m -2 [86]. Two biological methods, MFC to traditional technology (fermentation by Lactobacillus bulgaricus) have been compared for treating whey and condensed whey.…”

Today, the world is facing climate change challenges with environmental protection being a top priority. Optimizing energy consumption due to its high cost and environment protection is a basic human demand. For industries, reduction in production costs is determinative to success. In this regard, Microbial fuel cell (MFC) is a unique promising technology with wastewater treatment and bioelectricity generation. The MFCs will help reduce energy consumption, curb the wastewater pollution, and standardize it for releasing into the environment. The food industry by producing high volumes of biomass with high organic pollution load are highly prone to use in MFCs as a substrate. Various food industry effluents have been tested, in real or synthetic form in the MFCs. Due to the improvements in the process and progress in novel configurations, better results have been increasingly obtained. Now, the MFC can be used in the industries individually or by integration with other technologies. In this review, the latest results from the use of food industry wastewater in MFCs along with effective process conditions are evaluated.
