Carbon Material Optimized Biocathode for Improving Microbial Fuel Cell Performance [PDF]

Frontiers in Microbiology, 2016
To improve the performance of microbial fuel cells (MFCs), the biocathode electrode material of double-chamber was optimized. Alongside the basic carbon fiber brush, three carbon materials namely graphite granules, activated carbon granules (ACG) and activated carbon powder, were added to the cathode-chambers to improve power generation.

Evidence of Spatial Homogeneity in an Electromethanogenic Cathodic Microbial Community

Frontiers in Microbiology, 2019
Microbial electrosynthesis (MES) has been gaining considerable interest as the next step in the evolution of microbial electrochemical technologies. Understanding the niche biocathode environment and microbial community is critical for further developing

Decolourisation of Acid orange 7 in a microbial fuel cell with a laccase-based biocathode: Influence of mitigating pH changes in the cathode chamber [PDF]

, 2017
Biocathodes may be a suitable replacement of platinum in microbial fuel cells (MFCs) if the cost of MFCs is to be reduced. However, the use of enzymes as bio-cathodes is fraught with loss of activity as time progresses.

Electroactivity of phototrophic river biofilms and constitutive cultivable bacteria [PDF]

, 2011
Electroactivity is a property of microorganisms assembled in biofilms that has been highlighted in a variety of environments. This characteristic was assessed for phototrophic river biofilms at the community scale and at the bacterial population scale ...

High-rate biohydrogen production in single-chamber microbial electrolysis cell using iron-sulfide modified biocathode

Environmental science and pollution research international
Microbial electrolysis cells (MEC) can produce hydrogen (H2) at a low energy expense, but the H2 production rate is often limited by poor microbe-electrode interaction.

Accelerated Reduction of Chlorinated Nitroaromatic Antibiotic Chloramphenicol by Biocathode [PDF]

Environmental Science & Technology, 2013
Chlorinated nitroaromatic antibiotic chloramphenicol (CAP) is a priority pollutant in wastewaters. A fed-batch bioelectrochemical system (BES) with biocathode with applied voltage of 0.5 V (served as extracellular electron donor) and glucose as intracellular electron donor was applied to reduce CAP to amine product (AMCl2). The biocathode BES converted

Gold Nanoparticles as Electronic Bridges for Laccase-Based Biocathodes [PDF]

Journal of the American Chemical Society, 2012
Direct electron transfer (DET) reactions between redox enzymes and electrodes can be maximized by oriented immobilization of the enzyme molecules onto an electroactive surface modified with functionalized gold nanoparticles (AuNPs). Here, we present such strategy for obtaining a DET-based laccase (Lc) cathode for O(2) electroreduction at low ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Electrochemical Characterization of Marinobacter atlanticus Strain CP1 Suggests a Role for Trace Minerals in Electrogenic Activity

Frontiers in Energy Research, 2019
The marine heterotroph, Marinobacter atlanticus strain CP1, was recently isolated from the electroautotrophic Biocathode MCL community, named for the three most abundant members: Marinobacter, an uncharacterized member of the Chromatiaceae, and Labrenzia.
