Using carbon dioxide for bioproduction combines decreased greenhouse gas emissions with a dependence on fossil production of multicarbon products. Microbial electrosynthesis (MES) enables this, using renewable energy to drive the reduction CO2 at cathode an electrochemical cell. To date, low product concentrations preclude cost-effective extraction during MES. Here we present approach that couples and recovery acetate in single, three-chamber reactor system. Acetate was produced 61%...
Abstract Biochars have gathered considerable interest for agronomic and engineering applications. In addition to their high sorption ability, biochars been shown accept or donate amounts of electrons to/from environment via abiotic microbial processes. Here, we measured the electron accepting (EAC) donating (EDC) capacities wood-based pyrolyzed at three different highest treatment temperatures (HTTs: 400, 500, 600 °C) hydrodynamic electrochemical techniques using a rotating disc electrode....
Stainless steel (SS) can be an attractive material to create large electrodes for microbial bioelectrochemical systems (BESs), due its low cost and high conductivity. However, poor biocompatibility limits successful application today. Here we report a simple effective method make SS biocompatible by means of flame oxidation. Physicochemical characterization electrode surface indicated that iron oxide nanoparticles (IONPs) were generated in situ on felt IONPs-coating dramatically enhanced the...
Microbial electrochemistry has from the onset been recognized for its sensing potential due to microbial ability enhance signals through metabolic cascades, relative selectivity toward substrates, and higher stability conferred by self-replicate. The greatest challenge achieve stable efficient transduction between a microorganism an electrode surface. Over past decades, new kind of architecture observed spontaneously develop on polarized electrodes: electroactive biofilm (EAB). EAB conducts...
Seasonal or permanent water scarcity in off-grid communities can be alleviated by recycling decentralized wastewater treatment systems. Nature-based solutions, such as constructed wetlands (CWs), have become popular solutions for sanitation remote locations. Although typical CWs efficiently remove solids and organics to meet reuse standards, polishing remains necessary other parameters, pathogens, nutrients, recalcitrant pollutants. Different CW designs coupled with electrochemical...
The involvement of Shewanella spp. in biocorrosion is often attributed to their Fe(III)-reducing properties, but they could also affect corrosion by using metallic iron as an electron donor. Previously, we isolated strain 4t3-1-2LB from acetogenic community enriched with Fe(0) the sole Here, investigated its use donor fumarate acceptor and explored corrosion-enhancing mechanism. Without Fe(0), fermented succinate CO2, was shown reaction stoichiometry pH. With completely reduced increased...
Abstract The mechanism of electron transport across electroactive biofilms (EABs) is high interest and still a matter debate. Quantitative assessments their redox conduction take considerable time require non‐turnover conditions (absence substrate), which can be detrimental to EABs. Here, we measure the charge‐transport parameters Geobacter spp. dominated EABs with double potential step chronoamperometry (DPSC) Cottrell analysis. DPSC measurement simpler much faster than usual techniques...
Sporomusa sphaeroides related strains are to date the only homoacetogens known increase metallic iron corrosion. The goal of this work was isolate additional homoacetogenic bacteria capable using Fe(0) as electron donor and explore their extracellular transfer mechanism. Enrichments were started from anoxic corrosion products yielded Acetobacterium main genus. Isolations performed with a new procedure plates powder top layer. An strain, closely A. malicum wieringae, isolated, in addition S....
We demonstrate that a more efficient redox hydrogel structure can be achieved by engineering the size and surface charge of bioelectrocatalyst. Deglycosylated glucose oxidase (GOx) modified electrode exhibits higher current density than native GOx, for same molar composition hydrogel. This improvement is very likely due to rather better intrinsic electron transfer between FAD/FADH2 center mediator.
Nitrate contamination is a common problem in groundwater around the world. can be cathodically reduced bioelectrochemical systems using autotrophic denitrifiers with low energy investment and without chemical addition. Successful denitrification was demonstrated previous studies both microbial fuel cells electrolysis (MECs) continuous current flow, whereas impact of intermittent supply (e.g., fluidized-bed system) on particularly electron-storing capacity denitrifying electroactive biofilms...
