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....
Bioelectrochemical systems (BES) can provide an energy efficient way to recover nutrients from wastewaters. However, the electron donors available in wastewater are often not sufficient total amount of nutrients. This work investigates hydrogen (H2) as additional substrate for bioanodes. be produced fermentation complex organic waste or could recycled cathode. Understanding how influence competition electroactive microorganisms (EAM) with methanogens H2 gas different sources is key...
Bio-electrochemical systems (BESs) can recover ammonium at low specific energy inputs and produce hydrogen gas. A reason hampering development of large-scale applications for recovery is the general instability bio-generated current thereby variable TAN (ammonia ammonium) effluent concentrations. Electrochemical recovery, such as recycling electrochemical system (HRES), fine-tune applied current, but require higher than BES, may an additional external supply in case HRES. This research...
Bio-electrochemical ammonium recovery (BEAR) can close the cycle between anthropogenic emission of reactive nitrogen and energy intensive fixation in Haber-Bosch process. BEAR is currently limited by bio-electrogenic degradability treated wastewater. Here, we investigated blackwater, hydrolyzed human urine, cow manure pig as prospective wastewaters for a standardized experimental design. We found that bio-electrochemical conversion efficiencies ranged from 63% (blackwater) to 42% (cow...
