In this context, we have constructed planted (Iris sibirica) biofilters to assess the impact of different electrically conductive bed materials (electroconductive coke, electroconductive biochar, non-electroconductive biochar and gravel) by analyzing the (i) wastewater treatment efficiency (COD and nitrogen removal), (ii) bioelectrochemical response, and (iii) diversity of microbial communities. Electrically conductive materials outperformed non-conductive ones allowing removal rates as high as 175-180 gCOD/bed*m3 day capable to support footprint as low 0.4 m2/pe. In contrast, the highest nitrogen removal rates were achieved with non-conductive biochar in presence of plants (80 %) regardless the anoxic conditions of the assay. This was confirmed by the presence of annamox bacteria like Planctomycetes. Furthermore, the presence of a marked electric potential profile along the bed height in electroconductive materials together with redox pairs (cyclic voltammetry analysis) demonstrated an effective electron flow from bottom to uppermost layers of the bed (geoconductor mechanism). In electroconductive biochar, such effective conductivity-based model co-exists with a geobattery mechanism due to presence of electroactive phenolic and carbonyl/quinone groups and/or microporosity. Microbial biodiversity analysis revealed the impact of plants just at the upper layers of the biofilters where roots and Rhizobium predominate. Bacteria from genus Clostridium were dominant in gravel inert material; in contrast, bacteria from genus Geobacter (12%) and Trichococcus (30%) outcompete the rest of communities for an effective colonization of carbonaceous beds, suggesting their main role as part of the electrosyntrophies mechanism after METland\u00ae.", "keywords": ["Electroactive bacteria", "0301 basic medicine", "0303 health sciences", "Metland\u00ae", "Electroconductive biochar", "Wastewater treatment", "QD Chemistry", "6.

This study aims at unveiling the potential biologic pathways for the bioelectrochemical oxidation of ammonium to dinitrogen gas in an anaerobic bioelectrochemical system (BES). Known intermediate metabolites of this process (hydroxylamine, nitrite and nitrate) were monitored in two BES replicates. Ammonium was fully oxidized to dinitrogen gas without intermediates accumulation in the anodic chamber. Achromobacter sp. was the most abundant microorganism (up to 60%, according to sequence reads) in the mixed community. Hydroxylamine and nitrite oxidation were electroactive processes, reinforcing the role of the anodic electrode as the electron acceptor for ammonium oxidation. Taking it all together, ammonium can be removed in BES by a combination of different bio/electrochemical processes.

Sustainable and resilient technologies are required for their treatment. The present study aims to evaluate microbial electrochemical technologies (METs) for treating groundwater contaminated with nitrate (NO3-) while containing arsenic (in form of arsenite (As(III)) as a co-contaminant. The treatment was based on the combination of nitrate reduction to dinitrogen gas and arsenite oxidation to arsenate (exhibiting less toxicity, solubility, and mobility), which can be removed more easily in further post-treatment. We operated a bioelectrochemical reactor at continuous-flow mode with synthetic contaminated groundwater (33 mg N-NO3- L-1 and 5 mg As(III) L-1) identifying the key operational conditions. Different hydraulic retention times (HRT) were evaluated, reaching a maximum nitrate reduction rate of 519 g N-NO3- m3Net Cathodic Compartment d-1 at HRT of 2.3 h with a cathodic coulombic efficiency of around 100 %. Simultaneously, arsenic oxidation was complete at all HRT tested down to 1.6 h reaching an oxidation rate of up to 90 g As(III) m-3Net Reactor Volume d -1. Electrochemical and microbiological characterization of single granules suggested that arsenite at 5 mg L-1 did not have an inhibitory effect on a denitrifying biocathode mainly represented by Sideroxydans sp.
