Interspecies electron transfer mechanisms between Bacteria and Archaea play a pivotal role during methanogenic degradation of organic matter in natural engineered anaerobic ecosystems. Growing evidence suggests that syntrophic communities does not rely exclusively on the exchange diffusible molecules energy carriers such as hydrogen or formate, rather microorganisms have capability to metabolic electrons more direct manner. Here, we show supplementation micrometer-size magnetite (Fe3O4)...
Abstract Microbial communities are responsible for biological wastewater treatment, but our knowledge of their diversity and function is still poor. Here, we sequence more than 5 million high-quality, full-length 16S rRNA gene sequences from 740 treatment plants (WWTPs) across the world use to construct ‘MiDAS 4’ database. MiDAS 4 an amplicon variant resolved, reference database with a comprehensive taxonomy domain species level all sequences. We independent dataset (269 WWTPs) show that 4,...
Filamentous Chloroflexi species are often present in activated sludge wastewater treatment plants relatively low numbers, although bulking incidences caused by filaments have been observed. A new species-specific gene probe for FISH was designed and using phylum-, subdivision-, morphotype 1851- probes, the abundance of were monitored samples from 126 industrial five European countries. 50% samples, quantities. In most could only be identified with phylum or subdivision indicating presence...
The ability to transfer electrons, via an extracellular path, solid surfaces is typically exploited by microorganisms which use insoluble electron acceptors, such as iron- or manganese-oxides inert electrodes in microbial fuel cells. reverse process, i.e., the of donors respirations, although largely unexplored, could potentially have important environmental applications, particularly for removal oxidized pollutants from contaminated groundwater waste streams. Here we show, first time, that...
In situ bioremediation of industrial chlorinated solvents, such as trichloroethene (TCE), is typically accomplished by providing an organic electron donor to naturally occurring dechlorinating populations. the present study, we show that TCE bacteria can access electrons required for dechlorination directly from a negatively polarized (-450 mV vs. SHE) carbon paper electrode. replicated batch experiments, mixed culture, also containing Dehalococcoides spp., dechlorinated cis-dichloroethene...
The integrated-multistage process proposed herein is a practical example of biorefinery platform in which the organic fraction municipal solid waste (OFMSW) used as valued source for polyhydroxyalkanoates (PHA) and biogas production. Technical economical feasibilities this approach have been demonstrated at pilot-scale, providing possible upgrade to traditional biowaste management practices, presently based on anaerobic digestion (AD). A pH-controlled OFMSW fermentation stage produced liquid...
In the present study a procedure combining cell extraction method and Fluorescence Situ Hybridization (FISH) for molecular monitoring quantification of bacteria in soil aquifer samples is presented. FISH was applied to bacterial cells extracted from matrix by density gradient centrifugation. This separation produced high recovery 76.5%+/-4.4 78.0%+/-3.2, respectively. FISH, performed on harvested cells, permitted perfect visualization bacteria. approach therefore promising situ detection...
Recently, the proof-of-principle of an innovative bioelectrochemical process for trichloroethene (TCE) bioremediation was presented. In this newly developed process, a solid-state electrode polarized to −450 mV (vs SHE), in presence low-potential redox mediator (methyl viologen), is employed as electron donor microbial reductive dechlorination TCE lower or nonchlorinated end products. present study, we investigated influence methyl viologen and concentrations on performance. Using highly...
This study presents the proof-of-concept of "Oil-Spill Snorkel": a novel bioelectrochemical approach to stimulate oxidative biodegradation petroleum hydrocarbons in sediments. The Snorkel" consists single conductive material (the snorkel) positioned suitably create an electrochemical connection between anoxic zone contaminated sediment) and oxic overlying O2-containing water). segment electrode buried within sediment plays role anode, accepting electrons deriving from oxidation contaminants....
