Coupled Adsorption and Biodegradation of Trichloroethylene on Biochar from Pine Wood Wastes: A Combined Approach for a Sustainable Bioremediation Strategy

Microorganisms, 2022
Towards chlorinated solvents, the effectiveness of the remediation strategy can be improved by combining a biological approach (e.g., anaerobic reductive dechlorination) with chemical/physical treatments (e.g., adsorption).

Presence, Diversity, and Enrichment of Respiratory Reductive Dehalogenase and Non-respiratory Hydrolytic and Oxidative Dehalogenase Genes in Terrestrial Environments

Frontiers in Microbiology, 2019
Organohalide-respiring bacteria have been linked to the cycling and possible respiration of chlorinated natural organic matter (Cl-NOM) in uncontaminated soils and sediments. The importance of non-respiratory hydrolytic/oxidative dechlorination processes

Role of Graphene Oxide in the Nucleation and Growth of Gold Nanoparticles Revealed by Operando Time‐Resolved Studies

Angewandte Chemie, EarlyView.
Graphene oxide accelerates AuCl4− reduction under irradiation and directs edge‐selective nucleation and quasi‐one‐dimensional organization of gold nanoparticles at oxygen‐rich boundaries. Operando SAXS and UV–vis spectroscopy, supported by pulse radiolysis and DFT, reveal how progressive conversion of GO to rGO removes interfacial constraints, shifting

Study on the Effect of Electrochemical Dechlorination Reduction of Hexachlorobenzene Using Different Cathodes

Journal of Analytical Methods in Chemistry, 2014
Hexachlorobenzene (HCB) is a persistent organic pollutant and poses great threat on ecosystem and human health. In order to investigate the degradation law of HCB, a RuO2/Ti material was used as the anode, meanwhile, zinc, stainless steel, graphite, and ...

Validation of an integrative methodology to assess and monitor reductive dechlorination of chlorinated ethenes in contaminated aquifers

Frontiers in Environmental Science, 2016
Bioremediation of tetra-and trichloroethene-contaminated aquifers is frequently hampered due to incomplete dechlorination to the more toxic dichloroethene (DCE) and vinyl chloride (VC), indicating insufficient knowledge about the biological mechanisms ...

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

, 2011
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

Advanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Determination of electron donors in the reductive dechlorination of tetrachloroethene [PDF]

, 1998
Several substrates, namely fatty acids and alcohols, were used to enhance the reductive microbial dechlorination of PCE to ethene. All of the microcosms amended with the volatile fatty acids (butyrate, succinate, lactate, formate, butyrate/formate ...
