Characterization of an electro-active biocathode capable of dechlorinating trichloroethene and cis-dichloroethene to ethene

Bioelectrochemical systems for simultaneously production of methane and acetate from carbon dioxide at relatively high rate

“…Bioelectrochemical systems with microbial biocathodes may offer lower-cost cathode catalysts and get more opportunities for commercial applications [3,4]. Recently, microbial biocathodes have been explored to be used in other fields, including the biological recovery of heavy metal [5,6], reduction of nitrate [7e9] and chlorinated [10,11]. The use of CO 2 by means of fixation and transformation for producing chemicals, which can simultaneously reduce CO 2 emissions and generate added value [12].…”

Sulfate reduction with electrons directly derived from electrodes in bioelectrochemical systems

“…In the device, microorganisms were used as biocatalysts to accept electrons from the cathode [2] for the reduction of oxidized contaminants including nitrate [3], U (VI) [4] and chlorinated organic compounds [5][6][7]. The proposed mechanisms include: (i) direct electron transfer via redox components located on the outer surface of the microorganism (e.g.…”

Bioelectrochemical Treatment of Contaminated Groundwater

“…cathode), is used as an electron donor for the microbial reductive dechlorination of TCE to harmless ethane. Not only TCE could be removed using BES, carbon-based electrode polarized at -0.55 V vs. SHE can serve as direct electron donor for the microbial reductive dechlorination of chloroethenes (TCE and cis-DCE) to harmless non-chlorinated end-products [16].…”
