Although the bio\u2010electrochemical potential of some specific bacterial species such as\n D<\/jats:styled-content>\n ehalcoccoides and\n G<\/jats:styled-content>\n eobacteraceae have been exploited, this ability in other undefined microorganisms has not been extensively assessed. Hence, the focus of this study was to investigate indigenous and potentially bio\u2010electrochemically active microorganisms in\n PCE<\/jats:styled-content>\n \u2010contaminated groundwater. Lab\u2010scale\n MESs<\/jats:styled-content>\n were fed with acetate and carbon electrode\/\n PCE<\/jats:styled-content>\n as electron donors and acceptors, respectively, under biostimulation (\n BS<\/jats:styled-content>\n ) and\n BS<\/jats:styled-content>\n \u2010bioaugmentation (\n BS\u2010BA<\/jats:styled-content>\n ) regimes. Molecular analysis of the indigenous groundwater community identified mainly\n \n S<\/jats:styled-content>\n pirochaetes\n <\/jats:italic>\n ,\n \n F<\/jats:styled-content>\n irmicutes\n <\/jats:italic>\n ,\n \n B<\/jats:styled-content>\n acteroidetes\n <\/jats:italic>\n , and \u03b3 and \u03b4\n \n \u2010\n P<\/jats:styled-content>\n roteobacteria\n <\/jats:italic>\n . Environmental scanning electron photomicrographs of the anode surfaces showed extensive indigenous microbial colonization under both regimes. This colonization and\n BS<\/jats:styled-content>\n resulted in 100% dechlorination in both treatments with complete dechlorination occurring 4 weeks earlier in\n BS\u2010BA<\/jats:styled-content>\n samples and up to 11.5\u2009\u03bc\n A<\/jats:styled-content>\n of current being generated. The indigenous non\u2010\n \n D<\/jats:styled-content>\n ehalococcoides\n <\/jats:italic>\n community was found to contribute significantly to electron transfer with \u223c61% of the current generated due to their activities. This study therefore shows the potential of the indigenous non\u2010\n \n D<\/jats:styled-content>\n ehalococcoides\n <\/jats:italic>\n bacterial community in bio\u2010electrochemically reducing\n PCE<\/jats:styled-content>\n that could prove to be a cost\u2010effective and sustainable bioremediation practice.\n <\/jats:p>","DOI":"10.1111\/1751-7915.12089","type":"journal-article","created":{"date-parts":[[2013,10,11]],"date-time":"2013-10-11T21:35:02Z","timestamp":1381527302000},"page":"54-63","source":"Crossref","is-referenced-by-count":21,"title":["Sustainable remediation: electrochemically assisted microbial dechlorination of tetrachloroethene\u2010contaminated groundwater"],"prefix":"10.1111","volume":"7","author":[{"given":"Sayali S.","family":"Patil","sequence":"first","affiliation":[{"name":"School of Biological Sciences Flinders University of South Australia Adelaide SA 5042 Australia"},{"name":"Department of Applied Biosciences Royal Melbourne Institute of Technology Bundoora Vic. 3083 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric M.","family":"Adetutu","sequence":"additional","affiliation":[{"name":"Department of Applied Biosciences Royal Melbourne Institute of Technology Bundoora Vic. 3083 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacqueline","family":"Rochow","sequence":"additional","affiliation":[{"name":"School of Biological Sciences Flinders University of South Australia Adelaide SA 5042 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James G.","family":"Mitchell","sequence":"additional","affiliation":[{"name":"School of Biological Sciences Flinders University of South Australia Adelaide SA 5042 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew S.","family":"Ball","sequence":"additional","affiliation":[{"name":"Department of Applied Biosciences Royal Melbourne Institute of Technology Bundoora Vic. 3083 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,10]]},"reference":[{"key":"e_1_2_6_2_1","unstructured":"ATSDR(2007)Substances most frequently found in completed exposure pathways (CEPs) at hazardous waste Sites.
