Respiration of elemental sulfur is closely linked to iron respiration and may represent one of the first respiratory processes to evolve on early earth.  The gene deletion system described in this paper alleviates many problems associated with previous genetic methods in \u003Cem\u003EShewanella\u003C\/em\u003E and allows for greater efficiency in constructing and testing mutant strains.  \u003Cem\u003ES. oneidensis\u003C\/em\u003E MR-1 is an attractive model organism for studying anaerobic respiratory processes, including those required for bioremediation of contaminant radionuclides at U.S. Department of Energy sites.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"School of Biology graduate student Justin Burns was named a winner of the 2009 SAIC Georgia Tech Student Paper Competition, for his paper \u0022Anaerobic respiration of elemental sulfur and thiosulfate by \u003Cem\u003EShewanella oneidensis\u003C\/em\u003E MR-1 requires \u003Cem\u003EpsrA\u003C\/em\u003E, a homolog of the \u003Cem\u003EphsA\u003C\/em\u003E gene of \u003Cem\u003ESalmonella enterica\u003C\/em\u003E serovar Typhimurium LT2\u0022.","format":"limited_html"}],"field_summary_sentence":[{"value":"Biology Grad Student Wins Student Paper Competition"}],"uid":"27245","created_gmt":"2010-03-15 00:00:00","changed_gmt":"2016-10-08 03:11:13","author":"Troy Hilley","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2010-03-15T00:00:00-04:00","iso_date":"2010-03-15T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"101671":{"id":"101671","type":"image","title":"Buzz","body":null,"created":"1449178166","gmt_created":"2015-12-03 21:29:26","changed":"1475894720","gmt_changed":"2016-10-08 02:45:20"}},"media_ids":["101671"],"related_links":[{"url":"http:\/\/www.biology.gatech.edu\/","title":"School of Biology"},{"url":"http:\/\/www.biology.gatech.edu\/faculty\/tom-dichristina\/","title":"Thomas DiChristina"}],"groups":[{"id":"1275","name":"School of Biological Sciences"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003ESchool of Biology\u003C\/strong\u003E\u003Cbr \/\u003EBiology\u003Cbr \/\u003E\u003Ca href=\u0022mailto:admin@biology.gatech.edu\u0022\u003EContact School of Biology\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-3700\u003C\/strong\u003E","format":"limited_html"}],"email":["admin@biology.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
