A precious metal catalyst without heating is not suitable to oxidize tritium under conditions of low hydrogen concentration and room temperature. In addition, under a moisture condition, tritium oxidation of a precious metal catalyst drops drastically since moisture adsorbs active sites on the surface of the catalyst. Hence, as a method of tritium oxidation under a moisture condition at room temperature, we have focused on bacterial oxidation of tritium by hydrogen-oxidizing bacteria in natural soil to realize a passive reactor. In this study, we investigated the effect of hydrogen concentration on tritium oxidation by hydrogen-oxidizing bacteria in natural soils to understand the characteristic of tritium oxidation by hydrogen-oxidizing bacteria from the viewpoint of\nengineering. In our experiment, efficiency of tritium oxidation by a natural soil was obtained at room temperature in the range of hydrogen concentration from 0.5 to 10000 parts per million (ppm) under a moisture condition. The efficiency of tritium oxidation was the highest at a hydrogen concentration of 0.5 ppm, which equals the value of the hydrogen concentration in air. Our results show that hydrogen-oxidizing bacteria could efficiently oxidize tritium with a low concentration of hydrogen, at room temperature, with high moisture. This showed a tendency opposite to a metal catalyst. A bioreactor using hydrogen-oxidizing bacteria complemented a conventional catalytic reactor using a precious metal catalyst since hydrogen-oxidizing bacteria could oxidize tritium efficiently with a low concentration of hydrogen, at room temperature, with high moisture.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1080/15361055.2019.1704572","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/15361055.2019.1704572","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1536-1055","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Edao, Yuuki"}],"nameIdentifiers":[{"nameIdentifier":"999530","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwai, Yasunori"}],"nameIdentifiers":[{"nameIdentifier":"999531","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yuuki, Edao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999532","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasunori, Iwai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999533","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Investigation on Characteristic of Tritium Oxidation by Natural Soils","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Investigation on Characteristic of Tritium Oxidation by Natural Soils"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-02-26"},"publish_date":"2020-02-26","publish_status":"0","recid":"79061","relation_version_is_last":true,"title":["Investigation on Characteristic of Tritium Oxidation by Natural Soils"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:44:42.347710+00:00"}
