In lower Cu（II）−H2O2−DMPO system （1 mM Cu）, DMPO-OH derived from hydroxyl\nradical-trapping was mainly observed. However, in higher Cu（II）−H2O2−DMPO system （4 mM Cu）, most of DMPO-OH was derived from the nucleophillic addition of water molecule. Neutron irradiation of Cu（II） ion did not affect the DMPO-OH formation. Stable Cu（II） complex of phthalocyanin, which could produce 64Cu recoil atoms by neutron irradiation, did not generated DMPO-OH in Cu（II）−H2O2−DMPO system. Thus, the effects of microbial cells on hydroxyl radical generation were examined in lower Cu（II）−H2O2−DMPO system. ESR signal intensity of DMPO-OH in the system was heavily decreased by the addition of microbial cells. Its decrease effects were far larger than that in UV irradiated−H2O2−DMPO system. The microbial cells having higher ability to sorb copper showed relatively smaller ID50 values indicating the microbial amounts which decreased the signal intensities of DMPO-OH to half of\nthose in non-microbial. These results suggested that the generation of hydroxyl radical would be concerned with the strength of coupling between Cu（II） ion and microbial cells.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本医学館","subitem_publisher_language":"ja"},{"subitem_publisher":"Magnetic resonance in medicine","subitem_publisher_language":"en"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10217072","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中島, 暉","creatorNameLang":"ja"},{"creatorName":"ナカジマ, アキラ","creatorNameLang":"ja-Kana"},{"creatorName":"Nakajima, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"植田, 勇人","creatorNameLang":"ja"},{"creatorName":"ウエダ, ユウト","creatorNameLang":"ja-Kana"},{"creatorName":"Ueda, Yuto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"熊田, 高之","creatorNameLang":"ja"},{"creatorName":"クマダ, タカユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒殿, 保幸","creatorNameLang":"ja"},{"creatorName":"アラトノ, ヤスユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kumada, Takayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aratono, Yasuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"jikikyometoigaku-13-47-2002.pdf","filesize":[{"value":"271.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jikikyometoigaku-13-47-2002.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/1367/files/jikikyometoigaku-13-47-2002.pdf"},"version_id":"8e9c5c87-7d53-47d5-af3c-d76bc414ecee"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"hydroxy radical, copper ion, hydrogen peroxide, microorganisms, Arthrobacter nicotianae, copper biosorption, DMPO","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"銅一過酸化水素系でのヒドロキシラジカル生成反応と該系における微生物の挙動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"銅一過酸化水素系でのヒドロキシラジカル生成反応と該系における微生物の挙動","subitem_title_language":"ja"},{"subitem_title":"Generation of hydroxyl radical in Cu(II)−H2O2 system and behavior of microorganisms in the system.","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"5","path":["72","30"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-12-05"},"publish_date":"2007-12-05","publish_status":"0","recid":"1367","relation_version_is_last":true,"title":["銅一過酸化水素系でのヒドロキシラジカル生成反応と該系における微生物の挙動"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2024-01-30T04:20:54.866153+00:00"}
