A hydroxyl radical is formed in the solution through two steps, the reduction of Cu（II） to Cu（I） by H2O2 and the Fenton-type reaction of Cu（I） with H2O2. The resultant radical is trapped by DMPO to form DMPO-OH. Microbial cells retarded the DMPO-OH in the Cu（II）-H2O2-DMPO far more significantly than in the UV-irradiated H2O2- DMPO solution. Egg albumin showed a higher DMPO-OH retardation than microbial cells both in the Cu（II）-H2O2-DMPO and the UV-irradiated H2O2-DMPO solutions. These results indicated that the retardation effect is related to organic matter and not to microbial activity.\nMicroorganisms having higher affinities for copper ion retarded DMPO-OH more\nsignificantly. The linear relationship between the amounts of copper biosorption and the inverse of the median inhibitory doses for DMPO-OH indicated that the microbial cells inhibited the reduction of Cu（II） to Cu（I） by H2O2, followed by the decrease of hydroxyl radical formation and the retardation of DMPO-OH. These results also suggest that the coupling between microbial cells and Cu（II） ion can be estimated from their ability to retard\nDMPO-OH.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"The original publication is available at www.springerlink.com","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer","subitem_publisher_language":"en"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10811107","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09593993","subitem_source_identifier_type":"ISSN"}]},"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":"Nakajima, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7727","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ueda, Yuto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8016","nameIdentifierScheme":"WEKO"}]}]},"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":"WorldJMicrobiolBiotechnol-inpress.pdf","filesize":[{"value":"232.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"WorldJMicrobiolBiotechnol-inpress.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/1432/files/WorldJMicrobiolBiotechnol-inpress.pdf"},"version_id":"02ff4a5d-ba30-4d62-b9d6-8b0e083c90f9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"copper biosorption, Cu(II) ion, DMPO, DMPO-OH, hydrogen peroxide, hydroxyl radical elimination","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Relationship between copper biosorption and microbial inhibition of hydroxyl radical formation in a copper(II)–hydrogen peroxide system","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Relationship between copper biosorption and microbial inhibition of hydroxyl radical formation in a copper(II)–hydrogen peroxide 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":"1432","relation_version_is_last":true,"title":["Relationship between copper biosorption and microbial inhibition of hydroxyl radical formation in a copper(II)–hydrogen peroxide system"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2024-05-27T04:05:50.382083+00:00"}
