Microorganisms contribute particularly to the fixation of tremendous range of metals and minerals in contaminated areas. There are many examples of microbial remediation in the modern environments. In this projects, the mechanism of microorganisms for remediation of metal fixation is investigated for various cases, such as mining area, hot springs, sediments, and weatherd granit, by using electron microscopical techniques. Microorganisms exhibit a profound ability to bind metallic ions of Fe, Mn, Cu, U,and As, and this allows cell to serve directly as nucleation sites for biominerals. The biomineral deposits in bacterial intra-or extra-cell are shaped as crystals with a well-defined structure. The remediation appear applicable to a wide range of contaminants in natural environments. The results of biomineralization in the earth environmental system are reported in various international and national journals.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:04453052, 研究期間(年度):1992–1994","subitem_description_type":"Other"},{"subitem_description":"出典：「バクテリアによる生体鉱物の生成機構」研究成果報告書　課題番号04453052\n(KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理学部 / 島根大学"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=80211358","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-04453052/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-04453052/044530521994kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"SC-PR-TAZAKI-K-kaken 1995-13p.pdf","filesize":[{"value":"476.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAZAKI-K-kaken 1995-13p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34906/files/SC-PR-TAZAKI-K-kaken 1995-13p.pdf"},"version_id":"9ddbe4e5-5ca1-4d2c-a506-0789a3c6a67f"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"バクテリアによる生体鉱物の生成機構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"バクテリアによる生体鉱物の生成機構"},{"subitem_title":"Bacterial Biomineralization and the Mechanism","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2839"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34906","relation_version_is_last":true,"title":["バクテリアによる生体鉱物の生成機構"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:46:59.608947+00:00"}
