The metal-loaded bacteria has profound implications for the transfer of metals from the hydrosphere to the sediments. Microorganisms will have playd an important role in metal deposition under various temperature conditions. The microorganisms concentrate aqueous dissolved metals onto cell walls and at intracellular sites, during the life cycle, and strongly bind metals during early diagenesis. A sequence is observed in which amorphous cations concentrated at cell walls are progressively transformed to microcrystalline aggregates of carbonate, silicate, Mn-Fe oxides, and clay minerals. The bioprecipitated oxides and oxyhydroxides act as scavengers for heavy metals such as Cu, Pb, Zn, Cd, Sr, and U,in the aqueous toxic-metal dispersion environment. The biomineralization of bacterial cells has been followed in a laboratory simulation by electron microscopy and energy-dispersive X-ray spectroscopy. Several kinds of bacteria were examined for the ability to remove heavy metals from solution. SEM-EDX,TEM,XRF and XRD results indicated that most of metals accumulated at the cell surface as crystalline precipitates after several days of aging.","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:05554012, 研究期間(年度):1993–1995","subitem_description_type":"Other"},{"subitem_description":"出典：「岩石の微生物腐食の評価装置」研究成果報告書　課題番号05554012\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":"金沢大学自然科学研究科"}]},"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-05554012/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-05554012/055540121995kenkyu_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 1996-14p.pdf","filesize":[{"value":"773.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAZAKI-K-kaken 1996-14p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34898/files/SC-PR-TAZAKI-K-kaken 1996-14p.pdf"},"version_id":"5bb07ee9-34af-4fd2-8c0a-c4caf564d32f"}]},"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":"岩石の微生物腐食の評価装置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"岩石の微生物腐食の評価装置"},{"subitem_title":"Evaluational Equipment for Biological Weathering","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2838"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34898","relation_version_is_last":true,"title":["岩石の微生物腐食の評価装置"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:54:01.970152+00:00"}
