The bow, after being drifting for 4 days, was wrecked off Anto, Mikuni town, Fukui Prefecture, threatened throughout the various shores of Ishikawa Prefecture geographically as well. Shore damage by oil washing was observed by aerial research of K. Tazaki, as of 8 Feb. 1997. An oil layer at the shore of Mikuni Town reached over 50 cm in thickness. We conducted field surveys in order to examine the conditions of heavy oil washing ashore on the Ishikawa coastline, in this accident, remarkable microbial remediation research had been advanced. In fact, hydrocarbon-degrading microbes were found in each polluted area of the near-shore environments. Hydrocarbon-utilizing bacteria isolated from coastal areas. Local degrader bacteria inhibited everywhere with many kinds of species. Each species carries a role ta resolve heavy oil under the local conditions. That is a key to understand the sustainable \"bioremediation \" for polluted local area. After 5 years of spilled accident, degrader bacteria were still alive to keep the activity.","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:11354006, 研究期間(年度):1999–2002","subitem_description_type":"Other"},{"subitem_description":"出典：「重油汚染環境における微生物の環境修復法の研究」研究成果報告書　課題番号11354006\n　　　本文データは著者版報告書より作成\n","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00034796","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理学部"}]},"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-11354006/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-11354006/113540062002kenkyu_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 2003-7p.pdf","filesize":[{"value":"316.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAZAKI-K-kaken 2003-7p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34809/files/SC-PR-TAZAKI-K-kaken 2003-7p.pdf"},"version_id":"bbcbd317-bf05-4451-928a-48f3cb346179"}]},"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":"重油汚染環境における微生物の環境修復法の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"重油汚染環境における微生物の環境修復法の研究"},{"subitem_title":"Heavy oil pollution and the bioremediation methods - Heavy oil spilled from the wrecked Russian tanker \"Nakhodka\" attacked the coasts of Hokuriku district in 1997 -","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2831"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34809","relation_version_is_last":true,"title":["重油汚染環境における微生物の環境修復法の研究"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:41:30.454362+00:00"}
