These facts suggest that the causative plankton species for domoic acid occur widely in tropical waters and that Spondylus spp. accumulate domoic acid more effectively than other bivalve species. In the monitoring on seasonal change of domoic acid levels in S. vesicolor and plankton net samples in Nha Phu Bay, Vietnam, domoic acid level of S. versicolor was found to increase when domoic acid was detected in the plankton net samples. Under light microscopic observation of the plankton samples, cells of Pseudo-nitzschia spp., the size of which was smaller than toxic Pseudo-nitzschia such as P. multiseries, were observed. When the plankton net samples were fractionated by successive filtration through the sieves and membrane filters with different pore sizes, most of the domoic acid was recovered in the particle fraction with smallest size (0.6-10μm). Some strains of unicellular cultures established from the cells in this fraction showed the production of domoic acid, though the productivity was low. All the domoic acid-producing strains seemed to be the same species. These results indicate that Pseudo-nitzschia species is also causative for domoic acid in tropical bivalves.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Proceedings of the Horiba International Conference \"New Direction of Ocean Research in the Western Pacific\" : Past, Present and Future of UNESCO/IOC/WESTPAC Activity for 50 years and the JSPS Project \"Coastal Marine Science\"","subitem_description_type":"Other"},{"subitem_description":"Section I: Research Articles/Harmful microalgae","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040627","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, Atmosphere and Ocean Research Institute, the University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11957899","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13493000","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"東京大学大気海洋研究所国際沿岸海洋研究センター"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Institute of Oceanography"},{"subitem_text_value":"Asian Natural Environment Science Center, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Dao, Viet Ha"}],"nameIdentifiers":[{"nameIdentifier":"93348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Omura, Takuo"}],"nameIdentifiers":[{"nameIdentifier":"93349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takata, Yoshinobu"}],"nameIdentifiers":[{"nameIdentifier":"93350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pham, Xuan Ky"}],"nameIdentifiers":[{"nameIdentifier":"93351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuyo, Yasuwo"}],"nameIdentifiers":[{"nameIdentifier":"93352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kodama, Masaaki"}],"nameIdentifiers":[{"nameIdentifier":"93353","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":"2017-06-14"}],"displaytype":"detail","filename":"CMS350102.pdf","filesize":[{"value":"635.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CMS350102.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40636/files/CMS350102.pdf"},"version_id":"a3dd0604-0140-4b9f-bf83-259cb8870c62"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"domoic acid","subitem_subject_scheme":"Other"},{"subitem_subject":"amnesic shellfish poisoning","subitem_subject_scheme":"Other"},{"subitem_subject":"Pseudo-nitzschia sp.","subitem_subject_scheme":"Other"},{"subitem_subject":"Spondylus","subitem_subject_scheme":"Other"},{"subitem_subject":"tropical bivalve","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Pseudo-nitzschia species, a possible causative organism of domoic acid in Spondylus versicolor collected from Nha Phu Bay, Khanh Hoa Province, Vietnam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pseudo-nitzschia species, a possible causative organism of domoic acid in Spondylus versicolor collected from Nha Phu Bay, Khanh Hoa Province, Vietnam"}]},"item_type_id":"4","owner":"1","path":["7183","7181"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-25"},"publish_date":"2012-05-25","publish_status":"0","recid":"40636","relation_version_is_last":true,"title":["Pseudo-nitzschia species, a possible causative organism of domoic acid in Spondylus versicolor collected from Nha Phu Bay, Khanh Hoa Province, Vietnam"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:15:57.343161+00:00"}
