The fatty acid composition of four species of Ulvaceae (U. fasciata, U. pertusa, U. arasakii and U. conglobota) was analyzed by capillary gas chromatography to investigate the relationship with the algicidal activity. The results indicate that highly algicidal species, U. fasciata and U. pertusa, showed higher contents of C16:4 n-3, C18:3 n-3, and C18:4 n-3. Concentrations of these PUFAs released from the seaweed in the culture medium were also analyzed. These PUFAs were found to be significantly active against Chattonella antiqua, C. marina, Fibrocapsa japonica, Heterosigma akashiwo, Karenia mikimotoi, moderately effective against Heterocapsa circularisquama, Prorocentrum minimum, P. sigmoides, Scrippsiella trochoidea, whereas low effective against Alexandrium catenella and Cochlodinium polykrikoides. It is suggested that the PUFAs are useful mitigation agents to remove several harmful effects without causing detrimental effects on surrounding marine living organisms.", "subitem_description_type": "Abstract"}]}, "item_2_description_63": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "Journal of Applied Phycology, 20(5), pp.713-720; 2009", "subitem_description_type": "Other"}]}, "item_2_publisher_33": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Springer Netherlands"}]}, "item_2_relation_12": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1007/s10811-007-9257-5", "subitem_relation_type_select": "DOI"}}]}, "item_2_rights_13": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "c Springer Science+Business Media B.V. 2007"}, {"subitem_rights": "The original publication is available at www.springerlink.com"}]}, "item_2_source_id_10": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10729877", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09218971", "subitem_source_identifier_type": "ISSN"}]}, "item_2_source_id_8": {"attribute_name": "EISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1573-5176", "subitem_source_identifier_type": "ISSN"}]}, "item_2_version_type_16": {"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": "Alamsjah, Mochammad Amin"}], "nameIdentifiers": [{"nameIdentifier": "62043", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hirao, Shotaro"}], "nameIdentifiers": [{"nameIdentifier": "62044", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishibashi, Fumito"}], "nameIdentifiers": [{"nameIdentifier": "62045", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Oda, Tatsuya"}], "nameIdentifiers": [{"nameIdentifier": "62046", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fujita, Yuji"}], "nameIdentifiers": [{"nameIdentifier": "62047", "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": "2020-12-23"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "JAP20_713.pdf", "filesize": [{"value": "188.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 188100.0, "url": {"label": "JAP20_713.pdf", "url": "https://nagasaki-u.repo.nii.ac.jp/record/16384/files/JAP20_713.pdf"}, "version_id": "0e9438c8-db7f-45b7-a0d0-a0f71cf63a93"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Algicidal compound", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Red tide phytoplankton", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ulva fasciata", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ulva pertusa", "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": "Algicidal activity of polyunsaturated fatty acids derived from Ulva fasciata and U. pertusa (Ulvaceae, Chlorophyta) on phytoplankton", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Algicidal activity of polyunsaturated fatty acids derived from Ulva fasciata and U. pertusa (Ulvaceae, Chlorophyta) on phytoplankton"}]}, "item_type_id": "2", "owner": "2", "path": ["315"], "permalink_uri": "http://hdl.handle.net/10069/22263", "pubdate": {"attribute_name": "公開日", "attribute_value": "2009-10-20"}, "publish_date": "2009-10-20", "publish_status": "0", "recid": "16384", "relation": {}, "relation_version_is_last": true, "title": ["Algicidal activity of polyunsaturated fatty acids derived from Ulva fasciata and U. pertusa (Ulvaceae, Chlorophyta) on phytoplankton"], "weko_shared_id": 2}
