With the aim of comparative study on the toxicity and toxin composition in different bivalve species, we analyzed PSP toxins in A. catenella and bivalves, mussels, oysters and short-necked clam collected at Tokuyama Port (TOK) and Kushigahama beach (KU) on May 29-30 using HPLC.Cell density of A. catenella was higher at TOK (3.3×104 cells/ml) than at KU (2.7×102 cells/ ml). Natural A. catenella collected at TOK produced PSP toxins at the content of 31.06 fmol/cell (equivalent for 0.166 MU/104 cells). The dominant components of PSP toxins were C1+C2 and GTX4, which were included respectively 80.4 mol% and 13.7 mol% of total toxins. The toxicity of mussel (108.6 MU/g) was higher than oyster (13.8 MU/g), although both bivalves inhabited same environmental condition at TOK. There was same tendency at KU (67.9 MU/g and 7.4 MU/g in mussel and oyster, respectively). The oyster collected at TOK showed lower toxicity than short-necked clam (35.1 MU/g), while the toxin content was more. The dominant toxins were C1+C2 in all species. The ratios of potent toxic carbamoyl derivatives, GTX1-4, neoSTX and STX, were higher in mussels and clam than A. catenella, but the ratios of these toxins were lower in oysters. The toxin composition were different among the species, but were similar between same species at different stations. These results indicate that not only toxin content but also the specific accumulation and metabolism of toxins in bivalves affect the difference of toxicity.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"瀬戸内海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Research Institute of Fisheries and Environment of Inland Sea","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"seto_k_105","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010611633","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA1138042X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"1344-8579","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"坂本, 節子","creatorNameLang":"ja"}],"familyNames":[{"familyName":"坂本","familyNameLang":"ja"}],"givenNames":[{"givenName":"節子","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"長崎, 慶三","creatorNameLang":"ja"}],"familyNames":[{"familyName":"長崎","familyNameLang":"ja"}],"givenNames":[{"givenName":"慶三","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"松山, 幸彦","creatorNameLang":"ja"}],"familyNames":[{"familyName":"松山","familyNameLang":"ja"}],"givenNames":[{"givenName":"幸彦","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"小谷, 祐一","creatorNameLang":"ja"}],"familyNames":[{"familyName":"小谷","familyNameLang":"ja"}],"givenNames":[{"givenName":"祐一","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"paralytic shellfish poisoning; toxicity; toxin composition; Alexandrium catenella; bivalves","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"徳山湾に発生したAlexandrium catenella赤潮による二枚貝類の毒化 －麻痺性貝毒の毒性および毒成分組成の比較－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"徳山湾に発生したAlexandrium catenella赤潮による二枚貝類の毒化 －麻痺性貝毒の毒性および毒成分組成の比較－","subitem_title_language":"ja"},{"subitem_title":"Comparison of Toxicity and Toxin Composition among Bivalves Affected with PSP Toxins by the Red Tide of Alexandrium catenella in Tokuyama Bay","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-22"},"publish_date":"2024-04-22","publish_status":"0","recid":"2002393","relation_version_is_last":true,"title":["徳山湾に発生したAlexandrium catenella赤潮による二枚貝類の毒化 －麻痺性貝毒の毒性および毒成分組成の比較－"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-09T09:03:55.760426+00:00"}
