On the other hand, autotrophic bacteria which proliferate in the anoxic condition may partially contribute to biological production in the bay, as food source for the heterotrophs inhabiting outside the hypoxic water mass. In this study, we\ninvestigated whether the organic matter derived from photosynthetic sulfur bacteria, a species of anaerobic autotrophic bacteria which were incubated from the bottom sediment in the Omura Bay, were actually assimilated by benthic filter feeders, based on the stable isotopes (13C, 15N)-labeled techniques. First, 13C, 15N-labeled bacteria were fed to a bivalve, Anadara broughtonii. And carbon (C) and nitrogen (N)\nassimilation rates were determined, and compared with the results from the control experiments in which labeled phytoplankton were fed. The assimilations of bacteria-derived organic C and N into the muscle tissue in A. broughtonii were surely confirmed, although the assimilation rates were greatly smaller than those of phytoplankton-derived organic matter (i.e., 1/36 for C, 1/6 for N). The lower\nassimilation rate of C compared with N in either of the food sources (i.e., 50% in case of phytoplankton, and 10% bacteria) suggested that newly incorporated C was promptly metabolized as respiratory\nsubstrate. The results of this study suggested that an increase in the biomass of anaerobic autotrophic bacteria associated with hypoxic water mass contributes to biological production in the inner bay as\none of food sources.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, 97, pp.11-17; 2016","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"14223","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ichikawa, Yoshitaka"}]},{"nameIdentifiers":[{"nameIdentifier":"14224","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Umezawa, Yu"}]},{"nameIdentifiers":[{"nameIdentifier":"14225","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamaki, Kunitsugu"}]},{"nameIdentifiers":[{"nameIdentifier":"14226","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shimatsuka, Momoko"}]},{"nameIdentifiers":[{"nameIdentifier":"14227","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Wada, Minoru"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"02"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"The Faculty of Fisheries, Nagasaki University"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"市川, 好貴"}],"nameIdentifiers":[{"nameIdentifier":"14218","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梅澤, 有"}],"nameIdentifiers":[{"nameIdentifier":"14219","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山喜, 邦次"}],"nameIdentifiers":[{"nameIdentifier":"14220","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島塚, 桃子"}],"nameIdentifiers":[{"nameIdentifier":"14221","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"和田, 実"}],"nameIdentifiers":[{"nameIdentifier":"14222","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":"2020-12-21"}],"displaytype":"detail","filename":"suisan97_11.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan97_11.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/3208/files/suisan97_11.pdf"},"version_id":"36624548-7614-4b7c-8cbd-1a8ced3934aa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"嫌気性独立栄養細菌","subitem_subject_scheme":"Other"},{"subitem_subject":"anaerobic autotrophic bacteria","subitem_subject_scheme":"Other"},{"subitem_subject":"光合成硫黄細菌","subitem_subject_scheme":"Other"},{"subitem_subject":"photosynthetic sulfur bacteria","subitem_subject_scheme":"Other"},{"subitem_subject":"貧酸素水塊","subitem_subject_scheme":"Other"},{"subitem_subject":"hypoxic water mass","subitem_subject_scheme":"Other"},{"subitem_subject":"濾過食動物","subitem_subject_scheme":"Other"},{"subitem_subject":"filter feeders","subitem_subject_scheme":"Other"},{"subitem_subject":"安定同位体標識","subitem_subject_scheme":"Other"},{"subitem_subject":"stable isotopes labeling","subitem_subject_scheme":"Other"},{"subitem_subject":"閉鎖性内湾","subitem_subject_scheme":"Other"},{"subitem_subject":"semi-closed bay","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"閉鎖性内湾における光合成硫黄細菌由来有機物の高次捕食者への転送に関する基礎的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"閉鎖性内湾における光合成硫黄細菌由来有機物の高次捕食者への転送に関する基礎的研究"}]},"item_type_id":"3","owner":"2","path":["229"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-04-21"},"publish_date":"2016-04-21","publish_status":"0","recid":"3208","relation_version_is_last":true,"title":["閉鎖性内湾における光合成硫黄細菌由来有機物の高次捕食者への転送に関する基礎的研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:35:50.833429+00:00"}
