Water pumping from the cove inside the containers extended for 25 days. Diatoms were the dominant microalgae in these biofilms, which were removed from a set of tiles to a) characterize the extracellular mucilage, b) carry out floristic determination and c) perform grazing experiments with the limpet Nacella concinna. Biofilms mucilaginous matrix consisted of proteins and carbohydrates. Room temperature aqueous extraction of the freeze-dried material rendered a fraction enriched in the storage glucan chrysolaminarin, its identity confirmed by methylation structural analyses. Hot water extracted products showed greater heterogeneity in monosaccharide composition, including glucose, mannose, galactose, fucose, xylose and rhamnose. Diatom identification revealed that Pseudogomphonema kamtschaticum was the dominant species followed by several Navicula species, Nitzschia pellucida and Synedra kerguelensis. Photographical survey of colonized tiles placed in glass flasks together with a specimen of Nacella concinna exhibited between 5 and 30% removal of the biofilms coverage after 24 h of exposure to the limpet, suggesting that EPS and chrysolaminarin constitute a C-source for the gastropod.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Yasmin Daglio, Hernán Sacristán, Martín Ansaldo, María C.Rodríguez\n南極キングジョージ島、Potter Coveの海岸に陶器のタイルを設置し、25日間でのバイオフィルムの発達実験を行った。バイオフィルム中では珪藻が優占したが、そこからa）細胞外粘液質の特徴、b）植物相の同定、c）カサガイの一種Nacella concinnaを用いた囓り取り実験を行った。バイオフィルムの粘液層は、タンパク質と炭水化物からなり、グルカノ-クリソラミナリンやグルコースなどの多様な単糖類が含まれていた。珪藻を同定したところ、Pseudogomphonema kamtschaticumが優占し、Naviculaなどがそれに続く事が明らかになった。カサガイによる囓り取りは、24時間で5～30%で、EPSとクリソラミナリンは彼らの炭素源となっていることが示唆された。\n","subitem_description_type":"Other"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2018.01.004"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2018.01.004","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Daglio, Yasmin","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sacristán, Hernán","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ansaldo, Martín","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rodríguez, María C.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Benthic diatoms","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Feeding","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Gastropods","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nacella concinna","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"β-1,3-glucan","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctica Potter Cove","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"25 de Mayo (King George) Island","subitem_subject_language":"en","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":"Benthic diatoms from Potter Cove, 25 de Mayo (King George) Island, Antarctica: Mucilage and glucan storage as a C-source for limpets","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Benthic diatoms from Potter Cove, 25 de Mayo (King George) Island, Antarctica: Mucilage and glucan storage as a C-source for limpets"},{"subitem_title":"Benthic diatoms from Potter Cove, 25 de Mayo (King George) Island, Antarctica: Mucilage and glucan storage as a C-source for limpets","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"37","path":["1895"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-04"},"publish_date":"2018-04-04","publish_status":"0","recid":"14985","relation_version_is_last":true,"title":["Benthic diatoms from Potter Cove, 25 de Mayo (King George) Island, Antarctica: Mucilage and glucan storage as a C-source for limpets"],"weko_creator_id":"37","weko_shared_id":37},"updated":"2023-07-25T12:47:30.564572+00:00"}
