Water temperature, diatom cell density, illumination intensity, time, and handling stress during pre-treatment were analyzed as explanatory variables that could affect the specific growth rates of the diatom during culture, using linear mixed-effects models. The results indicated that water temperature was the only significant explanatory factor（p<0.001） in the best model for the short-term expansion culture of the diatom. Growth to approximately 100×104 cells/mL, which was 12 times the initial diatom density（8×104 cells/mL）, was observed under continuous lighting and a constant water temperature （20 ºC） during three days of culture after performing seeding of the original strains into acclimation water （20 ºC）. Simplification of this process and the cost of the culture were also evaluated.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"冬季における浮遊珪藻 Chaetoceros neogracile 市販濃縮製品を元株とした大量培養法を検討した。浮遊珪藻の培養時の比増殖速度に影響を与える前処理時の水温，細胞密度，水面照度，処理時間および培養直前のハンドリングを説明変数として線形混合効果モデルにより解析した。その結果，最適モデルの要因は水温のみで，有意（p < 0.001）であると結論づけられた。元株を水温 20 ºC で馴致処理後，20 ºC を維持して 3 日間高圧ナトリウムランプを連続照射する培養により，細胞密度（8× 104cells/mL）は，約 100 × 104cells/mL まで 12 倍に増加した。培養の省力化とコストについても検討した。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research and Education Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_t_9_1_1","subitem_relation_type_select":"Local"}}]},"item_10001_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/2010912190","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"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_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":"山田, 徹生","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山田","familyNameLang":"ja"}],"givenNames":[{"givenName":"徹生","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"兼松, 正衛","creatorNameLang":"ja"}],"familyNames":[{"familyName":"兼松","familyNameLang":"ja"}],"givenNames":[{"givenName":"正衛","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-06"}],"filename":"fra_t_9_1_1.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010579/files/fra_t_9_1_1.pdf"},"version_id":"5285ecc1-5b25-451d-9367-238f93936a24"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"浮遊珪藻 Chaetocerosneogracile; 冬季大量培養; 市販濃縮製品; 無脊椎動物餌料","subitem_subject_language":"ja","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"冬季における浮遊珪藻Chaetoceros neogracile市販濃縮製品を元株とした低コスト大量培養法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"冬季における浮遊珪藻Chaetoceros neogracile市販濃縮製品を元株とした低コスト大量培養法","subitem_title_language":"ja"},{"subitem_title":"Low-cost mass culture method using the commercial diatom Chaetoceros neogracile as an original strain seed during winter","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085691519"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010579","relation_version_is_last":true,"title":["冬季における浮遊珪藻Chaetoceros neogracile市販濃縮製品を元株とした低コスト大量培養法"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:39:32.938275+00:00"}
