Even with 6- and 8-fold diluted ADE, which contained a limited amount of phosphate, the algal biomass production during a 6-day experiment reached 0.62 g/L, including higher carbohydrate but lower protein and lipid contents than cells cultivated in standard algal media. β-glucan was produced at 3 to 7 times the amount in standard algal media. Phosphate and ammonium removal efficiencies during the cultivation were > 96%. Additionally, the essential fatty acid contents of this two Arthrospira species cultivated in 8-fold diluted ADE were measured with a gas chromatography-mass spectrometry system. The low amount of phosphorus in the ADE caused accumulation of health-beneficial y-linolenic acid in the Arthrospira cells. The contents of chlorophyll a and phycocyanin were also determined. A. fusiformis cultivated in ADE contained higher amount of phycocyanin than that in standard algal medium. These results suggested that cultivating Arthrospira with ADE of water hyacinth could lead to functional food production including valuable biomolecules such as P-glucan and γ-linolenic acid, and consequently contribute to sustainable management of such nuisance aquatic macrophyte.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"世界中で過剰繁茂して環境問題となっているホテイアオイ を嫌気発酵処理し、 その消化液(ADE)を用いてArthrospira p latensisおよびA.fusiformisを培養し、それらの生化学組 成を調べた。 リン酸塩が不足気味だったにもかかわらず、6倍と8倍に希釈したADEで最も高い生産が得られ、6日間の培養で生物最は0.62 g/Lに達した。 これには、 標準的な藻類培養液で培養したものに比べて炭水化物含董が高く、 蛋白質および脂質含量が低かった。特に、β―グルカンは標準培養液のときの3~7倍高い値を示した。 これら藻類培養によるADEからのリン酸塩とアンモニアの除去率は96％を上回った。加えて、ホテイアオイ由来のADEで培養したArthrospiraに含有する必須脂肪酸組成を調べたところ、γ―リノール酸含量の増加が確認できた。クロロフィルaおよびフィコシアニン含量も調べ、 A.fusiformisでフィコシアニン含量の増加することが分かった。これらの結果は、ホテイアオイ由来のADEを用いたArthrospiraの培養が、β―グルカンや γ―リノール酸のような有用生化学物質の生産に高いポテンシャルを有し、過剰繫茂した水草の持続的な利用に寄与する可能性を示した。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_1617186702042":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617265215918":{"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_1617604990215":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-21"}],"filename":"24201k136_zenbun.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"全文","objectType":"fulltext","url":"https://usp.repo.nii.ac.jp/record/2000662/files/24201k136_zenbun.pdf"},"version_id":"84afbfc7-73c2-4e86-b8d6-486bb5473a27"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-21"}],"filename":"24201k136_yoshi.pdf","filesize":[{"value":"53 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"要旨","objectType":"summary","url":"https://usp.repo.nii.ac.jp/record/2000662/files/24201k136_yoshi.pdf"},"version_id":"e7656099-8482-4790-b39d-e7946df4164b"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-21"}],"filename":"24201k136_shinsakekka.pdf","filesize":[{"value":"58 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"審査結果","objectType":"abstract","url":"https://usp.repo.nii.ac.jp/record/2000662/files/24201k136_shinsakekka.pdf"},"version_id":"c3b0bab9-19d9-414f-8253-8b1b5b529473"}]},"item_1623818042585":{"attribute_name":"Identifier Registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24795/0002000662","subitem_identifier_reg_type":"JaLC"}]},"item_1719206165111":{"attribute_name":"学位名","attribute_value_mlt":[{"subitem_degreename":"博士（学術）","subitem_degreename_language":"ja"}]},"item_1719206202375":{"attribute_name":"学位授与機関","attribute_value_mlt":[{"subitem_degreegrantor":[{"subitem_degreegrantor_language":"ja","subitem_degreegrantor_name":"滋賀県立大学"}]}]},"item_1719206211735":{"attribute_name":"学位授与年月日","attribute_value_mlt":[{"subitem_dategranted":"2024-03-20"}]},"item_1719206220424":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第136号"}]},"item_1722321051957":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_1722583919300":{"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_1729061525552":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageStart":"1"}]},"item_title":"Biochemical compositions in two Arthrospia spices cultivated in anaerobic digestion effluent of water hyacinth, which is growing excessively worldwide","item_type_id":"40009","owner":"11","path":["1719211374765"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-21"},"publish_date":"2024-10-21","publish_status":"0","recid":"2000662","relation_version_is_last":true,"title":["Biochemical compositions in two Arthrospia spices cultivated in anaerobic digestion effluent of water hyacinth, which is growing excessively worldwide"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-10-21T02:31:18.280180+00:00"}
