Arthrospira, a protein-rich cyanobacterium, could enhance nutrition through biomass production, but its use as food in Ethiopian soda lakes is underexplored. This study involved morphological isolation, growth rate screening, 16S rRNA identification, and biochemical analysis of Arthrospira-like isolates (Chapter II, Study 1). It was followed by an evaluation of the effects of varying simulated light conditions (full sunlight, greenhouse, mid-day shade in a greenhouse, and full-time shade in a greenhouse) on the growth and biochemical composition of Limnospira fusiformis strain LC-30, selected from Study 1 (Chapter III, Study 2). A total of 100 Arthrospira-like strains were isolated, with four strains exhibiting the highest specific growth rates selected for molecular identification, all confirmed as Limnospira fusiformis. These strains underwent biomass screening and biochemical analysis, showing results consistent with previous studies. Notably, strains LC-30 and LA-08 exhibited high protein and phycocyanin contents (Study1). Whole-time shade resulted in the highest protein (64.80% ash-free dry weight)  and phycocyanin content (97.20 mg g⁻¹). The two-stage cultivation method for phycocyanin demonstrated a 32.7% increase in content compared to the simulated study (study 2). Identifying fast-growing Limnospira fusiformis strains and optimizing light conditions for maximizing biomass, phycocyanin and nutritional value highlights the potential of indigenous strains as nutritional supplements.","subitem_description_type":"Abstract"}]},"item_4_dissertation_number_11":{"attribute_name":"dissertation_number","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第221号"}]},"item_4_version_type_14":{"attribute_name":"出版タイプ","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":"Ayirkm, Adugna Woldie","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"アイリケム, アデューニ ウェルディ","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-03-25"}],"displaytype":"detail","filename":"rikogakukenkyuka_Ayirkm-Adugna-Woldie(sinsa).pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"rikogakukenkyuka_Ayirkm-Adugna-Woldie(sinsa).pdf","url":"https://soka.repo.nii.ac.jp/record/2000416/files/rikogakukenkyuka_Ayirkm-Adugna-Woldie(sinsa).pdf"},"version_id":"6d5ff295-5c08-4b3b-ad8c-9e739d60e86f"},{"accessrole":"open_access","date":[{"dateValue":"2024-03-25"}],"displaytype":"detail","filename":"rikogakukenkyuka_Ayirkm-Adugna-Woldie(yosi).pdf","filesize":[{"value":"426.6 KB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"rikogakukenkyuka_Ayirkm-Adugna-Woldie(yosi).pdf","url":"https://soka.repo.nii.ac.jp/record/2000416/files/rikogakukenkyuka_Ayirkm-Adugna-Woldie(yosi).pdf"},"version_id":"90e39181-d7f3-4676-89a0-dace385ffa0e"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2024-03-25"}],"displaytype":"detail","filename":"rikogakukenkyuka_Ayirkm-Adugna-Woldie(zen).pdf","filesize":[{"value":"3.7 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"rikogakukenkyuka_Ayirkm-Adugna-Woldie(zen).pdf","objectType":"fulltext","url":"https://soka.repo.nii.ac.jp/record/2000416/files/rikogakukenkyuka_Ayirkm-Adugna-Woldie(zen).pdf"},"version_id":"b9539e10-1cec-4a7e-a73e-7a6f9797dcb4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Biochemical composition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Limnospira fusiformis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"molecular identification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nutritional supplementation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"simulated outdoor light","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Shading strategies","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Molecular identification and cultivation of indigenous Limnospira strains from Ethiopian soda lakes: Growth evaluation under simulated outdoor light conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Molecular identification and cultivation of indigenous Limnospira strains from Ethiopian soda lakes: Growth evaluation under simulated outdoor light conditions","subitem_title_language":"en"},{"subitem_title":"エチオピアのソーダ湖に生息するリムノスピラ属菌株の分子同定と培養、模擬屋外光条件下での成長評価","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"14","path":["7943"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-25"},"publish_date":"2024-03-25","publish_status":"0","recid":"2000416","relation_version_is_last":true,"title":["Molecular identification and cultivation of indigenous Limnospira strains from Ethiopian soda lakes: Growth evaluation under simulated outdoor light conditions"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2025-03-25T03:10:46.508706+00:00"}
