We optimized lignin extraction conditions to utilize the solid residue as a source of alkali-soluble lignin (ASL). An increase in NaOH concentration in the range of 25–150 mM led to a increase in the extraction efficiency of ASL dose dependently. Time-course analysis of ASL  solubilization showed that the extraction efficiency of ASL of unpretreated Erianthus increased in a time-dependent manner. In contrast, a large amount of ASL was extracted immediately after NaOH was added to the solid residue, suggesting that ASL in the solid residue had already been  partially degraded in the Ca(OH)2-treated process. The contaminates, such as glucan and xylan in the solid residue was only one-tenth of that of the unpretreated Erianthus. These data suggested that the solid residue was preferable as a lignin source to unpretreated Erianthus in terms of the degree of purity.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00000056","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人 農業・食品産業技術総合研究機構"},{"subitem_publisher":"National Agriculture and Food Research Organization (NARO)"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2432-7891","subitem_source_identifier_type":"ISSN"}]},"item_10002_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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山岸, 賢治"},{"creatorName":"ヤマギシ, ケンジ","creatorNameLang":"ja-Kana"},{"creatorName":"YAMAGISHI, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"趙, 鋭"},{"creatorName":"チョウ, エイ","creatorNameLang":"ja-Kana"},{"creatorName":"ZHAO, Rui","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"池, 正和"},{"creatorName":"イケ, マサカズ","creatorNameLang":"ja-Kana"},{"creatorName":"IKE, Masakazu","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"関, 笛"},{"creatorName":"カン, テキ","creatorNameLang":"ja-Kana"},{"creatorName":"GUAN, Di","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"我有, 満"},{"creatorName":"ガウ, ミツル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"徳安, 健"},{"creatorName":"トクヤス, ケン","creatorNameLang":"ja-Kana"},{"creatorName":"TOKUYASU, Ken","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-08-22"}],"displaytype":"detail","filename":"nfri_report01-13p.pdf","filesize":[{"value":"692.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nfri_report01-13p.pdf","url":"https://repository.naro.go.jp/record/66/files/nfri_report01-13p.pdf"},"version_id":"7f74dff6-7d42-4163-90cc-f78150d69fcd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CaCCO process","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Erianthus","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solid residue","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"alkali-soluble lignin","subitem_subject_language":"en","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":"CaCCO プロセス由来糖化後残渣からのアルカリ可溶性リグニン抽出条件最適化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CaCCO プロセス由来糖化後残渣からのアルカリ可溶性リグニン抽出条件最適化"},{"subitem_title":"Optimization of extraction efficiency of alkali soluble lignin from solid residue derived from CaCCO process","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["32","45"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-22"},"publish_date":"2017-08-22","publish_status":"0","recid":"66","relation_version_is_last":true,"title":["CaCCO プロセス由来糖化後残渣からのアルカリ可溶性リグニン抽出条件最適化"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T16:05:35.207791+00:00"}
