A further increase in bioethanol production may come from lignocellulosic biomass, such as agricultural residues and wood. Lignocellulose from waste products is abundant, inexpensive, and renewable. Cellulose, which is a homopolysaccharide composed of β-D-glucopyranose units linked by β-1,4 glycosidic bonds, comprises around 40-50 wt.% of plant biomass. One of the best known cellulose decomposers is termite, which is able to hydrolyze 74-99% of the cellulose ingested. Taking advantage of this high efficiency with which termites digest cellulose, and due to the essentiality of β-glucosidase catalyzing the hydrolysis of cellobiose or cello-oligomers into the fermentable sugar, glucose, in the process of cellulose degradation, the objective of this work is to heterologously express, purify, characterize, and compare three endogenous glycoside hydrolase family 1 (GH1) β-glucosidases from termites. Further comparison was done with the commercial β-glucosidase Novozym 188. In addition, the effect of addition of termite β-glucosidases or Novozym 188 to Celluclast 1.5 L on the degradation of Avicel was studied. This work might introduce alternative and efficient enzymes to the bioethanol production field.","subitem_description_type":"Abstract"}]},"item_7_dissertation_number_26":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第28064号"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"11518","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ウチマ, クリスチアーネ アケミ"}]}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00005521","subitem_identifier_reg_type":"JaLC"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"doctoral"}]},"item_7_subject_13":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"464","subitem_subject_scheme":"NDC"}]},"item_7_text_22":{"attribute_name":"学位分野","attribute_value_mlt":[{"subitem_text_value":"Agriculture (農学)"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"Department of Biotechnology, Graduate School of Agricultural and Life Sciences (農学生命科学研究科応用生命工学専攻)"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"博農第3780号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科応用生命工学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uchima, Cristiane Akemi"}],"nameIdentifiers":[{"nameIdentifier":"11517","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-01"}],"displaytype":"detail","filename":"39-097048.pdf","filesize":[{"value":"5.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"39-097048.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/5530/files/39-097048.pdf"},"version_id":"62b1df92-a69f-4676-9a0e-3a87adbe366e"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"A study on endogenous beta-glucosidases from termites and their applicability in biomass conversion","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A study on endogenous beta-glucosidases from termites and their applicability in biomass conversion"}]},"item_type_id":"7","owner":"1","path":["280","285"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-24"},"publish_date":"2014-02-24","publish_status":"0","recid":"5530","relation_version_is_last":true,"title":["A study on endogenous beta-glucosidases from termites and their applicability in biomass conversion"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:49:53.184362+00:00"}
