In this treatment the plaster wall is repeatedly cleaned and consolidated.\nNowadays,some enzymes are applied in a novel cleaning method to decompose and remove fungi or stain from mural paintings. This method aims to release and break down the components of the fungi or stains. After that,the painting surface is wiped with water and consolidated for support again.\n In this study, the effect of enzymes,which may remain on mural paintings even after cleaning, on consolidants was investigated. Six enzymes were chosen for cleaning: Proteinase K for decomposition of protein;Achromopeptidase and Lysozyme, which are cell wall lytic enzymes for decomposition of biofilm formed by bacteria;Lysing Enzymes, ZymolyaseⓇ and Yatalase™,which are cell wall lytic enzymes for decomposition of fungi or yeast.\n As a result of analysis of the changes in the characterization of purified funori and MC, it was found that these consolidants were affected by some of the enzymes. Purified funori was affected by Protainase K,Lysozyme,Lysing Enzymes,ZymolyaseⓇ and Yatalase™. It aggregated and produced a white substance after 24 hours’reaction with each enzyme. Especially Lysozyme responded to funori significantly, causing high aggregation in a few seconds. ZymolyaseⓇ, Lysing Enzymes and Yatalase™ reduced the molecular weight of the polymer components in funori after 7 days. This means that polymers in funori were broken down to smaller sizes. Both 400cps MC and 4000cps MC, when they reacted with Lysing Enzymes,ZymolyaseⓇ and Yatalase™ respectively,yielded white turbidity after 5 days. When MC was reacted with Proteinase K,a strong smell was produced. In addition, Achromopeptidase and Lysing Enzymes reduced the molecular weight of MC after 24 hours’reaction.\n From these results, it is suggested that Achromopeptidase is appropriate for cleaning mural paintings when funori is used as a consolidant,while Lysozyme is suitable when MC is used as a consolidant.","subitem_description_type":"Abstract"}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18953/00003841","subitem_identifier_reg_type":"JaLC"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"貴田, 啓子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"早川, 典子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 嘉則"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大河原, 典子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"和田, 朋子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"五十嵐, 圭日子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木川, りか"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川野邊, 渉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Keiko, KIDA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Noriko, HAYAKAWA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshinori, SATO","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Noriko, OKAWARA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"\\nTomoko, WADA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kiyohiko, IGARASHI","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rika, KIGAWA\\n","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wataru, KAWANOBE","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":"2017-07-31"}],"displaytype":"detail","filename":"05202.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"05202.pdf","url":"https://tobunken.repo.nii.ac.jp/record/3851/files/05202.pdf"},"version_id":"6ba39a29-a6a0-44ba-a76e-76b2b84c5d2f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"フノリ","subitem_subject_scheme":"Other"},{"subitem_subject":"壁画","subitem_subject_scheme":"Other"},{"subitem_subject":"修復","subitem_subject_scheme":"Other"},{"subitem_subject":"接着材料","subitem_subject_scheme":"Other"},{"subitem_subject":"酵素","subitem_subject_scheme":"Other"},{"subitem_subject":"enzyme; mural painting; restoration; consolidant; funori","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"〔報文〕壁画修復に用いる接着材料の分子量および強度の変化に及ぼす酵素の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"〔報文〕壁画修復に用いる接着材料の分子量および強度の変化に及ぼす酵素の影響"},{"subitem_title":"Effect of Enzymes on the Molecular Weight or Strength of Consolidants Used in the Conservation of Mural Paintings","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["526"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-31"},"publish_date":"2017-07-31","publish_status":"0","recid":"3851","relation_version_is_last":true,"title":["〔報文〕壁画修復に用いる接着材料の分子量および強度の変化に及ぼす酵素の影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T15:48:13.893983+00:00"}
