The tensile strength of chitin films was 30～40％ lower than that of chitosan films, but the crystallinity of chitin film was much higher than that of chitosan films. The crystallinity and orientation of crystallites were hardly affected by the four kinds of solvent chosen to cast chitosan films, but a detailed analysis revealed that the cast film prepared with acetic acid provided slightly lower crystallinity than others. The antibacterial activities of quaternary chitosan films against Staphylococcus aureus NBRC 12732 and Escherichia coli NBRC 3972 were stronger than those of chitosan films. The antibacterial activities of neutralized chitosan films may be slightly inferior to those of unneutralized chitosan films. The improvement in the antibacterial activity of chitosan films against E. coli was slightly inferior to that against S. aureus. This phenomenon was particularly observed on the neutralized chitosan films. Though the antibacterial activity of chitosan was slightly inferior to that of the organic antibacterial compounds, we emphasize that chitosan would be a useful and suitable material with regard to its effect on the environmental ecosystem.","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学資源再生研究所"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"NAKASHIMA, Teruo"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学資源再生研究所"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Institute of Resource Recycling, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","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":"中島,  照夫"},{"creatorName":"ナカシマ, テルオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-19"}],"displaytype":"detail","filename":"AA1247496X-20090331-0001.pdf","filesize":[{"value":"6.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1247496X-20090331-0001.pdf","url":"https://kindai.repo.nii.ac.jp/record/13106/files/AA1247496X-20090331-0001.pdf"},"version_id":"a3e92b41-ccf4-4de8-8f05-16b474e18610"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"chitosan and quaternary chitosan films","subitem_subject_scheme":"Other"},{"subitem_subject":"physical property of chitosan","subitem_subject_scheme":"Other"},{"subitem_subject":"antibacterial efficacy","subitem_subject_scheme":"Other"},{"subitem_subject":"Film Adhering Method (JIS Z 2801^<:2002>)","subitem_subject_scheme":"Other"},{"subitem_subject":"Staphylococcus aureus NBRC 12732","subitem_subject_scheme":"Other"},{"subitem_subject":"Escherichia coli NBRC 3972","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":"生分解性材料としてのキトサンフィルムの物性と抗菌活性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"生分解性材料としてのキトサンフィルムの物性と抗菌活性"}]},"item_type_id":"2","owner":"3","path":["2205","3774"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-12"},"publish_date":"2011-07-12","publish_status":"0","recid":"13106","relation_version_is_last":true,"title":["生分解性材料としてのキトサンフィルムの物性と抗菌活性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T23:18:56.573129+00:00"}
