It has the environmental toxicity and is soluble in water; therefore, it is very important to develop an easily measurable method for methanethiol in aqueous solutions. In this series of research, a fast and convenient analytical method was developed and applied to determine the concentration of methanethiol in aqueous solutions. It is based on the Ellman reaction, a reaction of methanethiol with 5,5'-dithiobis(2-nitrobenzoic acid)(DTNB), and the measurement of the absorbance of the product, namely quinoid anion, at 412 nm. The concentration of methanethiol was directly proportional to the absorbance at 412 nm, and a linear standard calibration curve was obtained in a certain range of concentration. In this research, an applicability of the new measurement method for the screening of methanethiol degrading bacteria was evaluated and it was found to be effective for measuring methanethiol in aqueous solution. As a result of the screening, TOS-35(Alcaligenes faecalis)demonstrated the highest ability of decomposing methanethiol and two feasibility studies were done in order to test the effectiveness of this bacterium.","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"抄録","attribute_value_mlt":[{"subitem_description":"ﾒﾀﾝﾁｰｵｰﾙは硫黄系有機化合物であり､ppb のｵｰﾀﾞｰでも感知できる強い臭気を有する｡また､毒性を有し水溶性である｡したがって､水溶液中のﾒﾀﾝﾁｵｰﾙを簡便に測定することは非常に重要である｡これまでの研究で､水溶液中のﾒﾀﾝﾁｵｰﾙ濃度を測定するために既存の分析方法を改良して本研究に応用できることを報告している｡本分析法は､5,5ｼﾞﾁｵﾋﾞｽ(2ﾆﾄﾛ安息香酸､DTNB)がﾒﾀﾝﾁｵｰﾙと反応した生成物を 412nm の吸光度で測定するというｴｰﾙﾏﾝ反応に基づくものである｡ﾒﾀﾝﾁｵｰﾙの濃度は､吸光度に比例し､検量線にて容易に定量できた｡そして､微生物分解によるﾒﾀﾝﾁｵｰﾙ濃度の減少量を測定することにより､これらに適応可能かの評価を行い､水溶液中のﾒﾀﾝﾁｵｰﾙを測定することが有効であると判断できた｡本研究では､土壌から分離した菌を有効に利用することにより､脱臭商品や効率的な脱臭装置の開発が期待される｡そこで､分離した TOS-35 などのﾒﾀﾝﾁｵｰﾙ分解菌のﾌｨｰｼﾞﾋﾞﾘﾃｨｽﾀﾃﾞｨを行った結果､脱臭に関して可能性がある事が確認できた｡"}]},"item_10_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎国際大学"}]},"item_10_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11766493"}]},"item_10_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-4094"}]},"item_10_subject_25":{"attribute_name":"Keyword","attribute_value_mlt":[{"subitem_subject":"Ellman reaction, malodorous compounds, feasibility studies","subitem_subject_scheme":"Other"}]},"item_10_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 博"},{"creatorName":"ｻﾄｳ, ﾋﾛｼ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高桑, 進"},{"creatorName":"ﾀｶｸﾜ, ｽｽﾑ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中島, 幸彦"},{"creatorName":"ﾅｶｼﾏ, ﾕｷﾋｺ","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":"2022-05-14"}],"displaytype":"detail","filename":"RN13-015.pdf","filesize":[{"value":"398.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"RN13-015","url":"https://niu.repo.nii.ac.jp/record/852/files/RN13-015.pdf"},"version_id":"4d3a6378-b44a-47e7-85d1-667ebd56e08f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ｴｰﾙﾏﾝ反応"},{"subitem_subject":"悪臭成分"},{"subitem_subject":"ﾌｨｰｼﾞﾋﾞﾘﾃｨｽﾀﾃﾞｨ"}]},"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":"departmental bulletin paper"}]},"item_title":"悪臭成分の分析とﾒﾀﾝﾁｵｰﾙ分解菌の特徴","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"悪臭成分の分析とﾒﾀﾝﾁｵｰﾙ分解菌の特徴"},{"subitem_title":"Analyzing Malodorous Compounds and Characteristics of Methanethiol Decomposing Bacteria","subitem_title_language":"en"}]},"item_type_id":"10","owner":"3","path":["24"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-01"},"publish_date":"2015-04-01","publish_status":"0","recid":"852","relation_version_is_last":true,"title":["悪臭成分の分析とﾒﾀﾝﾁｵｰﾙ分解菌の特徴"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-21T06:15:29.323985+00:00"}
