The results obtained were summarized as follows (1) MR was found to be generally superior to the animal\" yennins in the milk -clotting activity, that is, the rennin activity of MR was approximately four times stronger than that of either HR or NR at 35℃. Optimum temperature for the milk-clotting activity of MR was around 70℃ and the enzymatic activity was fairly observed even at 80℃. However, MR was inferior to HR and NR in the thermostability. The milk-clotting activities of MR, HR and NR increased with decreasing of pH, so far as the activities were measured at various pH's between 6.15 and 6.85. (2) The milk-clotting activity of MR fairly increased by Naz  and remarkably increased by Caz z , whereas Kz  completely inhibited it at the concentration of 75mg%. (3) Relatively strong proteolytic activity was observed in MR. From this fact it is pointed out that further basic experiments on MR are necessary for the practical use of MR As a rennet replacement enzyme.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学農学部紀要 6(2): 101-110(1969)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学農学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0583-0621","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121352","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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":"細野,  明義"}],"nameIdentifiers":[{"nameIdentifier":"34120","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石田,  哲夫"}],"nameIdentifiers":[{"nameIdentifier":"34121","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鴇田,  文三郎"}],"nameIdentifiers":[{"nameIdentifier":"34122","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":"2015-09-25"}],"displaytype":"detail","filename":"Agriculture06-02-02.pdf","filesize":[{"value":"409.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Agriculture06-02-02.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/10870/files/Agriculture06-02-02.pdf"},"version_id":"badfd7ce-c06c-43aa-af84-2e384964d4da"}]},"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":"微生物の生産する一凝乳酵素標品の一般特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"微生物の生産する一凝乳酵素標品の一般特性","subitem_title_language":"ja"},{"subitem_title":"Milk-Clotting and Proteolytic Properties of an Enzyme Prepared from Microbe","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1065"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-03"},"publish_date":"2009-03-03","publish_status":"0","recid":"10870","relation_version_is_last":true,"title":["微生物の生産する一凝乳酵素標品の一般特性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-04T04:07:33.644951+00:00"}
