The critical temperatures for the survival of wet cysts ranged from 40 oC (3-hr exposure) to 45 oC (10-min exposure), and those of the dried cysts ranged from 80 oC (3-hr exposure) to 100 oC (30-min exposure). Frozen (-30 oC, 3 hr) and remelted wet cysts also survived. Ca2+-induced resting cysts excysted when the external Ca2+ was removed. However, the excystment-inducing effect by Ca2+ removal was canceled by the addition of cations such as Na+, K+, and Mg2+ in the surrounding medium. When the mature cysts transformed in a diluted buffer without any other salts were temporally exposed to Ca2+ and subsequently resuspended in the buffer without Ca2+, excystment was induced in a majority of cysts. The addition of chlorophyll-derived molecules in the surrounding medium induced excystment, but suppressed encystment. This suggests that the excystment-inducing and encystment-suppressing activities of cereal infusion are attributed to water-soluble porphyrins derived from chlorophyll. The encystment was induced when the vegetative cells were suspended at a high density, and the substitution of non-living particles such as polystyrene latex particles (PLP) for the living cells also showed an encystment-inducing effect. The result suggests that mechanical cell-to-cell contact induces encystment.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Research Center for Protozoan Diseases","subitem_publisher_language":"en"}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"National Research Center for Protozoan Diseases","subitem_rights_language":"en"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10824856","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09174427","subitem_source_identifier_type":"PISSN"}]},"item_2_subject_21":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"649","subitem_subject_scheme":"NDC"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","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":"Maeda, Hajime","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akematsu, Takahiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukui, Risa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuoka, Tatsuomi","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":"2018-01-30"}],"displaytype":"detail","filename":"Prot.Vol15-(2).pdf","filesize":[{"value":"122.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Prot.Vol15-(2).pdf","url":"https://obihiro.repo.nii.ac.jp/record/1501/files/Prot.Vol15-(2).pdf"},"version_id":"17e2377e-4611-462b-aadd-b41377e02abf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Colpoda","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"encystment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"excystment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"resistance to temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ca2+","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"porphyrins","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Studies on the resting cyst of ciliated protozoan Colpoda cucullus: resistance to temperature and additional inducing factors for en-or excystment","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Studies on the resting cyst of ciliated protozoan Colpoda cucullus: resistance to temperature and additional inducing factors for en-or excystment","subitem_title_language":"en"}]},"item_type_id":"2","owner":"12","path":["28"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2006-12-20"},"publish_date":"2006-12-20","publish_status":"0","recid":"1501","relation_version_is_last":true,"title":["Studies on the resting cyst of ciliated protozoan Colpoda cucullus: resistance to temperature and additional inducing factors for en-or excystment"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2023-08-29T09:14:00.305635+00:00"}
