It is thought that the host P. bursaria uses some of photosynthetic products from these algae when sunlight is available. When photosynthesis cannot be performed, P. bursaria preys on bacteria, molds, algae, etc. in the surroundings for an energy source. Interestingly, some of the algae were observed to move from the food vacuole to the cytoplasm, becoming symbionts, within several days after incorporation into the cell. Since P. bursaria is benthic, it should be possible for various kinds of precipitated tiny particles to be taken up into the cell body during predation. In this study, microplastic (MP) beads with a diameter of 1 μm, which is about the same size as the algae, were mixed in the suspension medium of P. bursaria . It was observed that uptake of the beads into the cell body of P. bursaria started within 5 min after mixing, and the beads were observed inside P. bursaria even several days after the addition to the P. bursaria culture suspension. It is highly probable that the MP beads observed in the cell body somehow escaped from the food vacuole and moved into the cytoplasm.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Departmental Bulletin Paper","subitem_description_type":"Other"}]},"item_3_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Full-Length Paper","subitem_description_type":"Other"},{"subitem_description":"By a grant from Research Institute for Integrated Science, Kanagawa University","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"神奈川大学総合理学研究所"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12068302","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-0483","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"Hosoya, Hiroshi"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Suzuki, Kyosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita, Misato"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Hosoya, Natsumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kotani, Susumu"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Hino, Akiya"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-08"}],"displaytype":"detail","filename":"04 Microplastic Beads Incorporated into a Single Cell ： Analyses Using the Green Paramecium, Paramecium bursaria.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"04 Microplastic Beads Incorporated into a Single Cell ： Analyses Using the Green Paramecium, Paramecium bursaria","url":"https://kanagawa-u.repo.nii.ac.jp/record/13568/files/04 Microplastic Beads Incorporated into a Single Cell ： Analyses Using the Green Paramecium, Paramecium bursaria.pdf"},"version_id":"8afd26d7-b119-451e-a9c4-19c85d10d1c8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"protist","subitem_subject_scheme":"Other"},{"subitem_subject":"micro plastic bead","subitem_subject_scheme":"Other"},{"subitem_subject":"cell division","subitem_subject_scheme":"Other"},{"subitem_subject":"benthic","subitem_subject_scheme":"Other"},{"subitem_subject":"ciliate","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Microplastic Beads Incorporated into a Single Cell ： Analyses Using the Green Paramecium, Paramecium bursaria","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Microplastic Beads Incorporated into a Single Cell ： Analyses Using the Green Paramecium, Paramecium bursaria","subitem_title_language":"en"}]},"item_type_id":"3","owner":"10","path":["1311"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-01-08"},"publish_date":"2021-01-08","publish_status":"0","recid":"13568","relation_version_is_last":true,"title":["Microplastic Beads Incorporated into a Single Cell ： Analyses Using the Green Paramecium, Paramecium bursaria"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-06-19T02:08:59.883842+00:00"}
