Response of nitrogen fixation of Chromatium sp. to environmental factors was established by C₂H₂ reduction method. Nitrogen fixation of Chromatium sp. was light-and H₂S-dependent, and the maximum rate, 32.0 nmol C₂H₄/hr/(mg dry cell weight), was obtained. Each of optimum environmental conditions was as follows: light intensity, 1000 lux;pH, 8.5 ; H₂S, 20 mg H₂S-S/l; temperature, 30℃. The bacterium could fix N₂ well at low light intensity and low H2S concentration under inorganic condition. It was suggested that Chromatium sp., having the ability to fix N₂ photoautotrophically even under low light intensity and low H2S concentration, might become an important dominant in the ecosystem and a potential contributor to the nitrogen budget.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.76, pp.1-6; 1995","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"36772","nameIdentifierScheme":"WEKO"}],"names":[{"name":"文, 尚郁"}]},{"nameIdentifiers":[{"nameIdentifier":"36773","nameIdentifierScheme":"WEKO"}],"names":[{"name":"松山, 通郎"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40002770939","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","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":"Moon, Sang-Wook"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuyama, Michiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"suisan76_001.pdf","filesize":[{"value":"502.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan76_001.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9202/files/suisan76_001.pdf"},"version_id":"d9c614db-f2d8-483a-81ca-796e8e0c42e7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Chromatium sp.","subitem_subject_scheme":"Other"},{"subitem_subject":"N_2 fixation","subitem_subject_scheme":"Other"},{"subitem_subject":"C_2H_2 reduction method","subitem_subject_scheme":"Other"},{"subitem_subject":"Environmental factors","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":"Effects of Environmental Factors upon Nitrogen Fixation of Chromatium sp.Isolated from Lake Kaiike","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of Environmental Factors upon Nitrogen Fixation of Chromatium sp.Isolated from Lake Kaiike"}]},"item_type_id":"3","owner":"2","path":["681"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-11-20"},"publish_date":"2012-11-20","publish_status":"0","recid":"9202","relation_version_is_last":true,"title":["Effects of Environmental Factors upon Nitrogen Fixation of Chromatium sp.Isolated from Lake Kaiike"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:51:19.701098+00:00"}
