The true nature of this role has been underestimated for a long time, because only microorganisms inhabiting saline wetland sediments, or those symbiotically living in aquatic invertebrates, were considered responsible until very recently. Although it is still unknown whether the majority of planktonic/benthic invertebrates possess endogenous cellulase, it is necessary to comprehensively investigate the distribution of cellulase activities in saline wetland invertebrates before any further studies. In the present study, we found that cellulase activities were widely distributed in invertebrates inhabiting a mangrove area of East Java, Indonesia, including Mollusca, Arthropoda and Cnidaria species that were not reported to have cellulase activity in previous studies. Moreover, cellulase activities were also detected in fallen leaves and sediments along the coastline, or below the water surface in Pang-Pang Bay of East Java, suggesting the involvement of small organisms such as meiobenthic invertebrates. To date, organic matter in sediments has been empirically classified into easy-to-decompose organic matter (EDOM) such as protein and starch, and non- degradable organic matter (NDOM) such as cellulose and lignin. However, from the viewpoint of food chain- related research, cellulose undergoes biodegradation together with hemicellulose. We thus propose to classify cellulose as quasi-hard-to-degrade organic matter (qHDOM). To understand the role played by invertebrates in the decomposition of qHDOM in wetlands, we therefore updated the information on aquatic invertebrates’ cellulase through a review of previous studies.\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20643/00001511","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"大阪市立自然史博物館"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0078-6675","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"劉, 文"},{"creatorName":"リュウ, ウェン","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4262","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ナフィシャ, アユ・ラナ"},{"creatorName":"ナフィシャ, アユ・ラナ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4263","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小池, 一彦"},{"creatorName":"コイケ, カズヒコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4264","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松岡, 數充"},{"creatorName":"マツオカ, カズミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3808","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"LIU, Wen","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4265","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAFISYAH, Ayu-Lana","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4266","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KOIKE, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4267","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MATSUOKA, Kazumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3810","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":"2021-04-01"}],"displaytype":"detail","filename":"02_欧文 劉文_15-28.pdf","filesize":[{"value":"17.2 MB"}],"format":"application/pdf","licensetype":"license_9","mimetype":"application/pdf","url":{"label":"インドネシア・ジャワ島東部のマングローブ湿地帯での予備的調査結果に基づくセルラーゼ活性の再評価","url":"https://omnh.repo.nii.ac.jp/record/1545/files/02_欧文 劉文_15-28.pdf"},"version_id":"84230765-01aa-4842-b33b-0edc6f8c23ff"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CMCase plate assay","subitem_subject_scheme":"Other"},{"subitem_subject":"benthic invertebrates","subitem_subject_scheme":"Other"},{"subitem_subject":"cellulose","subitem_subject_scheme":"Other"},{"subitem_subject":"cellulase","subitem_subject_scheme":"Other"},{"subitem_subject":"Pang-Pang Bay","subitem_subject_scheme":"Other"},{"subitem_subject":"Indonesia","subitem_subject_scheme":"Other"},{"subitem_subject":"CMCase plate assay","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"benthic invertebrates","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cellulose","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cellulase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pang-Pang Bay","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Indonesia","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"インドネシア・ジャワ島東部のマングローブ湿地帯での予備的調査結果に基づくセルラーゼ活性の再評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"インドネシア・ジャワ島東部のマングローブ湿地帯での予備的調査結果に基づくセルラーゼ活性の再評価"},{"subitem_title":"Reappraisal of cellulase activities in mangrove wetlands resulting from preliminary investigations in East Java, Indonesia","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"8","path":["272"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-01"},"publish_date":"2021-04-01","publish_status":"0","recid":"1545","relation_version_is_last":true,"title":["インドネシア・ジャワ島東部のマングローブ湿地帯での予備的調査結果に基づくセルラーゼ活性の再評価"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2023-05-15T13:10:07.578442+00:00"}
