Results showed that low pH conditions, with a pH below 6.5, significantly enhanced the decay rate of methanogenic microorganisms, leading to irreversible inhibition. Whereas, the acidogenic bacteria were found to be more tolerant to the acidic environment. The biocidal phenomenon was mainly attributed to the proton concentration in the system and was not affected by the presence of phosphate buffer. The impacts of acidic species (C1–C5 VFAs) and the VFA concentration (until 40 mM of un-dissociated VFAs) on the biomass decay were negligibly small comparing to the low pH stress. A modified ADM1 equipped with a lag-phase sub-model could reproduce the deterioration of reactor performance during an acidic failure and resulte in a 37% improvement in the Nash-Sutcliffe efficiency coefficient compared to the calibrated ADM1 model.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第231号"}]},"item_10006_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1334","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ソン, ム"}]}]},"item_10006_version_type_18":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"孙, 梦","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"1333","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":"2023-05-27"}],"displaytype":"detail","filename":"(KKDE1231SM)甲第231号_ソン　ム.pdf","filesize":[{"value":"8.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"(KKDE1231SM)甲第231号_ソン　ム","objectType":"fulltext","url":"https://kitakyu.repo.nii.ac.jp/record/1099/files/(KKDE1231SM)甲第231号_ソン　ム.pdf"},"version_id":"51a67327-a62e-4346-9682-66a49bce982a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Acidic failure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ADM1","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Anaerobic digestion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Archaea decay","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Biocidal inhibition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lag phase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Methanogen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PMA-qPCR","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"VFA inhibition","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Accelerated methanogens’ decay in the acidic environment and its mathematical modelling","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Accelerated methanogens’ decay in the acidic environment and its mathematical modelling","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"14","path":["10"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-05-27"},"publish_date":"2023-05-27","publish_status":"0","recid":"1099","relation_version_is_last":true,"title":["Accelerated methanogens’ decay in the acidic environment and its mathematical modelling"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-13T06:54:23.745322+00:00"}
