D1, which can utilize 1,4-dioxane as the sole carbon source. Strain D1 was entrapped in a polyethylene glycol gel carrier to stably maintain it in a bioreactor, and continuous feeding tests were performed to treat model industrial wastewater containing 1,4-dioxane. 1,4-Dioxane removal activity rapidly increased soon after the start of feeding of influent with 400 mg/L 1,4-dioxane, and the volumetric removal rate reached 0.67 kg dioxane/m(3)/d on day 36 by a stepwise increase in loading. The start-up period of the 1,4-dioxane treatment reactor was approximately 1 month, and stable removal performance was subsequently achieved for more than 1 month. The average 1,4-dioxane effluent concentration and 1,4-dioxane removal efficiency were 3.6 mg/L and 99%, respectively, during stable operation. Further 1,4-dioxane degradation activity of the of the gel carrier was characterized in batch experiments with respect to temperature. The optimum temperature for 1,4-dioxane treatment was 31.7°C, and significant removal was observed at a temperature as low as 6.9°C. The apparent activation energy for 1,4-dioxane degradation was estimated to be 47.3 kJ/mol. This is the first report of the development of a 1,4-dioxane biological treatment system using gel entrapment technology."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1581135652477895298","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000330752508"}],"foaf:name":[{"@value":"Yuya Kimura"}]},{"@id":"https://cir.nii.ac.jp/crid/1420564276163115520","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"40543939"},{"@type":"NRID","@value":"1000040543939"},{"@type":"NRID","@value":"9000006431542"},{"@type":"NRID","@value":"9000006203836"},{"@type":"NRID","@value":"9000304618032"},{"@type":"NRID","@value":"9000000626803"},{"@type":"NRID","@value":"9000367822005"},{"@type":"NRID","@value":"9000415073072"},{"@type":"NRID","@value":"9000330752506"},{"@type":"NRID","@value":"9000314071736"},{"@type":"NRID","@value":"9000288824253"},{"@type":"NRID","@value":"9000401530216"},{"@type":"NRID","@value":"9000045430129"},{"@type":"NRID","@value":"9000383840039"},{"@type":"NRID","@value":"9000401957177"},{"@type":"NRID","@value":"9000414374733"},{"@type":"NRID","@value":"9000345265647"},{"@type":"NRID","@value":"9000021574721"},{"@type":"NRID","@value":"9000014257145"},{"@type":"NRID","@value":"9000383840177"},{"@type":"NRID","@value":"9000410659351"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/40543939"}],"foaf:name":[{"@value":"Kazuichi Isaka"}]},{"@id":"https://cir.nii.ac.jp/crid/1581135652477895296","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000330752507"}],"foaf:name":[{"@value":"Makiko Udagawa"}]}],"publication":{"publicationIdentifier":[{"@type":"NDL_BIB_ID","@value":"000000160357"},{"@type":"ISSN","@value":"13891723"},{"@type":"PISSN","@value":"13891723"},{"@type":"NCID","@value":"AA11307678"}],"prism:publicationName":[{"@value":"Journal of bioscience and bioengineering"}],"dc:publisher":[{"@value":"Suita : Society for Biotechnology"}],"prism:publicationDate":"2016-02","prism:volume":"121","prism:number":"2","prism:startingPage":"203","prism:endingPage":"208"},"reviewed":"false","url":[{"@id":"http://id.ndl.go.jp/bib/027124204"},{"@id":"https://ndlsearch.ndl.go.jp/books/R000000004-I027124204"},{"@id":"https://api.elsevier.com/content/article/PII:S1389172315002364?httpAccept=text/plain"},{"@id":"https://api.elsevier.com/content/article/PII:S1389172315002364?httpAccept=text/xml"}],"foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Wastewater%20treatment","dc:title":"Wastewater treatment"},{"@id":"https://cir.nii.ac.jp/all?q=1,4-Dioxane","dc:title":"1,4-Dioxane"},{"@id":"https://cir.nii.ac.jp/all?q=Afipia%20sp","dc:title":"Afipia sp"},{"@id":"https://cir.nii.ac.jp/all?q=Gel","dc:title":"Gel"},{"@id":"https://cir.nii.ac.jp/all?q=Immobilization","dc:title":"Immobilization"},{"@id":"https://cir.nii.ac.jp/all?q=Biodegradation","dc:title":"Biodegradation"},{"@id":"https://cir.nii.ac.jp/all?q=Bioreactor","dc:title":"Bioreactor"},{"@id":"https://cir.nii.ac.jp/all?q=Immobilized%20cells","dc:title":"Immobilized cells"},{"@id":"https://cir.nii.ac.jp/all?q=Moving%20bed%20bioreactors","dc:title":"Moving bed bioreactors"},{"@id":"https://cir.nii.ac.jp/all?q=Enzyme%20activity","dc:title":"Enzyme activity"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360003443886282752","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Immobilization of nitrifying bacteria by polyethylene glycol prepolymer"}]},{"@id":"https://cir.nii.ac.jp/crid/1360011145784337536","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Evaluation of the biodegradation potential of 1,4-dioxane in river, soil and activated sludge samples"}]},{"@id":"https://cir.nii.ac.jp/crid/1360292619146138624","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Biodegradation of Ether Pollutants by\n            <i>Pseudonocardia</i>\n            sp.
