The organism utilized the enantiomers sequentially. R-SPB was utilized first (specific growth rate [µ] = 0.28 h-1), with transient excretion of an unknown intermediate, which was identified as 4-sulfocatechol (4SC). Utilization of S-SPB was slower (µ = 0.016 h-1) and was initiated only after the first enantiomer was exhausted. Suspensions of cells grown in S-SPB excreted 4SC, so metabolism of the two enantiomers converged at 4SC. The latter was degraded by ortho cleavage via 3-sulfo-cis,cis-muconate. Strain SPB1 grew with 4SC and with 1-(4-sulfophenyl)octane (referred to herein as model LAS) but not with commercial linear alkylbenzenesulfonate (LAS) surfactant, which is subterminally substituted but nontoxic. It would appear that metabolism of the model LAS does not represent metabolism of commercial LAS.</dcterms:abstract> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:14:57Z</dc:date> <dc:contributor>Cook, Alasdair M.</dc:contributor> <dc:creator>Dong, Wenbo</dc:creator> <dc:creator>Cook, Alasdair M.</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9865"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:14:57Z</dcterms:available> <dc:contributor>Groth, Ulrich</dc:contributor> <dc:contributor>Schulz, Saskia</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Applied and Environmental Microbiology 66 (2000), 5, pp. 1905-1910</dcterms:bibliographicCitation> <dc:language>eng</dc:language> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:rights>deposit-license</dc:rights> <dcterms:title>Enantiomeric degradation of 2-(4-sulfophenyl)butyrate via 4-sulfocatechol in Delftia acidovorans SPB1</dcterms:title> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
