In substrate utilization tests, the culture was able to oxidize naphthalene, 2-methylnaphthalene, 1- and 2-naphthoic acids, phenylacetic acid, benzoic acid, cyclohexanecarboxylic acid, and cyclohex-1-ene-carboxylic acid with sulfate as the electron acceptor. Neither hydroxylated 1- or 2-naphthoic acid derivatives and 1- or 2-naphthol nor the monoaromatic compounds ortho-phthalic acid, 2-carboxy-1-phenylacetic acid, and salicylic acid were utilized by the culture within 100 days. 2-Naphthoic acid accumulated in all naphthalene-grown cultures. Reduced 2-naphthoic acid derivatives could be identified by comparison of mass spectra and coelution with commercial reference compounds such as 1,2,3,4-tetrahydro-2-naphthoic acid and chemically synthesized decahydro-2- naphthoic acid. 5,6,7,8-Tetrahydro-2-naphthoic acid and octahydro-2-naphthoic acid were tentatively identified by their mass spectra. The metabolites identified suggest a stepwise reduction of the aromatic ring system before ring cleavage. In degradation experiments with [1-13C]naphthalene or deuterated D8-naphthalene, all metabolites mentioned derived from the introduced labeled naphthalene. When a [13C]bicarbonate-buffered growth medium was used in conjunction with unlabeled naphthalene, 13C incorporation into the carboxylic group of 2-naphthoic acid was shown, indicating that activation of naphthalene by carboxylation was the initial degradation step. No ring fission products were identified.</dcterms:abstract> <dc:creator>Annweiler, Eva</dc:creator> <dc:rights>terms-of-use</dc:rights> <dcterms:issued>2000</dcterms:issued> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:language>eng</dc:language> <dspace:hasBitstream rdf:resource=""/> <dc:creator>Schink, Bernhard</dc:creator> <dcterms:rights rdf:resource=""/> <dc:date rdf:datatype="">2011-03-24T17:35:49Z</dc:date> <bibo:uri rdf:resource=""/> <dc:contributor>Michaelis, Walter</dc:contributor> <dc:format>application/pdf</dc:format> <dc:contributor>Meckenstock, Rainer U.</dc:contributor> <dc:contributor>Schink, Bernhard</dc:contributor> <dcterms:isPartOf rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:bibliographicCitation>First publ. in: Applied and Environmental Microbiology 66 (2000), 7, pp. 2743-2747</dcterms:bibliographicCitation> <dc:creator>Michaelis, Walter</dc:creator> <dc:contributor>Annweiler, Eva</dc:contributor> <dc:creator>Richnow, Hans H.</dc:creator> <dcterms:title>Anaerobic Naphthalene Degradation by a Sulfate-Reducing Enrichment Culture</dcterms:title> <dc:creator>Meckenstock, Rainer U.</dc:creator> <dc:contributor>Richnow, Hans H.</dc:contributor> <dspace:isPartOfCollection rdf:resource=""/> </rdf:Description> </rdf:RDF>
