The G + C content of the DNA was 34.9 + 1.0 mol %. The new isolate fermented triethanolamine to acetate and ammonia. In cell-free extracts, a triethanolaminedegrading enzyme activity was detected that formed acetaldehyde as reaction product. Triethanolamine cleavage was stimulated 30-fold by added adenosylcobalamin (coenzyme B12) and inhibited by cyanocobalamin or hydroxocobalamin. Ethanolamine ammonia lyase, cetaldehyde:acceptor oxidoreductase, phosphate acetyltransferase, acetate kinase, and carbon monoxide dehydrogenase were measured in cell-free extracts of this strain. Our results establish that triethanolamine is degraded by a orrinoid-dependent shifting of the terminal hydroxyl group to the subterminal carbon atom, analogous to a diol dehydratase reaction, to form an unstable intermediate that releases acetaldehyde. No anaerobic degradation of triethylamine was observed in similar enrichment assays.</dcterms:abstract> <dc:creator>Wondrak, Christine</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/8492"/> <dcterms:issued>1994</dcterms:issued> <dcterms:bibliographicCitation>First publ. in: Archives of Microbiology 162 (1994), 1-2, pp. 103-107</dcterms:bibliographicCitation> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:44:07Z</dc:date> <dc:contributor>Schink, Bernhard</dc:contributor> <dc:contributor>Frings, Joachim</dc:contributor> <dc:creator>Schink, Bernhard</dc:creator> <dcterms:title>Fermentative degradation of triethanolamine by a homoacetogenic bacterium</dcterms:title> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:44:07Z</dcterms:available> <dc:creator>Frings, Joachim</dc:creator> <dc:language>eng</dc:language> <dc:contributor>Wondrak, Christine</dc:contributor> </rdf:Description> </rdf:RDF>
