In such a gradient system, the fluxes of methane and oxygen are controlled by diffusion and consumption rates, and the rate-limiting substrate is maintained at a minimum concentration at the layer of consumption. Opposing gradients of methane and oxygen were mimicked in a specific cultivation set-up in which growth of methanotrophic bacteria occurred as a sharp band at either c. 5 or 20mm below the air-exposed end. Two new strains of methanotrophic bacteria were isolated with this system. One isolate, strain LC 1, belonged to the Methylomonas genus (type I methantroph) and contained soluble methane mono-oxygenase. Another isolate, strain LC 2, was related to the Methylobacter group (type I methantroph), as determined by 16S rRNA gene and pmoA sequence similarities. However, the partial pmoA sequence was only 86% related to cultured Methylobacter species. This strain accumulated significant amounts of formaldehyde in conventional cultivation with methane and oxygen, which may explain why it is preferentially enriched in a gradient cultivation system.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: FEMS Microbiology Ecology 56 (2006), 3, pp. 331-344</dcterms:bibliographicCitation> <dc:creator>Schink, Bernhard</dc:creator> <dc:language>eng</dc:language> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:39:49Z</dc:date> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/8085"/> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:creator>Bussmann, Ingeborg</dc:creator> <dc:contributor>Schink, Bernhard</dc:contributor> <dcterms:issued>2006</dcterms:issued> <dc:contributor>Bussmann, Ingeborg</dc:contributor> </rdf:Description> </rdf:RDF>
