Monocyclic aromatic hydrocarbon degradation by Rhodococcus sp. strain DK17.
Rhodococcus sp. strain DK17 was isolated from soil and analyzed for the ability to grow on o-xylene as the sole carbon and energy source. Although DK17 cannot grow on m- and p-xylene, it is capable of growth on benzene, phenol, toluene, ethylbenzene, isopropylbenzene, and other alkylbenzene isomers. One UV-generated mutant strain, DK176, simultaneously lost the ability to grow on o-xylene, ethy...
متن کاملIdentification of a novel dioxygenase involved in metabolism of o-xylene, toluene, and ethylbenzene by Rhodococcus sp. strain DK17.
Rhodococcus sp. strain DK17 is able to grow on o-xylene, benzene, toluene, and ethylbenzene. DK17 harbors at least two megaplasmids, and the genes encoding the initial steps in alkylbenzene metabolism are present on the 330-kb pDK2. The genes encoding alkylbenzene degradation were cloned in a cosmid clone and sequenced completely to reveal 35 open reading frames (ORFs). Among the ORFs, we ident...
متن کاملDifferential degradation of bicyclics with aromatic and alicyclic rings by Rhodococcus sp. strain DK17.
The metabolically versatile Rhodococcus sp. strain DK17 is able to grow on tetralin and indan but cannot use their respective desaturated counterparts, 1,2-dihydronaphthalene and indene, as sole carbon and energy sources. Metabolite analyses by gas chromatography-mass spectrometry and nuclear magnetic resonance spectrometry clearly show that (i) the meta-cleavage dioxygenase mutant strain DK180...
متن کاملBenzoate catabolite repression of the phthalate degradation pathway in Rhodococcus sp. strain DK17.
Rhodococcus sp. strain DK17 exhibits a catabolite repression-like response when provided simultaneously with benzoate and phthalate as carbon and energy sources. Benzoate in the medium is depleted to detection limits before the utilization of phthalate begins. The transcription of the genes encoding benzoate and phthalate dioxygenase paralleled the substrate utilization profile. Two mutant stra...
متن کاملGenome Sequence of Rhodococcus sp. Strain RD6.2 DSM 46800, a Methanesulfonate-Degrading Strain
The complete genome sequence of a methanesulfonate-degrading strain, Rhodococcus sp. strain RD6.2 DSM 46800, which was isolated from a brackish marsh sediment sample, is described here. This is the first reported genome of a nonproteobacterial strain using methanesulfonate (MSA) as a sole source of carbon and energy, which does not possess the conventional MSA-monooxygenase (MSAMO).
