13. Degradation of 2,4-dinitrophenol by two Rhodococcus erythropolis strains, HL 24-1 and HL 24-2.
Two Rhodococcus erythropolis strains, HL 24-1 and HL 24-2, were isolated from soil and river water by their abilities to utilize 2,4-dinitrophenol (0.5 mM) as the sole source of nitrogen. Although succinate was supplied as a carbon and energy source during selection, both isolates could utilize 2,4-dinitrophenol also as the sole source of carbon. Both strain

15. Chemical and Physical Characterization of Interfacial-Active Lipids from Rhodococcus erythropolis Grown on n-Alkanes
Lipophilic compounds of the culture suspension containing Rhodococcus erythropolis DSM43215 had surfactant properties when the bacteria were cultivated with n-alkanes as the sole carbon source. Thirteen main components from a dichloromethane-methanol extract of the R. erythropolis cultures were isolated and characterized to specify quantitatively their surfa

16. Diversity of Nitrile Hydratase and Amidase Enzyme Genes in Rhodococcus erythropolis Recovered from Geographically Distinct Habitats
A molecular screening approach was developed in order to amplify the genomic region that codes for the α- and β-subunits of the nitrile hydratase (NHase) enzyme in rhodococci. Specific PCR primers were designed for the NHase genes from a collection of nitrile-degrading actinomycetes, but amplification was successful only with strains identified as Rhodococ

17. Initial hydrogenation during catabolism of picric acid by Rhodococcus erythropolis HL 24-2.
Rhodococcus erythropolis HL 24-2, which was originally isolated as a 2,4-dinitrophenol-degrading bacterium, could also utilize picric acid as a nitrogen source after spontaneous mutation. During growth, the mutant HL PM-1 transiently accumulated an orange-red metabolite, which was identified as a hydride-Meisenheimer complex of picric acid. This complex was

18. Isolation and Characterization of a Rolling-Circle-Type Plasmid from Rhodococcus erythropolis and Application of the Plasmid to Multiple-Recombinant-Protein Expression
We isolated, sequenced, and characterized the cryptic plasmid pRE8424 from Rhodococcus erythropolis DSM8424. Plasmid pRE8424 is a 5,987-bp circular plasmid; it carries six open reading frames and also contains cis-acting elements, specifically a single-stranded origin and a double-stranded origin, which are characteristic of rolling-circle-replication plasmi

19. Selective Desulfurization of Dibenzothiophene by Rhodococcus erythropolis D-1
A dibenzothiophene (DBT)-degrading bacterium, Rhodococcus erythropolis D-1, which utilized DBT as a sole source of sulfur, was isolated from soil. DBT was metabolized to 2-hydroxybiphenyl (2-HBP) by the strain, and 2-HBP was almost stoichiometrically accumulated as the dead-end metabolite of DBT degradation. DBT degradation by this strain was shown to procee

21. Identification and characterization of a transmissible linear plasmid from Rhodococcus erythropolis BD2 that encodes isopropylbenzene and trichloroethene catabolism.
Rhodococcus erythropolis BD2, which is able to utilize isopropylbenzene as a sole carbon and energy source, was shown to contain a conjugative linear plasmid, pBD2. The estimated size of pBD2 is 208 to 212 kb. Linear plasmid-deficient strains had lost both the isopropylbenzene degradation and trichloroethene degradation characteristics, as well as the arseni

22. Multiple genes encoding 2,3-dihydroxybiphenyl 1,2-dioxygenase in the gram-positive polychlorinated biphenyl-degrading bacterium Rhodococcus erythropolis TA421, isolated from a termite ecosystem.
Rhodococcus erythropolis TA421 was isolated from a termite ecosystem and is able to degrade a wide range of polychlorinated biphenyl (PCB) congeners. Genetic and biochemical analyses of the PCB catabolic pathway of this organism revealed that there are four different bphC genes (bphC1, bphC2, bphC3, and bphC4) which encode 2,3-dihydroxybiphenyl dioxygenases.

23. Complete Nucleotide Sequence and Genetic Organization of the 210-Kilobase Linear Plasmid of Rhodococcus erythropolis BD2
The complete nucleotide sequence of the linear plasmid pBD2 from Rhodococcus erythropolis BD2 comprises 210,205 bp. Sequence analyses of pBD2 revealed 212 putative open reading frames (ORFs), 97 of which had an annotatable function. These ORFs could be assigned to six functional groups: plasmid replication and maintenance, transport and metalloresistance, ca

24. Purification, Characterization, and Overexpression of Flavin Reductase Involved in Dibenzothiophene Desulfurization by Rhodococcus erythropolis D-1
The dibenzothiophene (DBT)-desulfurizing bacterium, Rhodococcus erythropolis D-1, removes sulfur from DBT to form 2-hydroxybiphenyl using four enzymes, DszC, DszA, DszB, and flavin reductase. In this study, we purified and characterized the flavin reductase from R. erythropolis D-1 grown in a medium containing DBT as the sole source of sulfur. It is conceiva
