The current systematics of the genus Rhodococcus is unclear, partly because many members were originally included before the application of a polyphasic taxonomic approach, central to which is the acquisition of 16S rRNA sequence data. This has resulted in the reclassification and description of many new species. Hence, the literature is replete with new species names that have not been brought...

Bacteria belonging to the Gram-positive actinomycete species, Rhodococcus erythropolis, are diverse not only in terms of metabolic potentials but the plasmids they encode. It was shown previously that the R. erythropolis AN12 genome harbors a 6.3kb cryptic plasmid called pAN12, which is a member of the pIJ101 family of plasmids. Here we show that pAN12 is conjugatively mobilizable into other rh...

Cesium-accumulating bacteria, strains CS98 and CS402, were isolated from soil by a radioactive autoradiographic method using 137Cs. These strains displayed the rod-coccus growth cycle and contained mesodiaminopimelic acid, mycolic acids, and tuberculostearic acids. The major menaquinone of CS98 was MK-8(H2). On the basis of these characteristics, strain CS98 was identified as Rhodococcus erythr...

BACKGROUND Putrescine oxidase (EC 1.4.3.10) is of interest for the microbial production unsubstituted platform nitrogen (N-)heterocycles, because it only requires inexpensive oxygen as co-substrate. from Rhodococcus erythropolis (Re-PuO) was shown previously to catalyze oxidation cadaverine; however, there little information in literature about robustness this enzyme biotechnological applicatio...

Bile acids are highly abundant steroids with important functions in vertebrate digestion. Their catabolism by bacteria is an important component of the carbon cycle, contributes to gut ecology, and has potential commercial applications. We found that Rhodococcus jostii RHA1 grows well on cholate, as well as on its conjugates, taurocholate and glycocholate. The transcriptome of RHA1 growing on c...
