“…A recent study of sphingomonad diversity on a range of environmental niches reported that members of the genus Sphingomicrobium are particularly strongly associated with marine habitats (Huang et al 2017). Whereas there is no evidence for hydrocarbon utilization by most of the seawater-derived strains, marine sediments have yielded isolates that degrade PAHs (Gilewicz et al 1997;Johnson and Hill 2003) or PCBs (Begonja Kolar et al 2007).…”

The bacterial order Sphingomonadales includes many Sphingomonadaceae and Erythrobacteraceae isolates that have the ability to degrade a wide range of hydrocarbons. Hydrocarbon-degrading members of the Sphingomonadaceae (mainly belonging to the genera Sphingomonas, Sphingobium, Novosphingobium, and Sphingopyxis) are common Gram-negative aerobic organisms that have been isolated from a wide variety of environments, including

“…A wide range of chemicals, in particular aromatics and hydrocarbons, can be degraded by Rhodococcus. Natural isolates have been found to degrade polychlorinated biphenyls (PCBs), a common pollutant from industrial oils (Begonja Kolar et al, 2007).…”

“…An example is ethyl tert-butyl ether, a common pollutant from petrol (Chauvaux et al, 2001). Like R. erythropolis, some strains of R. ruber can degrade PCBs (Begonja Kolar et al, 2007). Most interestingly, R. ruber can metabolise polyethylene, one of the most widespread and most recalcitrant plastic pollutants known (Gilan et al, 2004), which could lead to the bioremediation of landfill.…”

The adaptation of Rhodocccus erythropolis SQ1 to energy and carbon starvation was investigated in terms of both the capacity to survive starvation and the contribution of a nutrient-induced stationary phase to cross-protection to other types of environmental stress. It was found that R. erythropolis SQ1 survives for at least 43 days in LB and distilled water, and 65 days in chemically defined medium (CDM) containing high (1%) or low (0.1%) glucose. Furthermore, early stationary-phase R. erythropolis SQ1 grown in CDM 0.1% exhibited enhanced resistance to heat and oxidative stress compared with exponential-phase cells. A second objective of this study was to identify genetic elements involved in starvation/stationary-phase survival. A mutant bank of R. erythropolis SQ1 generated by random transposon insertion mutagenesis was screened; four mutants lost culturability when grown in CDM 1%. No drop in culturability was observed when these mutants were grown in CDM 0.1%. The DNA flanking transposon insertion could be recovered from three mutants. Transposon insertions were found in uvrB (UvrB, part of the DNA excision repair mechanism), between a putative guaB gene and another guaB-like gene, and between a gene encoding a putative phosphoglycerate mutase and putative thioredoxin/cytochrome c biogenesis genes. This represents a first study of the starvation/stationary-phase survival response of Rhodococcus, an organism of immense significance in environmental bioremediation and a number of industrial processes.
