Project description:Rhodococcus sp.strain BUPNP1 can utilize the priority environmental pollutant 4-nitrophenol (4-NP) as its sole source of carbon and energy. In this study, genome and transcriptome sequencing were used to gain mechanistic insights into 4-NP degradation. The draft BUPNP1 genome is 5.56 Mbp and encodes 4,963 proteins, which are significantly enriched in hypothetical proteins compared to other Rhodococcus sp. A novel 4-NP catabolic 43 gene cluster "nph" was identified that encodes all the genes required for the conversion of 4-NP into acetyl-CoA and succinate, via 4-nitrocatechol. The cluster also encodes pathways for the catabolism of other diverse aromatic compounds. Comparisons between BUPN1 growing on either 4-NP or glucose resulted in significant changes in the expression of many nph cluster genes, and, during 4-NP growth, a loss of lipid inclusions. Moreover, fatty acid degradation/synthesis genes were found within the nph cluster, suggesting fatty acids may be concurrently catabolised with 4-NP. A holistic model for the action of the nph gene cluster is proposed which incorporates genetic architecture, uptake and metabolism of aromatic compounds, enzymatic activities and transcriptional regulation. The model provides testable hypotheses for further biochemical investigations into the genes of the nph cluster, for potential exploitation in bioremediation.
Project description:This SuperSeries is composed of the following subset Series: GSE5268: Effects of biphenyl on Rhodococcus sp. RHA1 GSE5269: Effects of ethylbenzene on Rhodococcus sp. RHA1 GSE5270: Effects of benzoate on Rhodococcus sp. RHA1 Refer to individual Series
Project description:The draft genome sequences of plant-associated Rhodococcus spp. from Tunisia are reported here. Two Rhodococcus fascians strains were obtained from almond rootstocks, and one Rhodococcus kroppenstedtii strain was obtained from a pistachio tree. The fourth Rhodococcus sp. strain was isolated from an ornamental plant.
Project description:The complete genome sequence of Rhodococcus sp. strain SGAir0479 is presented here. This organism was isolated from an air sample collected in an indoor location in Singapore. The consensus assembly generated one chromosome of 4.86?Mb (G+C content of 69.8%) and one plasmid of 104,493?bp.
Project description:The genus Rhodococcus has proved to be a promising option for the cleanup of polluted sites and application of a microbial biocatalyst. Rhodococcus sp. strain R04, isolated from oil-contaminated soil, can biodegrade polychlorinated biphenyls. Here we report the draft genome sequence of Rhodococcus sp. strain R04, which could be used to predict genes for xenobiotic biodegradation and provide important insights into the applications of this strain.
Project description:Rhodococcus sp. B7740 was isolated from Arctic seawater and selected for its capacity to synthesize carotenoids. Here, we report the complete genome sequence of Rhodococcus sp. B7740 to provide the genetic basis for a better understanding of its carotenoid-accumulating capabilities, and we describe the major features of the genome.
Project description:The draft genome sequence of subantarctic Rhodococcus sp. strain 1139 is reported here. The genome size is 7.04 Mb with high G+C content (62.3%) and it contains a large number of genes involved in lipid synthesis. This lipid synthesis system is characteristic of oleaginous Actinobacteria, which are of interest for biofuel production.
Project description:Rhodococcus sp. WB1 is a polychlorinated biphenyl degrader which was isolated from contaminated soil in Zhejiang, China. Here, we present the complete genome sequence. The analysis of this genome indicated that a biphenyl-degrading gene cluster and several xenobiotic metabolism pathways are harbored.
