Project description:Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a persistent nitramine explosive with long-lasting properties. Rhodococcus sp. strain DN22 has been discovered as one of the microorganisms capable of RDX degradation. Despite respectable studies on Rhodococcus sp. strain DN22, the proteins participating in RDX degradation (Oxidoreductase and Cytochrome P450) in the strain remain to be fragments. In this study, complete genome of Rhodococcus sp. strain DN22 was sequenced and analyzed, and the entire sequences of the two genes encoding Oxidoreductase and Cytochrome P450 in Rhodococcus sp. strain DN22 were predicted, which were validated through proteomic data. Besides, despite the identification of certain chemical substances as proposed characterized degradation intermediates of RDX, few studies have investigated the physiological changes and metabolic pathways occurring within Rhodococcus sp. cells when treated with RDX, particularly through the use of mass spectrometry-based omics. Hence, proteomics and metabolomics of Rhodococcus sp. strain DN22 were performed and analyzed with the presence or absence of RDX in the medium. A total of 3186 protein groups were identified and quantified between the two groups, with 117 proteins being significantly differentially expressed proteins. A total of 1056 metabolites were identified after merging positive and negative ion modes, among which 131 metabolites were significantly differential. Through the combined analysis of differential proteomics and metabolomics, several KEGG pathways, including two-component system, ABC transporters, alanine, aspartate and glutamate metabolism, arginine biosynthesis, purine metabolism, nitrogen metabolism, and phosphotransferase system (PTS) were found to be significantly enriched. We expect that our investigation will expand the acquaintance of Rhodococcus sp. strain DN22, and the knowledge of microbial degradation.

Project description:Background: The high number of heavy metal resistance genes in the soil bacterium Cupriavidus metallidurans CH34 makes it an interesting model organism to study microbial responses to heavy metals. Results: In this study the transcriptional response of this bacterium was measured after challenging it to a wide range of sub-lethal concentrations of various essential or toxic metals. Considering the global transcriptional responses for each challenge as well as by identifying the overlap in upregulated genes between different metal responses, the sixteen metals could be clustered in three different groups. Additionally, next to the assessment of the transcriptional response of already known metal resistance genes, new metal response gene clusters were identified. The majority of the metal response loci showed similar expression profiles when cells were exposed to different metals, suggesting complex cross-talk at transcriptional level between the different metal responses. The highly redundant nature of these metal resistant regions – illustrated by the large number of paralogous genes – combined with the phylogenetic distribution of these metal response regions within evolutionary related and other metal resistant bacteria, provides important insights on the recent evolution of this naturally soil dwelling bacterium towards a highly metal-resistant strain found in harsh and anthropogenic environments. Conclusions: The metal-resistant soil bacterium Cupriavidus metallidurans CH34 displays myriads of gene expression patterns when exposed to a wide range of heavy metals at non-lethal concentrations. The interplay between the different gene expression clusters points towards a complex cross-regulated regulatory network governing heavy metal resistance in C. metallidurans CH34. Keywords: Cupriavidus metallidurans CH34, transcriptional regulation, heavy metal resistance

Project description:We analyzed the transcriptional response of the actinomycete Rhodococcus aetherivorans I24 to biphenyl and polychlorinated biphenyls (PCBs). This species has not been extensively exposed to PCBs, as it was first isolated from a toluene contaminated aquifer, rather than a site contaminated with polychlorinated hydrocarbons. Using a microarray targeting 3524 genes, we assessed gene expression in minimal medium supplemented with various substrates (e.g. PCBs) and in both PCB-contaminated and non-contaminated sediment slurries. Relative to the reference condition (minimal medium supplemented with glucose), 408 genes were up-regulated in the various treatments. In medium and in sediment, PCBs elicited the up-regulation of a common set of 100 genes, including chaperones (groEL), a superoxide dismutase (sodA), alkyl hydroperoxide reductase protein C (ahpC), and a catalase/peroxidase (katG). Analysis of the R. aetherivorans I24 genome sequence identified orthologs of many of the genes in the canonical biphenyl pathway, but very few of these genes were up-regulated in response to PCBs or biphenyl. This study is one of the first which utilizes microarrays to assess the transcriptional response of a soil bacterium to a pollutant under conditions which more closely resemble the natural environment. Our results indicate that the transcriptional response of R. aetherivorans I24 to PCBs, in both medium and sediment, is primarily directed towards reducing oxidative stress, rather than catabolism. In addition, the identification of numerous genes expressed in contaminated soil specifically may have implications for the development of biosensors. Finally, comparative genomic and transcriptomic analyses suggest that the mere presence of orthologs of the required enzymes may not be sufficient to confer a vigorous biphenyl/PCB metabolism.

Project description:The marine bacterium Rhodococcus erythropolis PR4 was demonstrated to be able for assimilation/biodegradation of hydrocarbons. Not just the chromosome but two large plasmids provide versatile enzyme sets involved in many metabolic pathways. In order to identify the key elements involved in biodegradation of the model compound, hexadecane, and diesel oil, we performed whole transcriptome analysis on cells grown in the presence of n-hexadecane and diesel oil. Sodium acetate grown cells were used as control. The final goal of the project is a comparative transcriptomic analysis of Rhodococcus erythropolis PR4 cells grown on acetate, on the model compound: hexadecane and the real substrate: diesel oil. Comparative transcriptomics of Rhodococcus erythropolis PR4 grown on n-hexadecane, diesel oil, and sodium acetate.
