(Submitter supplied) The cadmium-resistant Cupriavidus sp. E324 strain has been previously shown to have a high potential for use in cadmium (Cd) remediation, due to its high capacity for cadmium bioaccumulation. According to the comparative genomic analysis, the E324 strain was most closely related to C. nantongensis X1 T , indicating that the E324 strain should be re-identified as C. nantongensis. To unravel the Cd tolerance mechanisms of C. more...

(Submitter supplied) Cupriavidus metallidurans CH34 is a well-studied metal-resistant β-proteobacterium and contains a battery of genes involved in the resistance and processing of numerous metals. Here, we performed a directed evolution experiment to obtain derivatives adapted to grow in the presence of zinc at concentrations above the minimal inhibitory concentration for the parental strain. Genetic characterization of one derivative, CH34ZnR, which was also more resistant to cadmium, revealed seven mutations, including inactivation of glpR coding for a DeoR-type transcriptional repressor by insertion of IS1088. more...

(Submitter supplied) These data belong to a metabolic engineering project that introduces the reductive glycine pathway for formate assimilation in Cupriavidus necator. As part of this project we performed short-term evolution of the bacterium Cupriavidus necator H16 to grow on glycine as sole carbon and energy source. Some mutations in a putiative glycine transporting systems facilitated growth, and we performed transcriptomics on the evolved strain growing on glycine. more...

(Submitter supplied) Background: The uncontrolled and widespread use of (nano)silver compounds has led to the increased release of these compounds into the environment, raising concerns about their negative impact on ecosystems. Concomitantly, silver resistance determinants are widely spread among environmental and clinically relevant bacteria although the underlying mechanisms are not yet fully understood. Results: In this study, we show that Cupriavidus metallidurans is able to adapt to toxic silver concentrations and explicate the genetic circuit responsible for this adaptation. more...

(Submitter supplied) Bacteria can respond to adverse environments by increasing their genomic variability and subsequently facilitating adaptive evolution. To demonstrate this, the contribution of Insertion Sequence (IS) elements to the genetic adaptation of Cupriavidus metallidurans AE126 to toxic zinc concentrations was determined. This derivative of type strain CH34, devoid of its main zinc resistance determinant, is still able to increase its zinc resistance level. more...

(Submitter supplied) Various environmental bacteria were adapted to the presence of toxic and recalcitrant organic solvents. Cupriavidus metallidurans CH34, a β-proteobacterium that was found in industrial environments is known as a bacterial model to study heavy metal resistance. Interestingly, genome screening of CH34 also reveals the existence of genes involved in the degradation of recalcitrant organic solvents, such acetone and aromatic compounds. more...

(Submitter supplied) Different Cupriavidus metallidurans strains isolated from metal-contaminated and other anthropogenic environments were genotypically and phenotypically compared with C. metallidurans type strain CH34. The latter is well-studied for its resistance to a wide range of metals, which is carried for a substantial part by its two megaplasmids pMOL28 and pMOL30. Comparative genomic hybridization (CGH) indicated that the extensive arsenal of determinants involved in metal resistance was well conserved among the different C. more...

(Submitter supplied) The physiological and transcriptomic response of the metal resistant bacterium Cupriavidus metallidurans strain CH34 in response to stable (non-radioactive) strontium ions (Sr) was investigated. C. metallidurans CH34 could survive and proliferate in the presence of relatively high concentrations of SrCl2 (D10 is 70mM, MIC is 120 mM). Precipitation of Sr as strontium carbonate was observed in the culture during aerobic growth of CH34 in the presence of 60 mM SrCl2. more...
