Cupriavidus metallidurans

Cadmium cupriavidus metallidurans a highly toxic heavy metal for biological systems. Cupriavidus metallidurans CH34 is a model strain to study heavy metal resistance and bioremediation as it is able to deal with high heavy metal concentrations, cupriavidus metallidurans. The aim of this study was to characterize the response of C.

Scientists from Michigan State University, USA, Kazem Kashefi, assistant professor of microbiology and Adam Brown, associate professor of electronic art and intermedia, found that a bacterium, Cupriavidus metallidurans previously known as Ralstonia metallidurans [ 1 ] that belongs to beta class of proteobacteria can grow on a substantial concentration of toxic gold chloride also known as liquid gold. The bacterium with such potential was first isolated in from the sludge of a metal processing factory located in Belgium [ 3 ]. Its ability to detoxify gold complexes by transforming them into metallic gold was discovered in [ 4 ]. When discovered, the bacterium was initially found to be resistant to cadmium but subsequent studies identified that this strain is multi-metal resistant and has two plasmids pMOL28 and pMOL30 which harbor multiple loci for metal resistance [ 5 ].

This metal-resistant bacterium has not been reported to be pathogenic in humans or animals. A year-old Caucasian man, known to have type 2 diabetes, arteriosclerotic heart disease, dyslipidemia, arterial hypertension, and obesity kg , underwent a radical cystoprostatectomy with ileal duct and ileostomy for a vesical high-grade carcinoma with four pelvic lymph nodes positive for neoplasia. A subtotal pancreatectomy and splenectomy were performed simultaneously for a pancreatic neuroendocrine tumor. In each instance, the patient was treated with antimicrobial agents and drainage. Ten weeks after the initial operation, the patient presented with a fever with leukocytosis. At this time, the patient had necrotic abdominal wounds and two abdominal drains. The site of the left subclavian central catheter was normal. The chest X-ray films showed stable bilateral atelectasis and small bilateral pleural effusion.

The MICs of the two isolates were identical and are reported in Table 1. This bacterium has not been isolated in animals 5cupriavidus metallidurans, 69 ,

Type strain:. Culture col. Strain history: CIP. Cupriavidus metallidurans CH34 is a facultative anaerobe, mesophilic, Gram-negative bacterium that was isolated from decantation tank of zink factory. Note that changes will be reviewed and judged. If your changes are legitimate, changes will occur within the next Bac Dive update.

When organic carbon sources are unattainable, C. The myriad of adaptive genes within the C.

Cupriavidus metallidurans

Not distinguished from Ralstonia eutropha until Cupriavidus metallidurans is a non-spore-forming, Gram-negative bacterium which is adapted to survive several forms of heavy metal stress. Cupriavidus metallidurans is a bacterial species that belongs to the same family as Ralstonia solanacearum , a plant pathogen. This species is of ecological and industrial importance, as its relatives dominate mesophilic environments contaminated with heavy metals.

Copper Cu is important for plant growth, but high concentrations can lead to detrimental effects such as primary root length inhibition, vegetative tissue chlorosis, and even plant death. The interaction between plant-soil microbiota and roots can potentially affect metal mobility and availability, and, therefore, overall plant metal concentration. Cupriavidus metallidurans CH34 is a multi metal-resistant bacterial model that alters metal mobility and bioavailability through ion pumping, metal complexation, and reduction processes.

Interestingly, the results obtained in our study showed a drop in the c-di-GMP levels and decreased biofilm formation in P. D-galactose as carbon source GAL. Genes Dev.
