Cupriavidus sp. strain BIS7 is a Malaysian tropical soil bacterium that exhibits broad heavy-metal resistance [Co(II), Zn(II), Ni(II), Se(IV), Cu(II), chromate, Co(III), Fe(II), and Fe(III)]. It is particularly resistant to Fe(II), Fe(III), and Zn(II). Here we present the assembly and annotation of its genome.

Concentrations of selected trace minerals (Cu, Fe, Zn, Mn, Co, Se) were determined from annual cool-season grass pasture forages over four consecutive winter-spring grazing seasons (2001-2005). Twice monthly forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously. Each e...

BACKGROUND Heavy metals are ubiquitous elsewhere in nature and their measurement in environment is necessary to develop health management strategies. In this study, we aimed to find out concentrations and spatial patterns of heavy metals in main farms of Sanandaj in Kurdistan, Iran. METHODS Over May to October 2012, six farms were selected to analyze concentrations and spatial patterns of sev...

New highly mixed phases have been identified in Cu/ZnO systems by EXAFS and XANES at both the Cu and Zn K-edge. The phases were generated by ball-milling Cu(2)O/ZnO mixtures under three different atmospheres of synthetic air (SA), SA + CO(2) and CO(2). The system milled in CO(2) shows disproportionation of Cu(2)O into Cu(0), Cu(1+) (cuprite Cu(2)O-type phase) and Cu(2+) (tenorite CuO-type phase...

Brucella Cu-Zn superoxide dismutase (Cu-Zn SOD) is a periplasmic protein, and immunization of mice with recombinant Cu-Zn SOD protein confers protection against Brucella abortus infection. However, the role of Cu-Zn SOD during the process of Brucella infection remains unknown. Here, we report that Cu-Zn SOD is secreted into culture medium and is translocated into host cells independent of type ...

This study provided a picture of the spatial and temporal distributions of Cr, Co, Ni Cu, Zn, As, Cd and Pb in bottom sediments of Tolo Harbour. The concentrations of the eight heavy metals differed significantly between sites due to the poor tidal flushing in Tolo Harbour. The levels of Cu, Zn, Cd and Pb were generally enriched in sediments from inner Tolo Harbour, while sediments from outer T...

concentrations of major nutritional and trace elements (ca, p, mg, na, k, fe, zn, cu, mn, se,co, cr, ni, sr, ba) and toxic heavy metals (cd, pb) were analyzed in the meat of limousin, red angus andsalers bulls. elements were determined using inductively coupled plasma emission atomic spectrometry. theconducted research showed that the meat of compared breeds differed in the concentrations of cu...

We have presented a detailed theoretical (density functional theory and ONIOM) study on the structure and M-PrP (prion protein) interaction on various prion models, M(PrP) systems (where PrP = HGG, HGGGW x 3H(2)O, and PrP(61-84), and M = Zn, Cu, Ni, Co, Fe, Mn). It was shown that the geometry of the complex [Mn(HGGGW)(H(2)O)] x 2H(2)O is quite different for M = Mn(III) and Mn(II), and partial u...
