| 1 | Environmental application and ecological significance of nano-zero valent iron显示文摘Toxicity studies considering both the bare and stabilized forms of zero valent iron nanoparticles(nZVI) could be timely, given that ecological risks identified are minimized through modification or with substitution of approaches in the synthesis, development and environmental application of the nanoparticles before succeeding to volume production.This review is focused on the fate, transport and toxicological implications of the bare nZVI and surface modified particles used for environmental applications. | Biruck D.Yirsaw Mallavarapu Megharaj Zuliang Chen Ravi Naidu | 2016 | Journal of Environmental Sciences2016，28，6： | 13 |
| 2 | Mercury remediation potential of a mercury resistant strain Sphingopyxis sp.SE2 isolated from contaminated soil显示文摘A mercury resistant bacterial strain SE2 was isolated from contaminated soil.The 16 s rRNA gene sequencing confirms the strain as Sphingopyxis belongs to the Sphingomonadaceae family of the α-Proteobacteria group.The isolate showed high resistance to mercury with estimated concentrations of Hg that caused 50%reduction in growth(EC_(50)) of 5.97 and 6.22 mg/L and minimum inhibitory concentrations(MICs) of 32.19 and 34.95 mg/L in minimal and rich media,respectively.The qualitative detection of volatilized mercury and the presence of mercuric reductase enzyme proved that the strain SE2 can potentially remediate mercury.ICP-QQQ-MS analysis of the remaining mercury in experimental broths indicated that a maximum of 44%mercury was volatilized within 6 hr by live SE2 culture.Furthermore a small quantity(23%) of mercury was accumulated in live cell pellets.While no volatilization was caused by dead cells,sorption of mercury was confirmed.The mercuric reductase gene merA was amplified and sequenced.Homology was observed among the amino acid sequences of mercuric reductase enzyme of different organisms from a-Proteobacteria and ascomycota groups, | Khandaker Rayhan Mahbub Kannan Krishnan Ravi Naidu Mallavarapu Megharaj | 2017 | Journal of Environmental Sciences2017，29，1： | 10 |
