Research ArticleOpen accessEvery word in the titleConstruction of Recombinant Bioleaching Bacteria Thiobacillus ferrooxidans with Fluoride-Resistant ActivityYun-Chang Cao, Hong-Bo Wen, Nan Hu et al.Thiobacillus ferrooxidans is an important bioleaching bacterium, widely used in leaching, recovery of low-grade metals and environmental bioremediation. In bio-metallurgy industry, fluoride existing in some hard rock uranium deposits in south China severely affects the bacteria viability and inhibit leaching reproduction. In this study, the flr-4 gene that has strong resistance to fluorine ion in Caenorhabditis elegans, was cloned into … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 23 May 2018 · 11,341 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleFUNGAL LEACHING OF IRON ORE: ISOLATION, CHARACTERIZATION AND BIOLEACHING STUDIES OF PENICILLIUM VERRUCULOSUMNeha Chaudhary, Trina Banerjee, Neha Ibrahim, G. SibiPyrometallurgical and hydrometallurgical technologies for recovery of metals from low grade ores require high energy and capital costs. Use of microorganisms in leaching of mineral ores is gaining importance due to the implementation of stricter environmental rules. Microbes convert metal compounds into their water soluble forms and are biocatalysts of leaching processes. This study was performed to isolate and characterize … …Current Research in Microbiology, Vol. 5, Issue 1 · 25 Sep 2014 · 7,999 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material. For the expensive non-ecofriendly reasons, here we used wasted Printed Circuit Boards (PCBs) as an … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 12 Feb 2019 · 7,484 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFactors Affecting the Geometry of Silver Nanoparticles Synthesis in Chrysosporium Tropicum and Fusarium OxysporumNamita Soni, Soam PrakashProblem statement: Biosynthesis of nanoparticles using fungal cells is a novel approach to develop biotechnological possess such as bioleaching and bioremediation. In the present study, an effort was made to investigate the effect of physio-chemical parameters on the silver nanoparticle formation with the fungus Chrysosporium tropicum Carmichael and Fusarium oxysporum Schltdl. Approach: The possibilities to manipulating the geometry of silver … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 20 Jan 2012 · 19,454 accessesView PDF Cite
