Book Description

Around the World, metal pollution is a major problem. Conventional practices of toxic metal removal can be ineffective and/or expensive, delaying and exacerbating the crisis. Those communities dealing with contamination must be aware of the fundamentals advances of microbe-mediated metal removal practices because these methods can be easily used and require less remedial intervention. This book describes innovations and efficient applications for metal bioremediation for environments polluted by metal contaminates.

Hirak Ranjan Dash completed his Ph.D. from Department of Life Science, National Institute of Technology, Rourkela, India. He did his M.Sc. Microbiology from Orissa University of Agriculture and Technology, Bhubaneswar, Odisha, India. During his research at Laboratory of Environmental Microbiology and Ecology (LEnME), he worked on the mercury bioremediation potential of marine bacteria isolated from Bay of Bengal, Odisha, India. His research interests include molecular microbiology, microbial bioremediation, marine microbiology, microbial phylogeny, genetic manipulation of bacterial systems and microbial diversity. He has developed a number of microbial techniques for assessment of mercury pollution in marine environments. Discovery of a novel approach of mercury resistance i.e. intracellular biosorption in marine bacteria has been reported by him. He has successfully constructed a transgenic marine bacterium for enhanced utilization in mercury removal by simultaneous mercury volatilization and sequestration. He has also worked in the field of genotyping and antibiotic resistance mechanism of pathogenic Vibrio and Staphylococcus spp. He has written 1 book and published 18 research papers, 7 book chapters and 10 conference proceedings in his credit.
