Opis

Recent years have seen a growing interest in the application of chalcogenide nanoparticles (NPs) in various industrial sectors including energy, petroleum refining and also in the field of biology and medicine. Due to the high toxicity of chalcogen oxyanions, their release in the environment is of great concern. This book focuses on the development of a novel microbial synthesis process of chalcogenide NPs by combining biological treatment of Se/Te-containing wastewaters with biorecovery in the form of Se/Te chalcogenides NPs, and describes the enrichment of selenium oxyanion-reducing microorganisms to simultaneously remove selenite and cadmium from wastewaters.

O autorze

Joyabrata Mal was born in 1987 in Kolkata, India. Joy did his bachelor (B.Tech) in Biotechnology at West Bengal University of Technology. He later joined the Indian Institute of Technology, Guwahati, India for his master (M.Tech) of Technology degree in Biotechnology. During this degree, he did his specialization in Environment Biotechnology and worked on synthesis of biohydrogen from carbon monooxide. Joy got admitted into Erasmus Mundus Joint Doctorate Program on Environment Technologies for Contaminated Solids, Soils and Sediments (ETeCoS3) and started as PhD Fellow at UNESCO-IHE from October 2013. As part of program, he also carried out his PhD research at Université Paris-Est. and worked at University of Limoges under a short term scientific mission (STSM, COST Action ES1302). His research was mainly focused on developing novel methods for chalcogens (selenium and tellurium) bioremediation, bioreduction and recovery. He is currently a postdoctoral fellow in University of California Berkeley and working on selenium biogeochemistry.
