Bioleaching of chalcopyrite is always a challenge and research hotspot. The low copper extraction and dissolution kinetics restricted the industrial application of chalcopyrite bioleaching. To solve this problem, the dissolution process and passivation mechanism of chalcopyrite in bioleaching should be first studied, then the rate-limiting steps should be analysed explicitly, and finally the intensifying method can be put forward. Many scholars have made efforts to investigate the dissolution mechanism of chalcopyrite in bioleaching. However, there is no congruence of opinion as yet. Biohydrometallurgy of Chalcopyrite summarizes and discusses the reported research findings. In addition, this book publishes the related results found by the authors' research. Then, the dissolution mechanism of chalcopyrite in bioleaching is interpreted. Finally, the process intensification techniques of chalcopyrite bioleaching are provided and discussed. Hence, this book provides useful reference and guidance in both laboratory research and industrial production. - Interprets the dissolution mechanism of chalcopyrite in bioleaching - Provides feasible technologies for intensifying chalcopyrite bioleaching - Overviews the current situations of chalcopyrite bioleaching - Helps the readers to deeply understand the bioleaching mechanisms of chalcopyrite - Provides topics for future research and potential industrial applications

MANAGEMENT OF ELECTRONIC WASTE Holistic view of the current and future trends in electronic waste management, focusing on recycling, technologies, and regulations Management of Electronic Waste delivers a complete overview of all aspects related to the toxicity characterization of electronic wastes, along with other important topics including resource recovery, recycling strategies, biotechnological advancements, and current perspectives on waste generation and management. The book presents hazards associated with conventional recycling methods and highlights environmentally compatible economic approaches for resource recovery, along with eco-friendly strategies for management of electronic wastes. The high metallic content, heterogeneous and composite nature of e-wastes make them a rich secondary reservoir of metals. The book explores the valuable potential of e-waste and highlights the eco-friendly, sustainable technologies and recycling strategies for the profitable and effective conversion of waste to wealth. Written by a highly qualified and internationally renowned author, Management of Electronic Waste covers sample topics such as: Rise of e-waste generation paired with rising economies and mounting demand for electrical and electronic devices, with a country-by-country breakdown Status of e-waste management and recycling efforts around the world, along with key processes that drive e-waste recycling Macroeconomic trends between global demand and supply for metal resources and the transition of linear to circular economy Bioleaching, an economic and green approach for recovery of metals, from e-waste and other low grade metal repositories Different metallurgical approaches for extraction and recovery of resources from e-waste and their pros and cons Filling a gap on the understudied biotechnological recycling techniques and methods for mitigating environmental pollution caused by electronic waste, Management of Electronic Waste serves as an excellent guide on the subject for electronic waste producers, consumers, recycling industries, policy and law makers, academicians, and researchers.

Explores the utility and potential of extremophiles in sustainability and biotechnology Many extremophilic bio-products are already used as life-saving drugs. Until recently, however, the difficulty of working with these microbes has discouraged efforts to develop extremophilic microbes as potential drug reservoirs of the future. Recent technological advances have opened the door to exploring these organisms anew as sources of products that might prove useful in clinical and environmental biotechnology and drug development. Extremophiles features outstanding articles by expert scientists who shed light on broad-ranging areas of progress in the development of smart therapeutics for multiple disease types and products for industrial use. It bridges technological gaps, focusing on critical aspects of extremolytes and the mechanisms regulating their biosynthesis that are relevant to human health and bioenergy, including value-added products of commercial significance as well as other potentially viable products. This groundbreaking guide: Introduces the variety of extremophiles and their extremolytes including extremozymes Provides an overview of the methodologies used to acquire extremophiles Reviews the literature on the diversity of extremophiles Offers tools and criteria for data interpretation of various extremolytes/extremozymes Discusses experimental design problems associated with extremophiles and their therapeutic implications Explores the challenges and possibilities of developing extremolytes for commercial purposes Explains the FDA's regulations on certain microbial bio-products that will be of interest to potential industrialists Extremophiles is an immensely useful resource for graduate students and researchers in biotechnology, clinical biotechnology, microbiology, and applied microbiology.

This Encyclopedia of Biotechnology is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Biotechnology draws on the pure biological sciences (genetics, animal cell culture, molecular biology, microbiology, biochemistry, embryology, cell biology) and in many instances is also dependent on knowledge and methods from outside the sphere of biology (chemical engineering, bioprocess engineering, information technology, biorobotics). This 15-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It carries state-of-the-art knowledge in the field and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Publisher’s note: This is a 2nd edition due to an article retraction.
