The application of microbiological methods to the extraction of metals from minerals is supported by several bioleaching and biooxidation processes operating in different sites over the world. This book details the basic aspects of the process with special emphasis on recent contributions regarding the chemical and microbial aspects of the bioleaching process and the use of microorganisms in the treatment of complex ores and concentrates.

Biomineralization of metal sulfides has been broadly observed in microbial cultures and in nature. However, only a few cases have been reported as biologically-controlled processes, such as greigite produced by magnetotactic bacteria. I discovered a new type of intracellular metal sulfide biomineralization, while studying the impact of copper on greigite biomineralization by the magnetotactic bacterium Desulfamplus magnetovallimortis strain BW-1.The newly discovered metal sulfide biominerals are nanoscopic particles and have an interesting crystal structure and organization. These spherical or ellipsoidal particles are composed of 1-2 nm-sized sub-grains of hexagonal copper sulfide that remains in a metastable state. The particles are located in the periplasmic space, surrounded by an organic substance. Based on these observations, it was concluded that the biomineral produced and conserved is a result of biological control. Proteomics studies with cellular and particulate samples identified several proteins associated with the process. The initial result showed that two periplasmic proteins, a heavy metal resistant protein, and a DegP-like protease, are likely working together to react to the envelope stress caused by copper. Such intracellular biomineralization is organism-specific and only initiated by the increase of copper ions, but not by other metal ions like nickel, zinc, or cobalt. Overall, my work reveals unknown features of metal sulfide biomineralization, specifically within magnetotactic bacteria.

Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of ores because as they oxidize the ore, they open up its structure, thereby allowing a gold-solubilizing agent such as cyanide to penetrate the ore. The book describes several industrial bioleaching and biooxidation processes as well as the underlying theory and biology of the microbes involved.

Although many available metal recycling methods are simple and fast, they are also expensive and cause environmental pollution. Biohydrometallurgical processing of metals offers an alternative to overcome these issues, as the use of biological means not only helps to conserve dwindling ore resources but also fulfills the need for the unambiguous need to extract metals in nonpolluting, low-energy, and low-cost way. This book covers biohydrometallurgy and its application in the recovery of metals from secondary sources like wastes. It aims to provide readers with a comprehensive overview of different wastes for metal recovery and biological treatment methods that are both environmentally friendly and economically viable.

Focusing on current and future uses of microbes as production organisms, this practice-oriented textbook complements traditional texts on microbiology and biotechnology. The editors have brought together leading researchers and professionals from the entire field of industrial microbiology and together they adopt a modern approach to a well-known subject. Following a brief introduction to the technology of microbial processes, the twelve most important application areas for microbial technology are described, from crude bulk chemicals to such highly refined biomolecules as enzymes and antibodies, to the use of microbes in the leaching of minerals and for the treatment of municipal and industrial waste. In line with their application-oriented topic, the authors focus on the "translation" of basic research into industrial processes and cite numerous successful examples. The result is a first-hand account of the state of the industry and the future potential for microbes in industrial processes. Interested students of biotechnology, bioengineering, microbiology and related disciplines will find this a highly useful and much consulted companion, while instructors can use the case studies and examples to add value to their teaching.
