For this practice-oriented textbook addressed at students of biotechnology, bioengineering, microbiology and related disciplines, the editors have brought together leading researchers and professionals across the field of industrial microbiology. After 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 highly refined biomolecules such as enzymes and antibodies, to the use of microbes in the leaching of minerals and for the treatment of municipal and industrial waste. The authors, all of whom are working or collaborating in industrial operations, give a first-hand account of the state of the industry and the future potential of microbes for industrial processes. Students interested in a career in industry will find here a highly useful and much consulted companion, while instructors can use the case studies and examples from the book to add value to their teaching.
