Biochemical engineering is a branch of chemical engineering or biological engineering that mainly deals with the design of unit processes that involve biological organisms or molecules. Its applications are used in the food, feed, pharmaceutical, chemical, biotechnology, and water treatment industries. This edition discusses: • enzymes • enzyme kinetics • immobilised enzymes technology • industrial applications of enzymes - biotechnology of • fermentation and • industrial microorganisms • design of a fermentor • optimisation of fermentation processes n biosensors in bioprocess monitoring and control. This book is a complete treatise on biochemical engineering and also includes computer applications in fermentation technology, principles of effluent treatment, recovery and purification of fermentation products and fermentation economics. It aims to serve as a text for the undergraduate and postgraduate students in relevant disciplines and a reference for all the professionals in the related fields.
