This book is a short introduction to the basics of bioprocess technology which main principle is to harness the vast potential of microorganisms in making biochemical products. The overall subject dealt with is process by microorganisms. But the coverage goes beyond the process of biomanufacturing in the bioreactor, and extends to the factory of cell¿s biosynthetic machinery. Starting with an overview of biotechnology and organism, subsequent chapters allow students to learn about kinetic principles of reactions and cell growth. This leads to the coverage of isolation and screening processes for microbes, media formulation and sterilization, designing of reactors, monitoring and control of process parameters, recovery of products, etc. Drawing on principles from life sciences, this book is used for students in biotechnology and bioengineering. The author has used the book for a course for advanced students in life sciences.
