Enzyme technology – a sub-field of biotechnology is a developing field in manufacturing in bulk and high added value in various industrial end uses both in process and product developments. Enzymes are of globular proteins and have three-dimensional structures of multi-subunit proteins. This chapter discusses the use of enzymes and their classifications based on functions and applications for industrial purposes. The chapter also discusses the mechanism of enzyme such as lock-and-key mechanism with substrate and briefs the rate of reactions such as temperature, pH, concentration and inhibitors. Today the applications of enzymes in industrial uses are very wide opportunity and will pave the new spectrum in forthcoming days. Modern biotechnology is one tool that can help meet the challenge this growth poses and also contribute to eco-friendly environment and safe to health. The chapter then discusses the present and future trends in biotechnology and has applications in many fields including organic synthesis, clinical analysis, textile processes and finishing, pharmaceuticals, detergents, food production and fermentation.
