ABSTRACT
Enzymes are large biological molecules responsible for thousands of the chemical interconversions that sustain life. The field of industrial enzymes is now undergoing major research and development initiatives, resulting in both the development of number of new products and improvement in the process and performance of several existing products. The industrial enzyme market is divided into three application segments: technical enzymes, food enzymes and animal feed enzymes. The chapter provides information on industrially important enzymes which include: proteases, amylases, lipases, cellulases, pectinases, xylanases, glucose oxidases, catalases, glucanases, and hemicellulases. With the increase in demand for various enzymes in industries, lipase is considered as the fastest growing important group of biotechnologically relevant enzymes due to its unique characteristics. The chapter discusses eight different families of bacterial esterases and lipases. These families are: Pseudomonas Lipases, Gdsl, Streptococcus exfoliates lipase, hormone-sensitive lipase (HSL), mesophilic bacteria, smallest esterases, bacterial esterases, and Cp-lactamases.
