ABSTRACT
Enzymes are protein catalysts of high molecular weight, which are produced not only by plants and animals but also mainly by microorganisms as a result of fermentation processes. Enzymes fall into two categories: (1) bulk industrial enzymes, which mainly include proteases for detergents, amylases for textile desizing and starch hydrolysis, pectinases for fruit-juice clarication, and proteases for the leather industry (Table 48.1); and (2) analytical enzymes.
