Enzymes are biological catalysts responsible for various metabolic processes (Chapman-Smith and Cronan, 1999). Most enzymes are purely proteins; some of the enzymes require either a co-factor (one or more inorganic ions) or a co-enzyme (organic or a metallo-organic molecule) along with the amino acid sequence for their activity (Nelson and Cox, 2004). Now a day’s enzymes are used in different industries. For example, amylases and pectinases are used in food industries, cellulases are used in bio-fuel industries and tannase is used to reduce tannic acid concentration in tannery effluent. The knowledge over the production and stability of enzymes has led researchers to develop technologies for production from cheaper substrates. The current section discusses the impending quality of the FVWs and their microbial processing to produce valuable enzymes
