ABSTRACT
Enzymes from different sources (plants, animals, and microorganisms) have wide application in different sectors. Microbial enzymes are often more stable and useful than enzymes derived from plants or animals because of the great variety of catalytic activities available, the high yields possible, ease of genetic manipulation, regular supply due to absence of seasonal fluctuations, and rapid growth of microorganisms on inexpensive media [1]. According to a report from Business Communications Company Inc. the global market for industrial enzymes increased from $2.2 billion in 2006 to an estimated $2.3 billion by the end of 2007. It should reach $2.7 billion by 2012, a compound annual growth rate of 4%. The total industrial enzyme market in 2009 is expected to reach nearly $2.4 billion [2]. Food industry is the largest consumer of enzymes and approximately 45% of bulk share goes to it [3].
