At present, the overall cost of enzyme production is very
high (due to high cost of substrates and mediums used) and
therefore, development of novel processes to increase the
yield of proteases with respect to their industrial requirements
coupled with lowering down the production cost is highly
appreciable from the commercial point of view. Furthermore,
proteases produced by using commercial medium possess
undesirable flavor, which are unsuitable for applications in food processing and pharmaceutical industries. Since the industrial use of proteases, particularly the alkaline proteases are expected to grow tremendously in the coming decade; therefore microbial proteases producing industries are always in search of new and
cheaper methods to enhance the protease production as well as to decrease the market price of this enzyme.
