Amylases are among the most important enzymes used in various industries. Research on amylase has progressed very rapidly over the last five decades and potential industrial applications of the enzyme especially in solid waste management have been identified. Major impediments to exploit the commercial potential of amylase are the yield, stability and cost of amylase production. Although, fungal isolates have been extensively studied by many researchers. Further, there arises a need for more efficient amylases in various sectors, which can be achieved either by chemical modification of the existing enzymes or through protein engineering. In the light of modern biotechnology, amylases are now gaining importance in biopharmaceutical applications. Still, their application in food and starch based industries is the major market and thus the demand of amylases would always be high in these sectors.
α-Amylases are one of the most popular and important form of industrial amylases and the present review point out the microorganisms that produce this enzymes
