Microbial enzymes are in great demand owing to their
importance in several industries such as brewing, baking,
leather, laundry detergent, dairy. starch processing and
textiles besides pharmaceuticals. About 80% of the enzymes
produced through fermentation and sold in the industrial scale
are hydrolytic enzymes. Due to recognition of new and new
applications, an intensive screening of different kinds of
enzymes with novel properties, from various microorganisms, is
being pursued all over the world. Bacillus sp are largely known to produce a-amylase, among the different groups of microoganisms, at industrial level. They are known to produce both saccharifying and liquefying a-amylases (Fukumoto 1963; walker and Campbell, 1967a). which are distinguishable by their mechanisms of starch degradation by the fact that the saccharifying asamylases produce an increase in reducing power about twice that of the liquefying enzyme (Fukumoto, 1963; Pazur and Okada, 1966). Under this circumstances, the present study was
undertaken, with a View to utilise a fast growing B.coagu1ans
isolated from soil, for production of thermostable and
alkaline oz-amylase under different fermentation processes |
