Maximum amylase production was obtained at 40°C in a medium containing low starch concentrations. The enzyme displayed maximal activity at 135°C and pH 6.5 and its thermostability was enhanced in the presence of either calcium or starch. This thermostable α-amylase was used for the hydrolysis ...
The enzymatic hydrolysis properties of starch are generally determined using α-amylase and amyloglucosidase in many studies. In most mammals, starch digestion and glucose absorption occur mostly in the small intestine. The in vitro digestion of starch is generally carried out in an enzyme solution (...

The major component of starch can be hydrolyzed by a-amylase, which is present in some bacteria while well known in case of fungi. The ability to degrade starch is used as a criterion for the determination of amylase production by a microbe. ...
