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 ...

Starch hydrolysis was performed by the synergistic action of amylase and glucoamylase. For that purpose glucoamylase (Dextrozyme) and two amylases (Liquozyme and Termamyl) in different combinations were investigated. Experiments were carried out in the repetitive- and fed-batch modes at 65 °C and...

Wheat B-starch was hydrolysed by alpha-amylase "Liquozyme supra" from Bacillus licheniformis at 90 degrees C and pH 7. After 2 h, the dextrose equivalent was 18; according to size exclusion chromatography, however, the hydrolysate contained not only dominant malto-oligosaccharides with the degree...
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 (...
