Described are variants of alpha-amylase enzymes for use in industrial processes, such as liquefaction of starch. The alpha-amylase variants have increased specific activity allowing the more rapidly reduction of peak viscosity during liquefaction processes. The alpha-amylase is modified by introducing ...
(6-α-glucosylmaltose). They act on starch, CDs, and maltooligosaccharides to produce large amounts of maltose and small amounts of glucose, both with an α-configuration. The activity pattern of the enzyme fromB. stearothermophilushas been extensively studied. It catalyzes hydrolysis of both ...

On Sephadex G-200, amylase from the aleurone layers is separated into seven fractions ranging in estimated molecular weights from 45,000 to 3,000. Little or no activity is observed when six fractions are subjected to electrophoresis. Electrophoresis of only the fraction with the estimated molecular...
alpha-Amylase activity on soluble starch was optimal at pH 5.0 to 6.0. The enzyme was relatively stable between pH 5.5 and 8.5 and at temperatures ... SN Freer - 《Appl Environ Microbiol》 被引量: 109发表: 2010年 Purification and characterization of a halophilic α-amylase with increased act...
2011, 47:455 Higher activity on maltose than soluble starch Monascus anka J Biosci Bioeng. 2010, 110:670 In a recent effort to improve glucoamylases, more than 100 GAs with huge diversity (down to 40–50% identity) were cloned and characterized by Novozymes. In the characterization step,...

Dextrin values should be determined to assessamylaseactivity specifically. 我们应确定糊精的值以便于存在时我们明确地评估淀粉酶的活性. 期刊摘选 Different magnetic intensities and treating times had different effects on totalamylaseactivity and IAA oxid. ...
Overall, α-amylase activity correlated with the trends obtained for starch digestibility. The inclusion of wheat starch did not affect amylase activity within species. 2013 Abro R, et al. 展开 关键词: amylases aquatic animals aquatic organisms crude protein digestibility dry matter energy fat ...
Continuous-flow potentiometric determination of α-amylase activity in serum and urine An automated saccharogenic potentiometric method for serum or urinary α-amylase is described. Amylase is allowed to act on a buffered at pH 6.9 starch solution under controlled continuous-flow conditions and the re...
