Besides the high starch content, sweet potato contains endogenous amylases where the two Predominants are - and β-amylases. Sweet potato is thought to be a promising source of β -amylase since β -amylase is one of the major protein in the tubers. This investigation has focused on the properties of β amylase from white-flesh sweet potato that has been grown in Iran as a potential source for indu...

Exploring new raw starch-hydrolyzing ?-amylases and understanding their biochemical characteristics are important for the utilization of starch-rich materials in bio-industry. In this work, a novel starch-degrading ?-amylase (HL11 Amy) from Roseateles terrae HL11 was firstly reported. Evolutionary analysis revealed that HL11Amy classified into glycoside hydrolase family 13 subfamily 32 (GH13_32...

With a view to set up fast method for assessing the changes brought into starchy matrix by main processing aids (enzymes, hydrocolloids, and emulsifiers) used in bakery products, new device was tested. The Rapid Force Analyzer included fast-heating step of 90 s at constant temperature 100 °C force variations were recorded during entire assay. When wheat starch combined with three different amyl...

post endoscopic retrograde cholangiopancreatography (ercp) pancreatitis is a frequent complication either for diagnosis or treatment of pancreatobiliary diseases. a number of pharmacological agents have been tried for prevention or alleviation of the complication. allopurinol with free radical scavenger property has been considered as an effective prophylactic agent in some clinical trials. adm...

introduction: tobacco smoke is involved in the pathogenesis of several diseases in different body systems. saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. the aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...

During recent years many new and extended uses have been developed for fungal enzymes. Prominent among these are applications in the fields of food manufacturing, textile processing, and in the manufacture of malt beverages and industrial alcohol. Although certain microorganisms are capable of elaborating amylases when grown under submerged conditions either aerobically (Waldmann, 1942) or anae...

Amylase was found in high activity (193 international units per milligram protein) in the tap root of alfalfa (Medicago sativa L. cv. Sonora). The activity was separated by gel filtration chromatography into two fractions with molecular weights of 65,700 (heavy amylase) and 41,700 (light amylase). Activity staining of electrophoretic gels indicated the presence of one isozyme in the heavy amyla...

BACKGROUND Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most amylases isolated from bacteria and filamentous fungi have optimal activity above 45 °C and low pH. For example, the most commonly used industrial glucoamylases, a type of amylase t...
