Alpha amylase production using microbial source and solid state fermentation has been conducted for past few years in search of thermostable enzyme. Owing to the prolific use of thermostable alpha amylase in various industries like paper, food, detergent, brewing and starch liquefaction process, the production of alpha amylase is still going on. In the present work, Bacillus subtilis (ATCC 6633...

Stimulation of the beta-adrenergic or cholinergic muscarinic receptors are the principal mechanisms by which parotid salivary secretion is regulated in vivo. In this study we have examined the effects of cholinergic stimulation on amylase gene expression in dispersed rat parotid cells. [3H]Leucine incorporation into amylase and total protein was inhibited by carbamylcholine. Within 5 min of its...

the aim of this study was production and partial purification of α-amylase enzyme by bacillus licheniformis. b. licheniformis was allowed to grow in broth culture for purpose of inducing α-amylase enzyme. optimal conditions for amylase production by b. licheniformis are incubation period of 120 h, temperature of 37 °c and ph 7.0. the α-amylase enzyme was purified by ion exchange chromatography ...

To examine further a previously reported association between amylase gene polymorphism and growth in the Pacific oyster Crassostrea gigas, ecophysiological parameters and biochemical and molecular expression levels of alpha-amylase were studied in Pacific oysters of different amylase genotypes. Genotypes that previously displayed significantly different growth were found to be significantly dif...

Background. Serum lipase and amylase are biochemical analyses used to establish the diagnosis of acute pancreatitis (AP). Despite lipase having been shown internationally to be a more sensitive and specific test, amylase remains a popular first-line test.Objective. To provide a local basis for the recommendation of the best first-line laboratory test, an assessment of their performance in our l...

Human salivary amylase and pancreatic amylase were purified and characterized. These amylases gave two bands and one band, respectively, each staining for both protein and sugar, after electrophoresis on sodium dodecyl sulfate--polyacrylamide gel. The relative molecular mass (Mr) or pancreatic amylase was calculated to be 60 000; for the two components (A and B) of salivary amylase the Mr were ...

BACKGROUND Starch-degrading amylase enzyme is important in biotechnological applications as food, fermentation, textile, paper and pharmaceutical purposes. The aim of current study to isolate alkaline thermostable α-amylase bacteria and then study the composition of medium and culture conditions to optimize cells growth and a-amylase production. MATERIALS AND METHODS Thermophilic amylase prod...

Drosophila melanogaster larvae excrete amylase and perform external digestion of their food. In this study, to investigate whether their external digestion ability varies in response to changes in the external environment, we measured the relative amount of amylase excreted by larvae using a new method: the iodine starch agar method (ISAM). Analysis using this method revealed that the amount of...

introduction and aims: noscapine has been recently known as an antagonist of bradykinin, and in this study its effect on the animal model of acute pancreatitis has been evaluated. materials and methods: 49 male wistar rats have been evaluated in five experimental and four control groups. common bile duct has been ligated by means of surgery to induce acute pancreatitis in rats. the resulted inf...
