background: a-amylases (ec 3.2.1.1) are covering approximately 25% of total enzyme market and are frequently used in food, pharmaceutical and detergent industries.objectives: the first ever detailed characterization of amylase from any halophilic engyodontium album is presented. materials and methods: an extracellular α-amylase was studied from halophilic e. album tistr 3645. the enzyme was ext...

bacillus sp. guf8, isolated from acidic soil samples of a tea farm was identified as bacillus cereus, based on 16s rdna sequencing and standard bacterial identification methods. following optimization of enzyme production, the resulting α-amylase was purified by acetone precipitation and ion exchange chromatography. consequently, thermostability and kinetic parameters of the purified enzyme wer...

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 ...

Background & Aim: Singhnad Guggulu is a traditional Ayurvedic formula for detoxifying and rejuvenating the joints. The present study was to investigate the α-amylase inhibition and antioxidant activities of aqueous extract of Singhnad Guggul (AESG). Experimental: α-Amylase inhibition assay by dinitro-salicylic acid method and antioxidant activity by ferric chelating and ferrous reducing assay....

Alpha-amylase E.C.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as Pseudomonas and Asperigllus, as well as muscles and ovarian tubes.1.2 Alpha-amylase from Bacillus Subtilis #1024(A TCC 465)* was purified with a highest degree of purity in our laboratory (31.59 U/mg). The extracellular alpha-amylase was subjected to differe...

the leopard moth, zeuzera pyrina, is a key and worldwide pest damaging walnut as well as many other fruit trees during the larval stages. larvae were collected from infested twigs of walnut trees. midguts from larvae were removed under a stereomicroscope and their homogenates used as the enzyme source. larval midgut extracts showed an optimum activity at ph 8.0, 6.0 and 6.0 for ?-amylase, ?- an...

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...
