α-amylases are one of the most common and important industrial enzymes widely used in various industries. The present study was conducted with aim isolating identifying symbiotic α-amylase enzyme-producing bacteria intestine Silago Sihama Rasterliger Canagorta fish living Qeshm Island, Hormozgan. intestinal these species were isolated using nutrient agar culture medium; then, producing screened...

Objective: The present study is to synthesize nanoparticles using the leaf extracts of Mimosa pudica and screen for its α-amylase inhibiting potential as well as antibacterial properties. Methods: Silver nanoparticles were synthesized using extract of Mimosa pudica leaves under various conditions such as sunlight, UV and room temperature. The synthesized nanoparticles were further characterized...

An extracellular α-amylase from Bacillus subtilis KIBGEHAS was partially purified by ultrafiltration and ammonium sulphate precipitation with 19.2-fold purification and specific activity of 4195 U/mg. The enzyme showed relatively high thermostability and retained 62% of its activity when kept at 70°C for 15 min. α -Amylase was highly stable at −18°C and loss of activity was very low during stab...

Bacillus amyloliquefaciens a-amylase (1,4-a-D-glucan glucanohydrolase. EC 3.2.1.1), which is commercially supplied as 'Bacillus subtilis a-amylase' does not cross-react immunologically with B. subtilis a-amylase. This enzyme (from B. amyloliquefaciens) was cleaved by treatment with CNBr into seven fragments. Peptide A was selected for sequence determination. It is the longest one, containing 18...

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 ...
