Two-step purification and partial characterization of an extra cellular α-amylase from Bacillus licheniformis
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 ...

متن کاملCharacterization of an a-Amylase with Broad Temperature Activity from an Acid-Neutralizing Bacillus cereus Strain
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...
متن کاملPurification and Characterization of a Novel Thermostable and Acid Stable α-Amylase from Bacillus Sp. Iranian S1
This study reports the purification and biochemical characterization of thermostable and acidic-pH-stable α-amylase from Bacillus sp. Iranian S1 isolated from the desert soil (Gandom-e-Beryan in Lut desert, Iran). Amylase production was found to be growth associated. Maximum enzyme production was in exponential phase with activity 2.93 U ml-1 at 50°C and pH 5. The enzyme was purified by isoprop...
متن کاملPartial purification and characterization of α-amylase produced by Aspergillus oryzae using spent-brewing grains
Solid-state fermentation (SSF) was carried out to produce α-amylase from Aspergillus oryzae (IFO 30103) using spent brewing grains (SBG) as substrate. A maximum of 11296 U/gds amylase activity was obtained after 48 h of fermentation. The extracted enzyme was subjected to partial purification by ammonium sulphate fractionation. Maximum specific activity was obtained with 40-70% fraction. SDS-PAG...
