Purification and Characterization of Thermostable and Detergent-Stable α-Amylase from Anoxybacillus sp. AH1.
A thermostable and detergent-stable α-amylase from a newly isolated Anoxybacillus sp. AH1 was purified and characterized. Maximum enzyme production (1874.8 U/mL) was obtained at 24 h of incubation. The amylase was purified by using Sephadex G-75 gel filtration, after which an 18-fold increase in specific activity and a yield of 9% were achieved. The molecular mass of the purified enzyme was est...
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 کاملPurification and characterization of three thermostable endochitinases of a noble Bacillus strain, MH-1, isolated from chitin-containing compost.
A thermophilic and actinic bacterium strain, MH-1, which produced three different endochitinases in its culture fluid was isolated from chitin-containing compost. The microorganism did not grow in any of the usual media for actinomyces but only in colloidal chitin supplemented with yeast extract and (2, 6-O-dimethyl)-beta-cyclodextrin. Compost extract enhanced its growth. In spite of the format...
متن کاملPurification and Characterization of a Thermostable Neutrophilic Metalloprotease from Pseudomonas sp. DR89
A novel neutrophilic metalloprotease was isolated from Pseudomonas sp. DR89 isolate which was identified ina mineral spring in Iran. The enzyme was purified from the isolate to 21-folds in a three-step procedure involving ammonium sulfate precipitation, Q-Sepharose ionic exchange and Sephadex G-100 gel filtrationchromatography. Resuts showed that the enzyme was active at high temper...
متن کاملPurification and characterization of extracellular α-amylase from a thermophilic Anoxybacillus thermarum A4 strain
α-Amylase from Anoxybacillus thermarum A4 was purified using ammonium sulphate precipitation and Sephadex G-100 gel filtration chromatography, with 29.8-fold purification and 74.6% yield. A4 amylase showed best performance for soluble potato starch hydrolysis at 70 °C and pH 5.5-10.5. A4 amylase was extremely stable at +4 °C, and the enzyme retained over 65% of its original α-amylase activity a...
