Purification and Characterization of Alkaline Xylanases from Bacillus polymyxa.
By applying different classical and fast protein liquid chromatographic techniques, three xylanases (beta-1,4-d-xylan xylanhydrolase) were purified to homogeneity from the extracellular enzymatic complex of Bacillus polymyxa. The three enzymes (X(34)C, X(34)E, and X(22)) were small proteins of 34, 34, and 22 kDa and basic pIs 9.3, >9.3, and 9.0, respectively. X(34)C and X(34)E are closely relat...
متن کاملIsolation, Purification and Characterization of a Thermophilic Alkaline Protease from Bacillus subtilis BP-36
The goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native Iranian microorganisms. At the end of screening program, a Bacillus subtilis BP-36 strain producing thermophilic alkaline protease was isolated from a hot spring in Ardebil province. The target enzyme was purified using a one-step Aqueous two-phase systems (ATPS) prot...
متن کاملProduction, purification, characterization and over-expression of xylanases from actinomycetes.
Xylanases are a group of depolymerizing enzymes often used for the hydrolysis of xylan (present in hemicellulose) to monomeric sugars and comprise endo-xylanases (EC 3.2.1.8) and beta-xylosidases (EC 3.2.1.37). They often act in synergy with other enzymes for complete hydrolysis of hemicellulose. Xylanases find several industrial applications, for example in food and feed industries, paper and ...

متن کاملPartial Purification and Characterization of Alkaline Protease from Bacillus sp. Isolated from Soil
Bacillus isolates were analyzed for alkaline protease production on casein containing agar plates and identified by clear zones of casein hydrolysis around colonies. Two gram positive Bacillus isolates S5 and C3 which showed the best enzyme production were studied for purification by precipitation and dialysis. The intracellular alkaline protease enzyme was purified about 4 fold with a yield of...
