Purification and characterization of a thermostable xylanase from Fomitopsis pinicola.
An extracellular xylanase was purified to homogeneity by sequential chromatography of Fomitopsis pinicola culture supernatants on a DEAE-sepharose column, a gel filtration column, and then on a MonoQ column with fast protein liquid chromatography. The relative molecular weight of F. pinicola xylanase was determined to be 58 kDa by sodium dodecylsulfate polyacrylamide gel electrophoresis and by ...
متن کاملThermostable xylanase from Marasmius sp.: purification and characterization.
We have screened 766 strains of fungi from the BIOTEC Culture Collection (BCC) for xylanases working in extreme pH and/or high temperature conditions, the so-called extreme xylanases. From a total number of 32 strains producing extreme xylanases, the strain BCC7928, identified by using the internal transcribed spacer (ITS) sequence of rRNA to be a Marasmius sp., was chosen for further character...
متن کاملPurification and properties of a xylanase from Streptomyces lividans.
An extracellular xylanase produced by a cellulase-negative mutant strain of Streptomyces lividans 1326 was purified to homogeneity. The purified enzyme has an apparent Mr of 43,000 and pI of 5.2. The pH and temperature optima for the activity were 6.0 and 60 degrees C respectively, and the Km and Vmax. values, determined with a soluble oat spelts xylan, were 0.78 mg/ml and 0.85 mmol/min per mg ...
متن کاملProduction, Partial Purification and Biochemical Characterization of Thermostable Xylanase from Bacillus brevis
Additional to industrial use of xylanase in kraft pulp production, thermostable xylanase has wider application in fishery, piggery, cattle food and human food. In this research, 1-4-β-Dendoxylanase was isolated from liquid state cultures of Bacillus brevis containing wheat straw as carbon source. Xylanase was purified to apparent homogeneity by gel filtration and ion exchange chromatography. Th...
متن کاملOverexpression and single-step purification of a thermostable xylanase from Bacillus stearothermophilus T-6.
Xylanase T-6 is a thermostable alkaline-tolerant enzyme that is produced by Bacillus stearothermophilus T-6. Xylanase T-6 was found to bleach pulp effectively at pH 9 and 65 degrees C and was used successfully on an industrial-scale mill trial. To facilitate the future characterization of the protein via X-ray analysis and protein engineering, it was necessary to overexpress the enzyme in Esche...
