چکیده
|
In present exploration, purification and characterization of xylanase was carried out to find its optimum conditions for maximum functionality. the xylanase (ec 3.2.1.8) synthesized by aspergillus niger in submerged fermentation was partially purified and characterized for different parameters like temperature, ph & heat stability. the molecular mass determined through sds-page was found 30 kda. the specific activity of the enzyme was raised from 41.85 to 613.13 with 48.63% yield just in a two step partial purification comprising ammonium sulphate precipitation and sephadex gel filteration column chromatography. the partially purified enzyme was found to be optimally active at 60°c and 7.5 ph. conclusively, for the application of xylanase in food, feed or paper manufacturing processes, it is necessary to consider its optimum ph and temperature.
