Strain of Cephalosporium having ATCC accession no. 74297, a process of isolating said strain of Cephalosporium and a process for preparing extracellular endoxylanase

摘要

Where is provided a process for preparing extracellular endoxylanase that is stable and active at high alkaline pH. The process includes growing a Ccphalosporium strain on xylan rich natural media supplemented with nitrogen-rich nutrients at high alkaline pH either by submerged or semisolid fermentation. The Cephalosporium strain has been isolated from humus rich soil collected from Ganeshkind, Pune, India and growing at high alkaline pH in a range of from 5 to 10. The strain produces an extrcelluar-cellulase-free xylanase stable and active at high alkaline pH ranging from 5 to 10.
