Improvement of xylanase production by Cochliobolus sativus in solid state fermentation.

Abstract

The xylanase production by Cochliobolus sativus strain Cs6 was improved under solid state fermentation (SSF). High xylanase activity (1079 U/g) was obtained when wheat straw was used after 8 days of incubation. Combinations of sodium nitrate with peptone or yeast extract resulted in an increased xylanase production (1543 and 1483 U/g, respectively). The Cs6 strain grown in SSF in a simple medium, proved to be a promising microorganism for xylanase production.
