Xylanase Production by <i>Fusarium Solani</i> in Solid State Fermentation

Abstract

Xylanase constitute one of the most important groups of enzymes for commercial use. In the present study, production of xylanase was enhanced using a newly isolated F. solani SyrN7 strain from infected wheat seeds via solid state fermentation (SSF) using wheat bran as substrate. Optimum pH and temperature for enzyme production were found to be 8 and 25 °C, respectively. The wheat bran to mineral solution ratios were tested. The ratio 1:3 (w/v) yielded the highest xylanase production. Among the different nitrogen sources investigated, yeast extract was the best nitrogen source and gave the highest xylanase activity (1593 U/g). The cultivation systems can easily be modified with the above tested features and enhanced the xylanase yield by 3-fold.
