Optimization of media for the maximum production of xylanase by <i>Aspergillus fumigatus </i>MKU1 was carried out using De Meo's fractional factorial desi gn with seven components such as NaNO<sub>3</sub>, K<sub>2</sub>HPO<sub>4</sub>, MgSO<sub>4</sub>, FeSO<sub>4</sub>. KCL peptone and yeast extract. <i>A. fumigatus </i>produced a maximum of 700 U/gds of enzyme after 48 hr of incubation (before optimization). After two steps of optimization, the medium designed favoured a 2.8 fold (1950 U/gds) increase in xylanase production by <i>A. fumigatus. </i>Optimized medium for <i>Aspergillus fumigatus </i>contained (g/l) NaNO<sub>3</sub>, 15 ;K<sub>2</sub>HPO<sub>4</sub>, 15 ; MgSO<sub>4</sub>, 5; FeSO<sub>4</sub>, 0.009; KCl, 0.5; peptone, 20; and yeast extract,10. |
