| Abstract: | Optimization of media for the maximum production of xylanase by Aspergillus fumigatus MKU1 was carried out using De Meo's fractional factorial desi gn with seven components such as NaNO3, K2HPO4, MgSO4, FeSO4. KCL peptone and yeast extract. A. fumigatus 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 A. fumigatus. Optimized medium for Aspergillus fumigatus contained (g/l) NaNO3, 15 ;K2HPO4, 15 ; MgSO4, 5; FeSO4, 0.009; KCl, 0.5; peptone, 20; and yeast extract,10. |
