AIMS: To optimize the media components for xylanase production by Aspergillus versicolor MKU3 in solid-state fermentation (SSF). METHODS AND RESULTS: Medium optimization was carried out using De Moe's fractional factorial design with seven components. Maximum production of xylanase 3249.9 U g(-1) was obtained in SSF with an optimized medium containing (g l(-1)): NaNO(3), 20; K(2)HPO(4), 20; MgSO(4), 10; FeSO(4), 0.001; KCl, 1; peptone, 10 and yeast extract, 10. Four components namely NaNO(3), MgSO(4), peptone and K(2)HPO(4) significantly increased the xylanase production by A. versicolor MKU3. CONCLUSIONS: Fractional factorial design was used to optimize the seven components in the fermentation medium for SSF. The optimized media increased xylanase production by 3.4-fold. SIGNIFICANCE AND IMPACT OF THE STUDY: Aspergillus versicolor MKU3 produced maximum xylanase after two steps of media optimization under alkaline condition. This medium will be significant value for xylanase production in SSF. |
