VELKOVA, Z. I., V. K. GOCHEV, G. KOSTOV and A. ATEV, 2007. Optimization of nutritive media composition for xylanase production by Aspergillus awamori. Bulg. J. Agric. Sci., 13: 651-656
Optimization of nutritive media composition for xylanase production by Aspergillus awamori RUS-8 was carried out. Full adequate regression model was obtained by Central Composition Plan. Maximum xylanase activity was achieved in optimized nutritive media on a following composition (g/L): wheat bran-20.02; corn cobs-30.85; corn steep liquor-20.38; NaNO3-2.20; KH2PO4-1; KCl-0.5; MgSO4-0.5 and FeSO4-0.01.
