The Optimization on Fermentation Condition of Endophytic Fungus No.1028 From Gingko |
|
|
Abstract The metabolites of endophytic fungus No.1028 which was isolated from the stem of Gingko had strong inhibition effect on Alternaria solani、Fusarium oxysporium、Colletotrichurm capsici、Colletotrichum gloeosporioides、Thanatephorus cucumeris and Rhizoctonia Solani . The optimum medium composition and fermentation condition of No.1028 were studied. Through orthogonal test, the result showed that the optimum medium was glucose 3.0%, corn starch 1.0%, soybean meal 2.5%, NaNO30.5%, KH2PO40.4%, FeSO40.5mg/L, CaCO30.5%. The optimum fermentation condition was culture temperature 28℃, initial pH7.0, culture time 72h, medium volumes 100mL/300mL.
