Isolation of Endophytic Fungi from Ephedra intermedia and Research Antibacterial Activity of Secondary Metabolite Produced by the Fungi

Abstract:

20 strains of endophytic fungi were isolated from roots and stems of Ephedra intermedia. After fermentation these strains, fermentation broth and mycelium were extracted by ethyl acetate, n-butanol and methyl alcohol, producing 60 extracts. Then the antibacterial activity of these extracts was researched, the result found that 33 extracted samples could evidently inhibit the growth of six different bacteria, accounted for 55%. The MIC of ethyl acetate extract of J109 was 0.15625mg/mL to five test bacterial expect Streptococcus uberi.
