Screening of Antibacterial Strains from Endophytic Fungi in Ginkgo Leaves

480 strains of endophytic fungi from ginkgo leaves were isolated, which were identified as Ascomycota, Colletotrichum gloeosporioides, Sphaeropsidaceae, Colletotrichum, Chaetomium, Nigrospora, Alternaria and Pestalotiopsis based on morphological taxonomy. And the proportion of dominant fungi Ascomycota was 46.3%. Anti-bacteria experiments were carried out to show their inhibition to E.coli. 2 strains, S.aureus and Pseudomonas aeruginosa, obviously inhibited Sphaeropsidaceae and Colletotrichum gloeosporioides, especially E.coli.
