【Abstract】 An endophytic fungus strain,i.e.EG4,was isolated from the leaves of Ginkgo biloba.It was identificated as Colletotrichum sp .based on morphological and taxonomic study.Furthermore,it was proved to produce flavone like compounds by TLC analysis.The culture characteristics of EG4 were also preliminarily studied.The results showed that tested carbon sources,nitrogen sources could affect EG4 growth and metabolism in different ways.Sucrose,glucose and NH + 4can clearly promote its growth; lactose and NO - 2can distinctly improve its ability to produce flavone like compounds.更多还原
