Abstract: The endophytic fungi were isolated from the roots of Lavandula angustifolia Mill. by surface disinfection method and tissue isolation method,and the antibacterial activity against the Staphylococcus aureus was evaluated by paper disk diffusion method.The active isolates were identified in terms of  their morphological features by phylogenetic analysis based on ITS sequence of rDNA gene.The results showed that the endophytic fungi of YDZ-8 had remarkable antibacterial activity against Staphylococcus aureus strain CGMCC1.872.Fungal morphological and molecular identification demonstrated that the endophytic fungi strain YDZ-8 represented Trichoderma harzianum.

Key words: Lavandula angustifolia Mill., endophytic fungi, antibacterial activity, ITS sequences
