Abstract

• In this study, ten endophytic fungal strains were isolated from the plant parts of Hesperethusa crenulata (Roxb.) Roem. sample 1 and six fungal strains were also isolated from the plant parts of Hesperethusa crenulata (Roxb.) Roem.sample2. Hesperethusa crenulata (Roxb.) Roem. sample 1 was collected from Ayartaw Township, Saging Region and Hesperethusa crenulata (Roxb.) Roem. Sample 2 was also collected from Yay Sa Kyo Township, Magway Region. The morphological characters of isolated fungal strains were conducted at Microbiology Laboratory, Department of Botany, University of Yangon and microscopic characters were investigatedat Universities’ Research Center, YU. In the present study, strains HH 1, 2, 9 and 13 were identified as Cephalosporium sp. and strain HH 12 was Rhizoctonia sp.. Antimicrobial activities of all isolated strains were conducted by using paper disc diffusion assay with eight test organisms. All isolated strains were exhibited antimicrobial activity on Agrobacterium tumefaciens, Aspergillus flavus, Bacillus subtilis, Candida albicans, Malassezia furfur, Micrococcus luteus, Salmonella typhus and Xanthomonas oryzae.
