Abstract

• The isolation of endophytic fungi and antibacterial activities of some seagrasses species such as Halophila ovalis (R.Brown) Hooker.f, Thalassia hemprichii (Ehrenberg) Ascherson and Syringodium isoetifolium (Ascherson) Danty were used for the investigation. The samples of seagrasses were collected from (Lat 17˚04’20.36” N and Long 94˚27’08.01”E), Magyi coastal area, Shwe Thaung Yan Sub-township which is located at lower Rakhine Coast. The experimented seagrass samples were stored as herbarium sheets in Marine Science Department, Pathein University. Screening of marine endophytic fungi from seagrass species was carried out by Washing Method . A total of 12 marine endophytic fungi were isolated in this study, 4 different fungi from Halophila ovalis, 5 different fungi from Thalassia hemprichii and 3 from Syringodium isoetifolium. Paper disc diffusion assay method was carried out in the investigation of antibacterial activities. Among the isolation of endophytic fungi, 7 endophytic fungi named KF-01, KF-03, KF-06, KF-07, KF-08, KF-10 and KF-11 showed the antibacterial activities on Micrococcus luteus NITE83297.
