Abstract

As an archipelago and maritime country, Indonesia has a lot of small islands with abundance marine microorganisms which are not yet studied. Pandang Island is one of outer island of Indonesia, located in Batu Bara District, North Sumatera Province. The aims of this study were to isolate the marine sponge associated fungi, obtain potential strain against clinical pathogenic fungi and MDR bacteria, determine the best cultivation time for antibacterial production, characterize potential fungus through macro-microscopic and molecular approaches. The result showed there were 6 fungi which associated with sponge PPD.SP.7 and only fungus PDSP 7.1 could inhibit all pathogenic microorganisms. This fungus produced widest inhibition zone against S. enterica ser. Typhi in stationary phase. According to identification result, fungus PDSP 7.1 was judge as Trichoderma saturnisporum MG644629. Antimicrobial activity of this fungus was expected as the influence of the presence of NRPS gene fragments. This research is a first report which studied sponge associated fungi and its antimicrobial activity from Pandang Island, North Sumatera, Indonesia.
