Abstract

Macroalgae that found in Pantai Barat Pasir Putih Pananjung Pangandaran, West Java is quite diverse. The three main classes of macroalgae are Clorophyceae, Rhodophyceae, and Paeophyceae found there. Five species including Ulva fasciata¸ Gelidiella acerosa¸ Halimeda sp., Turbinaria sp., and Chaetomorpha sp. representing the three main classes. Currently, marine endophytic is an interesting new source for its potential. This research was conducted to find out various endophytic microorganisms (endophytic bacteria and endophytic microfungi) that live in macroalgae’s tissue through the direct seed planting method on agar medium and their potential as antibacterial against Escherichia coli. The endophytic microorganisms obtained were purified through gram staining on bacterial isolates and moist chamber for microfungi isolates to be further identified under the microscope. Endophytic bacteria obtained as many as 17 pure isolates consisting of gram positive and negative bacillus and cocci bacteria, whereas five endophytic microfungi obtained from these macroalgae were obtained by five genera suspected of Paecilomyces sp., Mycelia sterilia, Geomyces sp., Penicillium sp., and Cladosporium sp. The endophytic bacteria isolates obtained were tested for their antibacterial activity against E. coli. The results obtained showed that there was an average of the largest inhibition zones with sensitive categories of macroalgae Halimeda sp. that is equal to 10.33 mm.
