Abstract

Screening of marine bacteria shown thirty six isolates had inhibition zone around colony. Three potential isolates SB5, BG3 and BG4 extracted with methanol, ethyl acetate extract and n-hexane. Ethyl acetate extract had antimicrobial activity againts Staphylococcus aureus, Eschericia coli, Bacillus subtilus, while, n-hexane extract did not show antimicrobial activity againts S. aureus, E. coli, B. Subtilus. Antimicrobial activity againts C. albicans was showed by methanol extract of BG4, ethyl acetate extract of SB5 and BG3, and n-hexane of SB5 at high concentration. Ethyl acetate extract of BG4 and methanol, ethyl acetate, n-hexane extract of SB5 showed antimicrobial activity againts Vibrio sp. antimicrobial activity SB5 extracted ethyl acetate had antimicrobial activity againts gram positive bacteria, gram negative bacteria and yeast.
