| dc.description.abstract | Screening of marine bacteria producing antimicrobial was done. Thirty-six
potential isolates shown antimicrobial activity inhibition zone around colony.
Antagonistic assay showed that three isolates SB5, B03 and B04 inhibited growth of
Staphylococcus aureus, Vibrio sp.,and Candida albicans with inhibition zone of 31
mm; 27,9 mm; 26 mm respectively. Ethyl acetate extract had antimicrobial activity
against S. aureus, Eschericia coli, Bacillus subtilis, while n-hexane extract did not
show antimicrobial activity against S. aureus, E. coli, B. subtilis. Antimicrobial
activity against C. albicans was showed by methanol extract of B04, ethyl acetate
extract of SB5 and B03, and n-hexane of SB5 at high concentration. Ethyl acetate
extract of B04 and methanol, ethyl acetate, n- hexane extract of SB5 showed
antimicrobial activity against Vibrio sp. Ethyl acetate extract of SB5 had
antimicrobial activity against gram positive bacteria, gram negative bacteria and
yeast. | en_US |
