| Summary: | The aim of this study was to investigate the antibacterial activity of
the methanolic extracts of several alga including Sargassum oligocystum,
Turbinaria decurrens, Galaxaura rugosa, Padina minor, and seagrass
Halodule sp. In this study, antibacterial activity of the extracts were
determined using the microdilution method against Staphylococcus
epidermidis ATCC 14990 and Staphylococcus aureus ATCC 6538. The
coloring reagent, P-iodonitrotetrazolium chloride reagent was added into
the solutions to help visualizing the presence of living bacteria. In the
microdilution method, the Minimum Inhibitory Concentration (MIC) was
determined as the lowest concentration of sample that gives antibacterial
activity, meanwhile the Minimum Bactericidal Concentration (MBC) as the
lowest concentration of antimicrobial that will prevent the growth of an
organism after subculture on to antibiotic-free media. The results showed
that the methanolic extract of Halodule sp. gave MIC and MBC values at
concentration 1000μg/mL against both S. aureus and S. epidermidis. There
were no antibacterial activities observed for alga S. oligocystum, T.
decurrens, G. rugosa, and P. minor. |
