| Summary: | Propionibacterium acne, Bacillus cereus and Escherichia
coli are bacteria that cause infections of the skin and digestive tract in
humans. Sargassum duplicatum, one of brown macroalgae species, is
known to have the antibacterial activities. This study aims to prove
antibacterial activities of S. duplicatum lipid against three different bacteria.
The method used is the Folch method (using soxhletation, with a ratio of
chloroform: methanol 2:1, v/v) to extract lipid. Furthermore, fatty acids
content was identified by gas chromatography - mass spectrophotometry
(GC-MS). Then, the disc diffusion method was used to measure the
inhibition zone for antibacterial activity by using tetracycline as positive
control. The lipid percentage of S. duplicatum was obtained about 2.502 %
(v/w) where there were two lipid layers namely chloroform layer (0.388 %
(v/w)) and methanol layer (2.114 % (v/w)). S. duplicatum lipid contained
palmitic acid (in both layers) and oleic acid (only methanol layer).
Moreover, methanol and chloroform lipid layer (1000 mg·mL-1) of S.
duplicatum showed antibacterial activity against B. cereus, E. coli and P.
