| Summary: | Marine algae is an incredible group of prokaryotic organisms that produce a variety of industrially
and clinically important secondary metabolites. In this study explore the marine cyanobacteria (Oscillatoria
Sp.) was isolated from the Kuantan coastal area and on their anti-microbial activity and bioactive compounds.
The ethanolic Oscillatoria Sp. extract was subjected to GC-MS analysis to determine the bioactive compounds.
Also the ethanolic extract used for antibacterial activity by disk diffusion assay using four different types of
pathogenic bacteria such as P. aurogenosa, Bacillus subtilis, Staphylococcus aureus and Escherichia coli.
The zone of inhibition was observed and measured in the experimental petri plates. The antibacterial activity
showed that the ethanol extract of Oscillatoria Sp. was effective against P. aeruginosa the 16mmzone of
inhibition was observed. The microalgae crude extract was highly significant in against tested gram-positive
bacteria. Moreover, GC-MS analysis data shows the present of several compounds such as phenol derivatives
and fatty acid derivatives in the sample. The compounds are mainly responsible for controlling the gram
positive bacteria. |
