Abstract:
Echinoderms are known as one of the sources that able to produce large variety of
novel bioactive compounds. COT starfish Acanthaster planci has numerous kinds of
protein or peptide which can possess wide of variety of biological activities. The
objectives of this study were to isolate proteinaceous extract from A. planci and to
evaluate anti-microbial and anti-oxidants activity of isolated protein from A. planci.
The starfish A. planci was collected from Pulau Bidong. Its body and spine part was
extracted with phosphate buffer solution and ethanol. The anti-microbial activity was
tested agaisnt pathogenic bacterial by using well-diffusion method. The anti-oxidant
activity also be tested by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging
assay.
