Project Title Antimicrobial properties of macroalgae
Synopsis Previous studies have showed that different solvents and extraction methods used to
prepare extracts of macroalgae affect the antimicrobial activities of the macroalgae
extracts. This study aims to compare the antimicrobial activities of water and protein
extracts of Laminaria sp. and Porphyra sp. The colony count tests against E. coli and
B. subtilis and the mycelium growth inhibition test against A. niger were carried out to
investigate the difference in antimicrobial activities of water and protein extracts of the
two macroalgae. Our results showed a significant difference in their antibacterial
activities against the bacteria studied. Findings also showed a significant difference in
antifungal activities of water and protein extracts of Laminaria sp. against A. niger.
