Abstract

Background: Increasing the resistance of pathogenic bacteria to antibiotics is the new challenges for human Bing. Seaweeds are good sources of raw material for drug products due to the abundance and diversity of secondary metabolites. The major secondary metabolites of marine algae are halogenated compounds, which show antimicrobial, antifungal and antiviral properties.
Materials and Methods: The extraction procedure was conducted by maceration and ultrasounication with organic solvents include methanol and n-hexane. The disk diffusion test, MIC and MBC study was conducted to evaluate the antimicrobial properties against bacteria. Data analysis was performed by One Way ANOVA.
Results: In this study, Listeria monocytogenes showed highest sensitivity to n-hexanic extract of algae Dictyota cervicornis in 1/5 dilution W/V, in compare to the dilution of 1/10 and 1/15W/V (p>0.05). Soaking method extracts didn’t show any significant effect against the studied bacteria.
Conclusion: based on the results, n-Hexanic extract of the Dictyota cervicornis algae showed better antibacterial effects in compare to the Methanolic extract and soaking method. But if biochemical composition of the extract could be recognize, the antibacterial effect of the extract could be enhanced.
