The antibacterial activity of ethanol (99.9%) extracts from marine micro-algae, namely, Mixed A (Pavlova sp., Thalassiosira weissflogii, Tetraselmis suecica and Isochrysis galbana were mixed with 1:1:1:1 ratio), Chlorella vulgaris, Nannochloropsis oculata and Chaetoceros calcitrans were estimated against food-borne bacteria, namely, Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus and Bacillus cereus. The extracts from these marine micro-algae showed potent antibacterial activity against all tested bacteria by the paper disk method. The extracts from C. vulgaris showed the strongest antibacterial activity against E. coli with minimum inhibitory concentration (MIC) of 0.62 mg/mL, and minimum bactericidal concentration (MBC) of 2.50 mg/mL. The extract from C. vulgaris contained 2 active compounds, 38.8% linoelaidic acid and 30.0% phytol. These results indicated that the ethanol extract from C. vulgaris may be a putative natural antibacterial agent against food-borne bacteria.
