Abstract
|
|
|
|
To develop natural food preservatives, methanol and water extracts were prepared from the Suaeda maritima and their antibacterial activities were examined against 12 microorganisms which were food borne pathogens bacteria, food poisoning micro-organisms and food-related bacteria. Methanol extracts exhibited antibacterial activities for the 5 Gram positve and 7 Gram negative bacteria by agar diffusion method, The antibacterial activities and cell growth inhibition were investigated on each strain with the different concentrations of Suaeda maritima extracts. Antibacterial activities were shown in root, stem, furit extracts of Suaeda maritima. However stem and fruit extracts showed weak antibacterial activity against the tested microorganisms. Root ex-tracts showed the highest antibacterial activities against microorganisms tested, such as Bacillus cereus, Bacillus subtilis, Vibrio parahaemolyticus, Staphylococcus aureus. The highest antibacterial activity against bacteria test was found in the methanol extract.
