In this study was aimed at identifying active substances that can be used as antibacterial agents. To reach this target, different solvent extracts (n-hexane and methanol) of microalgae strain Scenedesmus sp. AUMA-020 were examined. Phytochemical screening of n-hexane extract from microalgae strain Scenedesmus sp. AUMA-020 showed the presence of terpenoids and saponins, while methanol extracts contained flavonoids, phenolics, steroids, terpenoins and saponins. N-hexane extract has strong antibacterial activity compared to methanol extract. Both extracts isolates showed no antibacterial activity against Escherichia coli bacteria. In conclusion, the studied microalgae strain Scenedesmus sp. AUMA-020 can be considered as a potential natural source of bioactive compounds with antibacterial activity.
