Abstract:
Microalgae are important biological resources in a wide range of applications of biotechnology. In this study, microalgae Chlorella vulgaris isolated from Chabahar Bay and its antibacterial activity of organic extracts against three strains of Gram-negative bacteria; E. coli, Proteus vulgaris, Vibrio chlorella and two strains of Gram-positive bacteria Listeria monocytogenes and Staphylococcus aureus was examined. Ethanol and chloroform extracts obtained by disk diffusion and successive dilution methods for determining the minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) were determined. Based on the results, the ethanol extracts has greatest effect on bacterium V. chlorella and the MBC for E. coli bacteria. The chloroform extract showed the greatest effect on the bacterium P. vulgaris and with different concentrations and minimal bactericidal concentration for all tested bacteria were obtained. Overall Iranian local microalgae Chlorella vulgaris has a strong antibacterial effect and Chloroform extract against ethanol extract has a more effect on the bacteria.
