Abstract :Algae are organisms that can be used in agriculture, cosmetics, medicine, industry and many other areas thanks to the many metabolites they contain. There are thousands of species of algae. Some algae species still remain a mystery. In this study, the antimicrobial activity (against Clostridium perfringens, Enterococcus faecalis, Escherichia coli, E. coli O157:H7, Listeria monocytogenes, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus agalactiae) of extracts (18 different groups) obtained from three different algal species (Ulothrix zonata, Fontinalis antipyretica and Spirogyra gracilis) by two different methods using water, ethanol, methanol and ether were studied by disc diffusion method. According to the results obtained; each algae species, the method of extraction of the extract and the type of solvent used were found to be effective on the antimicrobial properties. In particular the extracts obtained by using the Soxhlet device (Method B) showed more antimicrobial activity against the selected microorganisms, and in this method, it was observed that the antimicrobial activityt was higher in the extracts in which ether was used as solvent.
