Abstract :In this study, the antibacterial and antifungal effects of tris-HCL, n-butanol and ethanol extracts of Pediastrum boryanum (Turpin) Meneghini (Synonym Pseudopediastrum boryanum (Turpin) E. Hegewald), cultured from benthic and pelagic habitats of the Yeşilırmak River, on various microorganism species were investigated. Antimicrobial activity tests were performed on the microorganisms Staphylococcus aureus ATCC 25923, Bacillus subtilis ATCC 6633, Listeria monocytogenes ATCC 7644, Escherichia coli O 157:H7, Pseudomonas aeruginosa ATCC 27853, Salmonella typhimurium CCM 5445, Candida albicans ATCC 10239 by disk diffusion method. As a result, in antibacterial activity tests, it was determined that the buffer extract of P. boryanum had highly effective antibacterial properties on Listeria monocytogenes ATCC 7644. It was recorded that Escherichia coli O 157:H7 strain was the most susceptible microorganism, while Bacillus subtilis ATCC 6633 strain was the most resistant microorganism; the most effective solvent was 0.5 M Tris-HCL pH: 8.00. In antifungal activity tests, it was seen that the ethanol extract of P. boryanum had highly effective antifungal properties on Candida albicans ATCC 10239.
