SW = Sargassum wightii; UR = Ulva rigida, compared statistically per microorganism at different concentrations. Data are expressed as mean ± SD, n = 3. Means within columns (for each microorganism) with different letters (a,b…) differ significantly (p < 0.05) in Duncan’s multiple comparison post hoc test.
