Comparison of phyla of epiphytic bacteria reported for the different phyla of macroalgae (Chlorophyta, Heterokontophyta, and Rhodophyta). Proteobacteria classes were included because some articles included this taxonomic level. The percentage values were calculated based on the total number of bacterial phyla found in the literature consulted (n = 25) and represented in a Venn Diagram to indicate the bacteria that are shared among macroalgal phyla, as well as the methodology used in each of the 25 studies (Table S1).
