Strain-level beta-diversity analyses of Bray–Curtis dissimilarities of bacterial SynComs (SC, n = 37), and synthetic phycospheres (SC + C, n = 46), grown in a split gnotobiotic system. Constrained PCoA is shown for all samples (21% of variance; P < 0.001, a), or a subset of samples, depending on the content of the vessel (39.4–39.5% of variance; P < 0.001, b, c). d, e Cr growth across conditions measured using relative chlorophyll fluorescence (n = 60, d) and algal cell densities (n = 15, e). A Kruskal–Wallis test followed by a Dunn’s post hoc was used to assess significant differences among groups (P < 0.05). Corresponds to experiment H (Supplementary Fig. 1h and Supplementary Table 1).
