Fig. 4: Genetic composition of the synthetic periphyton at the species level.

Community composition profile and relative abundances (average; n = 9) were inferred from taxonomy-based clustering at species level of assigned 18S rRNA (a) and rbcL (b) gene sequences and at genus level of assigned 16S rRNA (c) at 4 (t1), 18 (t2), and 30 days (t3) during periphyton formation. NA: not assigned species.
