Fig. 3: Changes of the periphyton physical structure during its establishment.

From: Synthetic periphyton as a model system to understand species dynamics in complex microbial freshwater communities

Fig. 3

Shown are representative OCT images obtained over 30 days of periphyton growth at time points t1 (A 4 days), t2 (AB 18 days), and t3 (ABC 30 days) (a). White pixel: Biomass accumulation, black pixel: absent/low biomass accumulation. Scale bar: 200 µm. Mean thickness, surface topology (relative roughness), and internal porosity (mean to max ratio of z, where z is the height of the biofilm) were determined from 20 to 30 images and 5 biological replicates per time point (b). Error bars represent standard deviations. *P < 0.05, **P < 0.005 ***P < 0.0001, post hoc Tukey test.
