Evaluation of the influence of hydrodynamic conditions on biofilm development of Synechocystic salina LEGE 00041 for 42 days, on glass (A–D) and epoxy-coated glass (E–H), respectively. The analyzed parameters refer to biofilm cells (A and E), biofilm wet weight (B and F), biofilm thickness (C and G), and chlorophyll a (D and H) at two different hydrodynamic conditions (● 40 rpm; ◊ 185 rpm). Symbol * indicates significant results for p-values < 0.05, comparing the two hydrodynamic conditions.
