Influence of the nature of hydrodynamic constraints on aerobic biofilms

Influence of shear stress, organic loading rate and hydraulic retention time on the biofilm structure and on the competition between different biological aggregate morphotypes

“…More recently, studies with fluidic devices have advanced our knowledge on the effect of flow on biofilm architecture (Coyte et al, 2017;Paul et al, 2012;Talvy et al, 2011;Wheeler et al, 2019;Yawata et al, 2016) and allowed to introduce a distinction between conventional biofilm (B) and streamers (S) (Ghosh et al, 2021;Scheidweiler et al, 2019;Stoodley et al, 1998;Taherzadeh et al, 2012). Streamers are structures consisting in a base attached to the support substratum and a tail elongated in the flow direction (Taherzadeh et al, 2012).…”
