Molecular choreography of sludge extracellular polymeric substances-From biomolecule identification to energetics and assembly dynamics.

ABSTRACT: Extracellular polymeric substances (EPS) shape the immediate environment for microbial survival and biofilm formation. Dynamic agglomeration of EPS dominates the formation kinetics and structural properties of activated sludge flocs as a consequence of biopolymer interactions across the wastewater treatment process. Current partial understanding and imprecise modeling of the structure hinder the comprehensive elucidation of the dynamic reorganization of clusters as component interactions change, causing a gap in the fundamental knowledge of EPS generation and functions. Here, biopolymer models of aerobic activated sludge and anaerobic digestion sludge (ADS) were constructed through molecular screening, and the dynamic landscape of EPS multicomponent clusters was then captured by an extensi
