Abstract

Abstract

As one of the most important components of microbial aggregates, the compositions and contents of extracellular polymeric substances(EPS) are closely related to the structure, functional activities and surface properties of microbial aggregates. Based on the existed research findings, the roles of EPS in maintaining the structural composition and strengthening the functional activities of microbial aggregates were systematically reviewed in this article. The modulating effects of EPS on the mass transfer performance, hydrophilia/hydrophobicity, physiochemical stability, rheological property and dewaterability of microbial aggregates are further summarized to explore the potential mechanisms involved in the influences of EPS on their functions. This article can provide a theoretical and scientific basis for improving the aggregation properties of microbial aggregates, the slurry separation efficiency and sewage treatment capacity.
