AB  - The effects of polyether sulfone (PES) microplastics and 2,4-dichlorophenol 
      (2,4-DCP) on the loosely-bound extracellular polymeric substances (LB-EPS) and 
      tightly-bound EPS (TB-EPS) of anaerobic granular sludge were investigated. In 
      addition, high-throughput sequencing technology was used to analyze the changes 
      in the microbial community and gene functions in the anaerobic granular sludge. 
      The results revealed that the chemical oxygen demand (COD) removal rates of the 
      2,4-DCP and PES+2,4-DCP experimental groups were 35% and 37%, which were 57% and 
      55% lower than that of the blank control group, while the COD removal rates of 
      the PES experimental group remained around 90%. After the addition of the PES 
      microplastics and 2,4-DCP, the protein and polysaccharide contents in the LB-EPS 
      decreased compared with the control group, and the polysaccharide content in 
      TB-EPS increased the least. In presence of the PES microplastics and 2,4-DCP, the 
      activity of coenzyme F(420) was inhibited. Through high-throughput sequencing, 
      the microbial richness and diversity of the anaerobic granular sludge in the 
      experimental group were reduced with the addition of the PES microplastics or 
      2,4-DCP. In the control group and the experimental group, the dominant bacteria 
      at the phylum level were Proteobacteria (13.45%-44.47%), Firmicutes 
      (6.86%-21.67%), and Actinobacteria (3.16%-18.11%). The abundance of 
      beta-Proteobacteria in the PES+2,4-DCP experimental group was reduced by 15.28%, 
      while the abundance of gamma-Proteobacteria increased by 28.44% compared with the 
      control group. Based on the phylogenetic investigation of the communities using 
      the reconstruction of unobserved states (PICRUSt) analysis, it was found that in 
      the experimental group with the PES microplastics or 2,4-DCP, the genes related 
      to the sludge energy metabolism function were 0.25%-0.72% more than the control 
      group; therefore, the abundance of genes related to the transport function group 
      decreased significantly.
