AB  - An investigation was carried out to study the performance of a combined expanded 
      granular sludge bed reactor-aerobic biofilm reactor (EGSB-ABR) biosystem and key 
      microorganisms involved in this bioprocess. When the concentration of hydrolyzed 
      polyacrylamide (HPAM) was 500 mg/L, the maximum removal rate of HPAM reached 
      64.36%, among which the contribution of the EGSB reactor was 24.35%. Scanning 
      electron microscope (SEM) images and gel permeation chromatography (GPC) analysis 
      showed that macromolecular HPAM was degraded into oligomer with lower molecular 
      weight. Among the key enzymes involved in the degradation of HPAM, laccase had 
      the best tolerance to HPAM. Microbial community structure was analysed by 
      Illumina MiSeq Sequencing, which revealed that Firmicutes, Proteobacteria and 
      Bacteroidetes were the most prevalent bacterial phyla, Trichococcus, Brooklawnia, 
      Bacillus and Pseudomonas were the predominant functional genera, and Methanosaeta 
      was the dominant archaeal genus in the bioprocess. Furthermore, hypothesis about 
      the mechanisms of HPAM biodegradation was proposed.
