摘要：

The microbial community and extracellular polymeric substances composition of anaerobic granular sludge exposed to selenate (~10mg/L), cadmium (Cd) and zinc (Zn) (~2 and 5mg/L) were investigated by high-throughput sequencing and fluorescence excitation emission matrix (FEEM) spectra, respectively. As a response to selenate, Cd and/or Zn exposure, significant fluorescence quenching of fulvic-like acids and humic-like substances was observed. With selenate, Cd and/or Zn in the influent with respective concentrations of 10, 5 and 5mg/L, the abunda...
