Membrane fouling related to microbial community and extracellular polymeric substances at different temperatures

- Low temperature caused faster membrane fouling than high temperature in A/O-MBR.
- Extracellular polymeric substances were changed with varying temperatures.
- Polysaccharides dominated metabolites at 303 and 293 K, instead of protein at 283 K.
- Changing of microbial community could responsible for variation of metabolites.
- Microbial community was the core during the process of membrane fouling.
