- •
Acetate production from TPW in extreme-thermophilic MCF was first investigated.
- •
Long HRT (>3 d) enhanced syntrophic acetate oxidation, causing less acetate production.
- •
Stable acetate production was achieved at a short HRT of 3 d.
- •
Coprothermobacter (main acetate-degraders) decreased when HRT dropped from 5 to 3 d.
