文摘
- •
Syntrophic acetate oxidation (SAO) dominates in ammonia-adapted biogas processes.
- •
SAO bacteria compete for acetate and depend on their methanogenic partner.
- •
Syntrophic acetate oxidisers are present under a wide range of operating conditions.
- •
Ammonia, acetate, temperature, retention time and trace elements influence SAO.
- •
Awareness of SAO enables strategies for process optimisation.
