Summary of key findings 1. PAOs, cultivated with acetic or propionate acids, can uptake acetic acid, propionic acid, butyric acid, valeric acid and iso-butyric acid. 2. GAO, cultivated with acetic acid, can utilize propionate acids at the similar uptake rate as PAO, which has not been observed in room temperature (20 ℃) culture before. 3. GAO, cultivated with acetic acid, seemed to be competitive since it can use many types VFAs at equivalent rates as PAOs. 4. GAO, cultivated with propionate acid, did not seem to be competitive since it cannot utilize other types VFAs like PAOs did.
