- •
Anaerobic and aerobic sludge were inoculated to food waste fermentation for VFA production under limited aeration condition.
- •
The maximal VFA yield was achieved at ORP in the range of −100 to −200 mV with anaerobic sludge as an inoculum.
- •
High protein degradation and VFA yield under limited aeration conditions were achieved.
- •
The low VFA production from food waste at pH 6.0 under anaerobic conditions was not caused by methanogenesis.
