*Co-digestion effect > 1 indicates a synergistic effect.
*Co-digestion effect = 1 indicates no effect.
*Co-digestion effect < 1 indicates an antagonistic effect.
aThe experimental enzyme activity or VS removal efficiency represents the total amount of enzyme activity or VS removal efficiency generated in each proportion from the cultivation process, and the calculated enzyme activity or VS removal efficiency was calculated from the enzyme activity or VS removal efficiency of the individual substrates in each microorganism source (based on mL) contained in the proportions.
