Microbial community-driven digestion patterns can be explored with metabolomics. Grass anaerobic digestion is marked by the consumption of dipeptides. Fish anaerobic digestion is marked by the consumption of biogenic amines. Adding grass did not improve the metabolic degradability of sludge. By adding 25% fish, the metabolic degradability of sludge was doubled.
