Triazine-induced extracellular polymeric substance disruption drives metabolic reprogramming and enhanced volatile fatty acid production in sludge anaerobic fermentation
Finally, based on the VFA production profiles, samples from R1 (control) and the representative triazine-amended reactors R4 and R5 (showing pronounced VFA responses) were collected at 12d (the end of the fermentation period) and stored at -80 celsius centigrade for microbial community analysis.
