Anaerobic fermentation is a crucial route to realize effective waste activated sludge (WAS) resource recovery and utilization, while the overall efficiency commonly restrained by undesirable disruptors (i.e., chemical dewatering agents). This work unveiled unexpectedly positive effects of biodewatering tannic acid (TA) on volatile fatty acids (VFAs) biosynthesis during WAS anaerobic fermentation. The total VFAs yield was remarkably increased 15.6 folds with enriched acetate butyrate in TA-occurred systems. TA capable disintegrate extracellular polymeric substances promote organics release. However, further modulated soluble proteins structure hydrogen bonding hydrophobic interactions, resulting decrease bioavailability consequential alteration metabolic substrate feature. These changes reshaped microbial community stimulated adaptive regulatory systems hydrolytic–acidogenic bacteria. keystone species for carbohydrate metabolism Solobacterium Erysipelotrichaceae) were preferentially enriched. Also, typical quorum sensing enhancing transport) two-component sustaining high activity) networks connectivity ecological cooperative behaviors response stress. Additionally, functions responsible hydrolysis, transmembrane transport, intracellular as well VFA showed relative abundance, which maintained activities biosynthesis. study underscored advantages treatment context deciphered interactive mechanisms.
