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.

Biomass energy recovery from sewage sludge through anaerobic treatment is vital for environmental sustainability and a circular economy. However, large amounts of pharmaceutical personal care products (PPCPs) remain in sludge, their interactions with microbes enzymes would affect resource recovery. This article reviews the effects mechanisms PPCPs on treatment. Most posed adverse impacts methane production, while certain low-toxicity could stimulate volatile fatty acids biohydrogen accumulation. Changes microbial community structure functional enzyme bioactivities were also summarized exposure. Notably, such as carbamazepine bind active sites induce stress responses. The fate various during indicated that featuring electron-donating groups (e.g., ·-NH
