In this study, exogenous N-acyl-homoserine lactones (AHLs) was added to resist the stress by high concentration (0.5 g/L) of urea formaldehyde resin microplastics (UF-MPs) on anaerobic granular sludge (AnGS), aiming to provide a viable strategy for AnGS to withstand elevated levels of UF-MPs toxicity elucidate the intricate regulatory mechanism of AHL-mediated AnGS-QS regulation. The results showed that the three different signaling molecules (C4-HSL, C6-HSL, and C8-HSL) improved the performance of AnGS under high concentration (0.

- This study analyzes how phenolic-formaldehyde resin microplastics (PF-MPs) of varying sizes impact anaerobic granular sludge (AnGS) and identifies the interactions between extracellular polymeric substances (EPS) and PF-MPs through molecular simulations and spectroscopy.
- The presence of PF-MPs creates new habitats for microorganisms, resulting in increased chemical oxygen demand (COD) removal and methane production in reactors, but also leads to the degradation of sludge particles due to high metabolic activity.
- Smaller PF-MPs can hinder sludge functions by causing mass transfer issues and undermining key biological processes, resulting in nutrient scarcity and affecting the overall performance and settling qualities of the sludge.
