Direct interspecies electron transfer (DIET) provides an innovative way to achieve efficient methanogenesis, and this study proposes a new approach upregulate the DIET pathway by enhancing quorum sensing (QS). Based on long-term reactor performance, QS enhancement achieved more vigorous methanogenesis with 98.7% COD removal efficiency. In control system, failure occurred at accumulated acetate of 7420 mg COD/L lowered pH 6.04, much lower 41.9% was observed. The significant in QS-enhancing system supported higher expression conductive pili c-Cyts cytochrome secretion-related genes, resulting 12.7- 10.3-fold improvements. Moreover, also improved energy production capability, increase F-type V/A-type ATPase 6.3- 4.2-fold, effect probably provided for nanowires secretion. From perspective community structure, increased abundance Methanosaeta Geobacter from 54.3 17.6% 63.0 33.8%, respectively. Furthermore, genes involved carbon dioxide reduction alcohol dehydrogenation 0.6- 7.1-fold, Taken together, indicates positive effects chemicals stimulate advances understanding environments such as anaerobic digesters sediments.

Bioelectrochemical anaerobic digestion (BEAD) is a promising next-generation technology for simultaneous wastewater treatment and bioenergy recovery. While knowledge on the inhibitory effect of emerging pollutants, such as microplastics, conventional processes increasing, impact microplastics BEAD process remains unknown. This study shows that methane production decreased by 30.71% when adding 10 mg/L polyethylene (PE-MP) to systems. The morphology granular sludge, which was biocatalysts in BEAD, changed with microbes shedding granule crack PE-MP existed. Additionally, presence shifted microbial communities, leading lower diversity but higher richness tight clustering. Moreover, fewer fermentative bacteria, acetogens, hydrogenotrophic methanogens (BEAD enhanced) grew under stress, suggesting had an methanogenic pathways. Furthermore, abundance genes relevant extracellular electron transfer (omcB mtrC) (hupL mcrA) decreased. efficiency reduced cytochrome c down system activity. Finally, phylogenetic investigation communities reconstruction unobserved states analysis predicted decrease key enzymes, including EC 1.1.1.1 (Alcohol dehydrogenase), 1.2.99.5 (Formylmethanofuran 2.8.4.1 (Coenzyme-B sulfoethylthiotransferase). Altogether, these results provide insight into inhibition mechanism recovery further optimisation process.
