To investigate the impact of sulfate (SO42-) on performance bioelectrochemical up-flow anaerobic sludge blanket (BE-UASB), COD/SO42- ratio sulfate-containing methanolic wastewater was gradually decreased from 20 to 3. The results showed that BE-UASB maintained higher COD and SO42- removal (i.e., 91% 70%, respectively) with methane production rate 278.7 mL/Lreactor/d at 10 5, ensuring efficient energy recovery. Sulfidogenesis enabled re-granulation while bioelectrocatalysis further contributed growth/proliferation biomass interwoven filaments, rods, spherical microorganisms. 16S rRNA gene analysis demonstrated promoted diversity methane-producing archaea (MPA), including Methanomethylovorans, Methanosaeta, Candidatus_Methanofastidiosum, Methanobacterium. Sulfate-reducing bacteria (SRB), mainly comprising G_norank_f_Syntrophobacteraceae, Desulfomonile, Syntrophobacter, tended be enriched bioelectrodes, which not only eased competition MPA but also achieved simultaneous in synergy MPA.

Acidogenic fermentation is a technology that involves halting methanogenesis in the conventional anaerobic digestion process to produce mainly volatile fatty acids (VFAs). VFAs serve as direct precursors energy-rich or higher value-added products upon undergoing additional processing. In this study, batch reactors were utilized assess individual and interaction effects of time pH variables on VFA production from acidogenic cassava wastewater through establishment completely randomized design second-order response surface (rotatable central composite design), respectively. The maximum observed was 3444.04 mg acetic acid (HAc)/L (0.58 gCODVFA/gCOD) 6 days, with (48.5%), propionic (28.3%), butyric (13.6%) identified main metabolites. Additionally, assessment effect pH, reached 2547.72 mgHAc/L (0.34 at 5.9, predominant organic acid. Statistically, individually affect wastewater; however, between them generated non-significant effect.

Abstract The valorization of vinasses into short-chain fatty acids (SCFAs) via anaerobic fermentation (AF) is an emerging approach that remains under research. Given the diverse microbial metabolisms simultaneously occurring in AF, control operational parameters essential to avoid process destabilization. To unravel their effect, novelty this investigation relied on evaluation robustness AF against perturbation deliberately set (i.e. hydraulic retention time (HRT) and temperature increase). Regardless applied perturbation, similar yields (0.5–0.6 g COD-SCFAs/g VS ) were attained. However, selected perturbations exerted effect microbiome development. Whereas increase mediated a 49.70% dissimilarity, only 21.91% dissimilarity was caused by HRT increase. Microbial analysis revealed Clostridiales, Prevotella Megasphaera as key bacteria degradation. bioconversion obtained despite different microbiomes developed after each suggested functional redundancy highlighting robustness. These findings evidenced feasible biotechnology further valorize vinasse SCFAs, demonstrating stability common might be encountered at industrial scale.
