Mechanistic understanding of acetoclastic methanogenesis is pivotal for optimizing anaerobic digestion efficient methane production. In this study, two different operational modes, continuous flow reactor (CFR) and sequencing batch (SBR), accompanied with solids retention times (SRT) 10 days (SBR10d CFR10d) 25 (SBR25d CFR25d) were implemented to elucidate their impacts on microbial communities energy metabolism methanogens in acetate-fed systems. Microbial community analysis revealed that the relative abundance Methanosarcina (16.0% ∼ 46.0%) surpassed Methanothrix (3.7% 22.9%) each reactor. SBRs had potential enrich both Methanosarcina. Compared SBRs, CFRs lower total methanogens. exhibited a superior enrichment reactors 10-day SRT, while preferred be acclimated 25-day SRT. The mode SRT also observed affect distribution acetate-utilizing bacteria, including Pseudomonas, Desulfocurvus, Mesotoga, Thauera. Regarding enzymes involved metabolism, Ech Vho/Vht demonstrated higher abundances at compared whereas Fpo MtrA-H showed than those CFRs. genes encoding ATPase harbored by was Additionally, V/A-type (typically methanogens) CFRs, F-type bacteria) SBRs.
