Microalgae-derived biochar are promising candidates to accelerate electron transfer during anaerobic digestion (AD) due inherent advantages, but the mechanisms unclear since they highly related microalgae species. In this work, distinct modulated by derived from Scenedesmus sp. (SBC) and Chlorella (CBC) were investigated two-stage AD. Overall, adding enhanced direct interspecies (DIET) increasing relative abundance of microorganisms like Firmicutes Methanosaeta. Furthermore, SBC showed a foamy honeycomb structure with abundant functional groups, rough surface, irregular holes, which provided habitats for microorganism colonization acted as an conductor facilitating conductive material-mediated DIET (i.e., cDIET). Meanwhile, CBC closed spherical granule having smooth surface low porosity, leading stack on causing bioelectrically triggered bDIET) via upregulated secretion Flavins C-type cytochromes. Results indicate that rate bDIET was one order magnitude higher than cDIET, resulting in 53.9% increase H2 yield 9.1% CH4 group compared group. These findings can enrich knowledge gaps may inspire more efficient AD processes.

This study examined the impact of sodium propionate concentration (0–40 g/L) on methanogenic archaea in an inoculum which was cultured basal nutrient medium, exploring its mechanisms and nonlinear stress intensity. The results indicated that at low concentrations, propionate-maintained homeostasis anaerobic digestion (AD) system enriched Methanosaeta. However, when exceeded 16 g/L, stability AD disrupted. pathway shifted towards a predominantly hydrogenotrophic pathway, resulting significant increase methane yield. Below concentrations 28 gradually enhanced ability to utilize orderly manner. At 24–28 genera (e.g., Advenella Methanosarcina) were adapt high-VFA environment. accompanied by upregulation genes related methylotrophic pathways, effectively mitigating inhibition enhancing methanogenesis. Conversely, excess (>30 suppressed methanogenesis-related led production arrest despite activating specialized propionate-metabolizing bacteria such as genus Pelotomaculum schinkii. As such, intensity promotes change metabolic pathways methanogens increases production; however, excessive not conducive maintaining steady state system.
