Stable isotope fingerprinting suggests progressive acetoclastic dominance and potential coal‑mediated DIET in algal hydrolysate‑lignite anaerobic co‑digestion.
Enhancing biogenic coalbed methane (CBM) production through algae-coal co-digestion has attracted increasing interest. However, the potential role of coal particles in mediating direct interspecies electron transfer (DIET) and the dominant methanogenic pathways in such systems remain unresolved. Laboratory-simulated co...
