Facilitated methanogenesis involved in anaerobic digestion of dairy manure by soil

Shaping the microbial community involved in anaerobic digestion (AD) systems to achieve highly efficient methane production is a major challenge. In order to improve the methane recovery from dairy manure, soil, which has the potential of enhancing methane production from biomass, was used in an AD system as an additive. The results showed that the AD process performance and methane production efficiency were significantly improved by soil; an...
