摘要： Biogas fermentation is always limited or affected at low temperature conditions, one of key factors may be physiological adaption of methanogenic communities to low temperature. Howerer, biogas process could be stimulated and enhanced with addition of enriched consortia. Here, six psychroactive methanogenic consortiums were enriched as additives, and consortium E-1 was found to be most effective at 15℃. The total biogas production addition with E-1 improved 39.3% and 17.0% from pig manure and cow manure, respectively, when decreasing from 21℃ to 15℃, which is a potential microbial addition for biogas fermentation at low temperature.
