Abstract:

Low temperature anaerobic digestion,that is how to convert biomass waste into biogas effectually in low temperature,is the key technique which restricts biogas application in northern rural.This paper mainly states the current biogas application technique and existing problem,and suggests some new research theory and technology.Additionally,microbial molecular ecology and proteomics are used to ensure process of biogas production stabilization and the research development in the future are discussed.

Key words:  low temperature  biomass waste  anaerobic digestion  biogas
