摘　　要：嗜冷产甲烷菌在全球碳素循环中发挥了非常重要的作用,近年来引起了国内外学者的广泛关注。尽管已知冷适应的产甲烷古菌在低温厌氧消化中发挥着重要作用,但目前获得培养的嗜冷产甲烷古菌却很少。综述了嗜冷产甲烷菌的研究进展,阐述了嗜冷产甲烷古菌的分离、嗜冷机制及分子生物学技术的应用,并对嗜冷产甲烷菌在低温厌氧消化中的应用进行了分析。Psychrophilic methanogens play a very important role in global carbon cycle, and attract more and more research interests. Though playing an important role in low-temperature anaerobic digestion, the so-far cultured cold-adaptive methanogenic strains are very few. The re- search progress of Psychrophilic methanogens was reviewed, with the focus on their classification, isolation and cold-adapted mechanisms, as well as the molecular biology techniques. The application of Psychrophilic methanogens in low-temperature anaerobic digestion was also analyzed.
