摘要
产甲烷菌是一类能够将无机或有机化合物经过厌氧发酵转化成甲烷和二氧化碳的严格厌氧古细菌,其参与的产甲烷作用通常发生在厌氧发酵过程的最后一步。发酵产物甲烷则是目前加剧全球气候变暖的一种重要温室气体。为了进一步了解不同种类产甲烷菌的生物学特性,近10年来对于产甲烷菌分离培养技术的研究不断深入并受重点关注。作者介绍了产甲烷菌的典型生境与生物学地位、产甲烷菌的分类及生理特征,并着重阐述了产甲烷菌分离纯化培养技术及培养基中不同底物与化学抑制剂对于产甲烷菌的选择作用。
Methanogen is a kind of strictly anaerobic archaea that can transform organic matter and inorganic compounds into methane and carbon dioxide in an anaerobic fermentation.Methanogenesis usually occurs in the last step of anaerobic fermentation process.Being the key part of the nature carbon cycle,end-product of methane has been ranked as a second key greenhouse gas besides carbon dioxide which exacerbate global warming trend.In order to obtain a further understanding to the biological characteristics of different kinds of methanogens,researches on laboratorial techniques of isolating and purifying methanogens are also increasingly focused in last decades.This paper thoroughly reviewed research advances on typical habitat and biological role of methanogens,species classification and their physiological characteristics with focuses on techniques of strains isolation and purification,and the selective action of various mediums for methanogens.
