The epsilon-proteobacteria have recently been recognized as globally ubiquitous in modern marine and terrestrial ecosystems, and have had a significant role in biogeochemical and geological processes throughout Earth's history. To place this newly expanded group, which consists mainly of uncultured representatives, in an evolutionary context, we present an overview of the taxonomic classification for the class, review ecological and metabolic data in key sulphidic habitats and consider the ecological and geological potential of the epsilon-proteobacteria in modern and ancient systems. These integrated perspectives provide a framework for future culture- and genomic-based studies.
ε-变形菌纲最近被认为在现代海洋和陆地生态系统中普遍存在，并且在地球历史上的生物地球化学和地质过程中发挥了重要作用。为了将这个主要由未培养代表组成的新扩展类群置于进化背景中，我们概述了该纲的分类学分类，回顾了关键硫化物生境中的生态和代谢数据，并考虑了ε-变形菌纲在现代和古代系统中的生态和地质潜力。这些综合观点为未来基于培养和基因组的研究提供了一个框架。
