Genomic markers for anaerobic microbial processes in marine sediments-sulfate reduction, methanogenesis, and anaerobic methane oxidation-reveal the structure of sulfate-reducing, methanogenic, and methane-oxidizing microbial communities (including uncultured members); they allow inferences about the evolution of these ancient microbial pathways; and they open genomic windows into extreme microbial habitats, such as deep subsurface sediments and hydrothermal vents, that are analogs for the early Earth and for extraterrestrial microbiota.
海洋沉积物中厌氧微生物过程（硫酸盐还原、甲烷生成和厌氧甲烷氧化）的基因组标记揭示了硫酸盐还原、产甲烷和甲烷氧化微生物群落（包括未培养成员）的结构；它们有助于推断这些古老微生物途径的进化；并且它们为极端微生物栖息地打开了基因组窗口，例如深部地下沉积物和热液喷口，这些栖息地类似于早期地球和外星微生物群。
