Oil reservoirs contain microbial populations that are both autochthonously and allochthonously introduced by industrial development. These microbial populations are greatly influenced by external factors including, but not limited to, salinity and temperature. In this study, we used metagenomics to examine the microbial populations within five wells of the same hydrocarbon reservoir system in the Gulf of Mexico. These elevated salinity (149–181 ppt salinity, 4–5× salinity of seawater) reservoirs have limited taxonomic and functional microbial diversity dominated by methanogens,

来自墨西哥湾的高盐度油藏中的产甲烷元素
储油库中的微生物种群是通过工业发展而自发地和异源地引入的。这些微生物种群受到外部因素的极大影响,这些外部因素包括但不限于盐度和温度。在这项研究中,我们使用宏基因组学来检查墨西哥湾同一油气藏系统的5口井中的微生物种群。这些盐度较高(盐度为149-181 ppt,海水盐度为4-5倍)的储层,其分类学和功能微生物多样性有限,主要是产甲烷菌,
