Abstract

Microbial degradation influences the quality of oil resources. The environmental factors that shape the composition of oil microbial communities are largely unknown because most samples from oil fields are impacted by anthropogenic oil production, perturbing the native ecosystem with exogenous fluids and microorganisms. We investigated the relationship between formation water geochemistry and microbial community composition in undisturbed oil samples. We isolated 43 microliter-sized water droplets naturally enclosed in the heavy oil of the Pitch Lake, Trinidad and Tobago. The water chemistry and microbial community composition within the same water droplet were determined by ion chromatography and 16S rRNA gene amplicon sequencing, respectively. The results revealed a high variability in ion concentrations and community composition between water droplets. Microbial community composition was mostly affected by the chloride concentration, which ranged from freshwater to brackish-sea water. Remarkably, microbial communities did not respond gradually to increasing chloride concentration but showed a sudden change to less diverse and uneven communities when exceeding a chloride concentration of 57.3 mM. The results reveal a threshold-regulated response of microbial communities to salinity, offering new insights into the microbial ecology of oil reservoirs.

摘要

微生物降解会影响到油资源的质量。影响油微生物群落组成的环境因素在很大程度上是未知的，因为大多数油田样本都受到人为采油的影响，与外源流体和微生物一起破坏了自然生态系统。我们研究了未受干扰的油样本中地层水地球化学与微生物群落组成之间的关系。我们从特立尼达和多巴哥彼奇湖的重油中分离出 43 个微升大小的水滴。通过离子色谱法和 16S rRNA 基因扩增子测序分别测定了同一水滴中的水化学和微生物群落组成。结果表明，水滴之间的离子浓度和群落组成存在高度可变性。微生物群落组成主要受氯离子浓度的影响，氯离子浓度范围从淡水到半咸水。值得注意的是，微生物群落并没有随着氯离子浓度的增加而逐渐响应，而是在超过 57.3 mM 的氯离子浓度时，突然变得多样性降低且群落分布不均匀。研究结果揭示了微生物群落对盐度的响应存在一个阈值调节，为油藏微生物生态学提供了新的见解。
