摘要

瓜伊马斯盆地位于加利福尼亚湾外海,是一个热液活跃的边缘盆地。由于陡峭的地热梯度和页岩侵入的局部加热,微生物基质(如短链脂肪酸和碳氢化合物)在相对较浅的深度从沉积有机物中产生。我们利用 IODP Exp. 385(U1545C 和 U1546D)取样的两个钻探地点的样本,通过纳米级二次离子质谱(NanoSIMS)和微生物硫酸盐还原率(SRR)分析了碳氢化合物对微生物吸收碳氢化合物的影响。这两个地点相距很近(约 1 公里),沉积学非常相似。U1546D 岩石经历了一个山体的侵入,此后与周围的沉积物发生了热平衡。尽管热历史不同,但这两个地点目前的地热梯度相同。山体的局部加热导致了沉积有机物的热裂解,并形成了潜在的生物有机基质。在这两个地点的一些样本中,碳氢化合物和氮的吸收水平较低,主要是在表层样本中。碳氢化合物和甲烷的添加刺激了 U1545C 站点近海底样本中的 SRR,而 U1546D 站点的样本只对甲烷产生了正反应。我们的数据表明,即使在瓜伊马斯盆地的深层地下,微生物也有代谢碳氢化合物的潜力。

Microbial anabolic and catabolic utilization of hydrocarbons in deep subseafloor sediments of Guaymas Basin.

Guaymas Basin, located in the Gulf of California, is a hydrothermally active marginal basin. Due to steep geothermal gradients and localized heating by sill intrusions, microbial substrates like short-chain fatty acids and hydrocarbons are abiotically produced from sedimentary organic matter at comparatively shallow depths. We analyzed the effect of hydrocarbons on uptake of hydrocarbons by microorganisms via nano-scale secondary ion mass spectrometry (NanoSIMS) and microbial sulfate reduction rates (SRR), using samples from two drill sites sampled by IODP Expedition 385 (U1545C and U1546D). These sites are in close proximity of each other (ca. 1 km) and have very similar sedimentology. Site U1546D experienced the intrusion of a sill that has since then thermally equilibrated with the surrounding sediment. Both sites currently have an identical geothermal gradient, despite their different thermal history. The localized heating by the sill led to thermal cracking of sedimentary organic matter and formation of potentially bioavailable organic substrates. There were low levels of hydrocarbon and nitrogen uptake in some samples from both sites, mostly in surficial samples. Hydrocarbon and methane additions stimulated SRR in near-seafloor samples from Site U1545C, while samples from Site U1546D reacted positively only on methane. Our data indicate the potential of microorganisms to metabolize hydrocarbons even in the deep subsurface of Guaymas Basin.

期刊介绍: FEMS Microbiology Ecology aims to ensure efficient publication of high-quality papers that are original and provide a significant contribution to the understanding of microbial ecology. The journal contains Research Articles and MiniReviews on fundamental aspects of the ecology of microorganisms in natural soil, aquatic and atmospheric habitats, including extreme environments, and in artificial or managed environments. Research papers on pure cultures and in the areas of plant pathology and medical, food or veterinary microbiology will be published where they provide valuable generic information on microbial ecology. Papers can deal with culturable and non-culturable forms of any type of microorganism: bacteria, archaea, filamentous fungi, yeasts, protozoa, cyanobacteria, algae or viruses. In addition, the journal will publish Perspectives, Current Opinion and Controversy Articles, Commentaries and Letters to the Editor on topical issues in microbial ecology. - Application of ecological theory to microbial ecology - Interactions and signalling between microorganisms and with plants and animals - Interactions between microorganisms and their physicochemical enviornment - Microbial aspects of biogeochemical cycles and processes - Microbial community ecology - Phylogenetic and functional diversity of microbial communities - Evolutionary biology of microorganisms
