碳氢化合物被特殊类型的细菌、古细菌和真菌降解。以加利福尼亚湾Guaymas盆地富烃热液沉积物为模型系统，研究了它们在海相烃渗漏和沉积物中的作用及其潜在的相互作用。该沉积喷口处存在局部热液循环，将海水硫酸盐引入富含甲烷和碳氢化合物的沉积物中，从而选择了多种碳氢化合物降解群落，其中甲烷、烷烃和芳烃氧化硫酸盐还原细菌和古细菌的研究尤为深入。目前的分子和培养调查正在检测瓜伊马斯盆地热液沉积物中的多种真菌，并引起人们对可能的真菌-细菌相互作用的关注。在这篇假设和理论文章中，我们报告了背景、最近的结果和结果，以及指导2021年Edgcomb和Teske实验室当前关于该主题的实验的基本假设，我们将在对瓜伊马斯盆地深层沉积地下的细菌、古细菌和真菌群落的持续调查中重新审视这些假设。
Hydrocarbons are degraded by specialized types of bacteria, archaea, and fungi. Their occurrence in marine hydrocarbon seeps and sediments prompted a study of their role and their potential interactions, using the hydrocarbon-rich hydrothermal sediments of Guaymas Basin in the Gulf of California as a model system. This sedimented vent site is characterized by localized hydrothermal circulation that introduces seawater sulfate into methane- and hydrocarbon-rich sediments, and thus selects for diverse hydrocarbon-degrading communities of which methane, alkane- and aromatics-oxidizing sulfate-reducing bacteria and archaea have been especially well-studied. Current molecular and cultivation surveys are detecting diverse fungi in Guaymas Basin hydrothermal sediments, and draw attention to possible fungal-bacterial interactions. In this Hypothesis and Theory article, we report on background, recent results and outcomes, and underlying hypotheses that guide current experiments on this topic in the Edgcomb and Teske labs in 2021, and that we will revisit during our ongoing investigations of bacterial, archaeal, and fungal communities in the deep sedimentary subsurface of Guaymas Basin.
