Discovery metaproteomics of microbiome from Petroleum Seepage in the deep-sea

Aqueous-soluble hydrocarbons dissolve into the ocean’s interior and structure deep-sea microbial populations influenced by natural oil seeps and spills. n-Pentane is a seawater-soluble, volatile compound abundant in petroleum products and reservoirs and will partition to the deep-water column following release from the seafloor. In this study, we explore the ecology and niche partitioning of two free-living Cycloclasticus strains recovered from seawater incubations with n-pentane and distinguish them as an open ocean variant and a seep-proximal variant, each with distinct capabilities for hydrocarbon catabolism.

水溶性烃类可溶解于海洋内部，并塑造受天然油渗漏与溢油影响的深海微生物种群结构。正戊烷（n-Pentane）是一种可溶于海水的挥发性化合物，广泛存在于石油产品与储油层中，若从海底释放后会分配至深水水柱内。本研究针对从正戊烷海水培养体系中分离得到的两株自由生活噬烷菌属（Cycloclasticus）菌株，探究其生态学特征与生态位分化情况，并将二者划分为远洋变体与近油渗变体，二者在烃类分解代谢能力上各具特异性。
