莫维尔洞穴发现于1986年，是一个罕见的由原位化学自养初级生产维持的洞穴生态系统。洞穴与地表完全隔绝，主要能源为热液流体释放的硫化氢和甲烷。缩合作用和酸蚀作用共同作用于莫维尔洞的形成。无脊椎动物（其中许多是莫维尔洞穴特有的）的碳和氮同位素都比地表生物轻，这表明它们从洞穴内的化学自养初级生产者那里获得营养。本文综述了莫维尔洞穴生态系统微生物学的研究进展，重点介绍了参与硫、碳和氮循环的微生物的功能多样性，并讨论了它们在化学合成初级生产中的作用。
Discovered in 1986, Movile Cave is an unusual cave ecosystem sustained by in situ chemoautotrophic primary production. The cave is completely isolated from the surface and the primary energy sources are hydrogen sulfide and methane released from hydrothermal fluids. Both condensation and acid corrosion processes contribute to the formation of Movile Cave. Invertebrates, many of which are endemic to Movile Cave, are isotopically lighter in both carbon and nitrogen than surface organisms, indicating that they derive nutrition from chemoautotrophic primary producers within the cave. Here we review work on the microbiology of the Movile Cave ecosystem, with particular emphasis on the functional diversity of microbes involved in sulfur, carbon and nitrogen cycling, and discuss their role in chemosynthetic primary production.
