在罗马尼亚南部的地下水生态系统中发现的微生物垫含有化学自养细菌，它们利用硫化氢作为能量来源，固定无机碳。稳定的碳和氮同位素分析表明，这种化学自养生产是48种穴居陆地和水生无脊椎动物的食物基础，其中33种是该生态系统特有的，这是已知的唯一由原位自养生产支持的洞穴生态系统。它包含了已知的唯一以化学自养为基础的陆地群落。
Microbial mats discovered in a ground-water ecosystem in southern Romania contain chemoautotrophic bacteria that fix inorganic carbon, using hydrogen sulfide as an energy source, Analysis of stable carbon and nitrogen isotopes showed that this chemoautotrophic production is the food base for 48 species of cave-adapted terrestrial and aquatic invertebrates, 33 of which are endemic to this ecosystem, This is the only cave ecosystem known to be supported by in situ autotrophic production, and it contains the only terrestrial community known to be chemoautotrophically based.
