Saturn's satellite Enceladus is proposed to have a soda‐type subsurface ocean with temperature able to support life and an iron ore‐based core. Here, it was demonstrated that ocean chemistry related to Enceladus can support the development of Fe‐based hydrothermal vents, one of the places suggested to be the cradle of life. The Fe‐based chemical gardens were characterized with Fourier‐transform (FT)IR spectroscopy and XRD. The developed chemobrionic structures catalyzed the condensation polymerization of simple organic prebiotic molecules to kerogens. Further, they could passively catalyze the condensation of the prebiotic molecule formamide to larger polymers, suggesting that elementary biochemical precursors could have emerged in Enceladus.

基于化学生代学的土生土长的生化可能出现

土星的土卫二卫星被提议具有一种苏打型地下海洋，其温度能够维持生命并具有铁矿石基核。在这里，证明了与土卫二有关的海洋化学可以支持铁基热液喷口的发展，铁液热喷口被认为是生命的摇篮之一。铁基化学园通过傅里叶变换（FT）IR光谱和XRD进行表征。发达的化学溴化结构催化简单的有机益生元分子缩合为干酪根。此外，它们可以被动地催化益生元分子甲酰胺缩合为更大的聚合物，这表明土卫二中可能已经出现了基本的生化前体。
