与细粒磁铁矿相关的同位素轻质碳酸盐的存在被认为主要是由于环境中Fe(III)还原细菌对Fe(III)的还原。在这里,我们报告的磁铁矿形成的生物氧化的Fe(II)耦合反硝化作用,这种代谢提供了一个替代的环境来源的生物磁铁矿。
The presence of isotopically Light carbonates in association with fine-grained magnetite is considered to be primarily due to the reduction of Fe(III) by Fe(III)-reducing bacteria in the environment. Here, we report on magnetite formation by biooxidation of Fe(II) coupled to denitrification, This metabolism offers an alternative environmental source of biogenic magnetite.
