Abstract
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.
摘要
与细粒磁铁矿相关的同位素轻碳酸盐的存在主要被认为是由于环境中Fe(III)还原细菌对Fe(III)的还原作用。在此，我们报道了与反硝化作用耦合的Fe(II)生物氧化形成磁铁矿的过程。这种代谢作用提供了一种生物成因磁铁矿的替代环境来源。
