Abstract
The presence of isotopically Light carbonates in association with fine-grai ned 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 magnet ite formation by biooxidation of Fe(II) coupled to denitrification, This me tabolism offers an alternative environmental source of biogenic magnetite.
