Abstract

Laboratory experiments show that Fe(II) oxidizing phototrophic bacteria, or photoferrotrophs, thought to be a major depositor of Archean and Palaeoproterozoic iron formations, are inhibited by toxic intermediates produced during denitrification in iron-rich systems. This identifies a previously overlooked stressor impacting mineral formation by photoferrotrophs during early Earth history.

铁锈色栖息地的反硝化作用对光食性生物有抑制作用

实验室实验表明，在富铁系统中，反硝化过程中产生的有毒中间产物会抑制铁（II）氧化光养细菌（或称光铁嗜酸菌）的作用，而光铁嗜酸菌被认为是奥陶纪和古新生代铁地层的主要沉积物。这确定了在地球早期历史中影响光铁锈体矿物形成的一个以前被忽视的压力源。
