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.

在含铁生境中，光铁营养生物受到反硝化作用的抑制


实验室实验表明，Fe(II) 氧化光养细菌（或光铁营养菌）被认为是太古宙和古元古代铁形成的主要沉积者，但会受到富铁系统反硝化过程中产生的有毒中间体的抑制。这确定了一个先前被忽视的压力源，该压力源在地球早期历史期间影响光铁营养生物的矿物形成。
