oxic

The only known barrier to aerobic growth on citrate is its inability to transport citrate under oxic conditions (41 – 43).

A more likely possibility, in our view, is that an existing transporter has been coopted for citrate transport under oxic conditions.

The inability to use citrate as an energy source under oxic conditions has long been a defining characteristic of E. coli as a species (35, 36).

Tamzek asserts that the mineral uraninite, present on the early Earth, cannot form under “significant exposure to oxygen”, however a recent publication from the Nasa Astrobiology Institute stated that its P.I. had observed the, “survival of uraninite … under an oxic atmosphere” and instability of uraninite under an oxygen-poor atmosphere, which was said to be “supporting … evidence for … an oxic Archaean atmosphere.”

Given that red beds–supposedly evidence of an oxic atmosphere, have been found contemporary with banded iron formations, it seems difficult to determine if the atmosphere strongly affects either of their formation, it is likely that neither are good indicators of atmospheric composition.
