Abstract: Abstract Proto-Mars growing within the solar nebula may have maintained both the hydrogen-dominated solar component and the impact degassed component enriched in H2, CH4 and CO as a proto-atmosphere. Such a proto-atmosphere would experience hydrodynamic… read more here.

DOI: 10.3389/fmicb.2022.800219
Abstract: Nitrate-dependent Fe2+ oxidation (NDFO) is a microbially mediated process observed in many anaerobic, low-nutrient (oligotrophic) neutral–alkaline environments on Earth, which describes oxidation of Fe2+ to Fe3+ in tandem with microbial nitrate reduction. Evidence suggests that… read more here.
