Effects of CO2 on the Nitrogen Isotopic Composition of Marine Diazotrophic Cyanobacteria
Abstract Biological N2 fixation has been crucial for sustaining early life on Earth. Very negative δ15N values detected in Archean sediments, which are not observed in present‐day environments, have been attributed to the low efficiency of proto‐nitrogenases. Alternatively, variations in early atmos...
