Comment on "Early Archaean Microorganisms Preferred Elemental Sulfur, Not Sulfate"

Huiming Bao,* Tao Sun, Issaku Kohl, Yongbo Peng

Philippot et al. (Reports, 14 September 2007, p. 1534) interpreted multiple–sulfur isotopic compositions of ~3.5-billion-year-old marine sulfide deposits as evidence that early Archaean microorganisms were not sulfate reducers but instead metabolized elemental sulfur. However, their data can be better explained by a scenario involving poor mixing of photochemical and surface sulfide sources.
