Comments P.1 bottom paragraph: "On Earth today, oxygenic photolithotrophy assimilates carbon dioxide globally at over 100 Pg carbon per year in net primary productivity: the corresponding numbers for anoxygenic photolithotrophy and chemolithotrophy (mainly nitrification) are, respectively, 0.03–0.07 and 0.3 Pg C per year [primary sources 5,6], although anoxygenic photolithotrophy was quantitatively more important in the past [primary sources 5,6, refs 7,8]."
