| Comments | "Because the theoretical maximum contribution from sulfide-using anoxygenic photoautotrophs is equal to integrated rates of sulfate reduction (38), the modern rate of net sulfide generation (2.62X10^12 mol S/year) (BNID 110486) sets an upper limit on the hypothetical contribution from anoxygenic photosynthesis to total modern primary production at 0.17% (see SI Text for calculation details)." |
