| 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) (primary source) 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)." |
