Comments "The relative contribution of anoxygenic photoautotrophy to mid-Proterozoic PO2 need not have been large for their presence to be felt. Primary production in the modern ocean is ˜1.5X10^15 mol C/year, with an organic carbon burial rate of 5.33X10^12 mol C/year (primary sources). When primary production is 100% oxygenic, the maximum rate at which O2 can accumulate is equivalent to the rate of carbon burial (5X10^12 mol O2/year)."
