^a 'Y_i/j' is the yield of i on j (i.e. production of i divided by consumption of j). 'cypc' denotes moles of nitrogen fixed and stored as cyanophycin, while 'PG' represents Cmoles of polyglucose.

^b 'SO₄^' represents moles of sulfate used as an oxidant.

^c 'X' represents Cmoles of biomass.

^d 'ATP' represents moles of ATP available for cellular maintenance.

^e 'syn' designates a parameter associated with the Synechococcus guild. 'FAP' indicates a parameter associated with the filamentous anoxygenic phototroph guild and 'SRB' denotes a parameter associated with sulfate-reducing bacteria guild.
