Exogenous inorganic pyrophosphate increases the biomass yield of Escherichia coli. In this report, we show that the effect of pyrophosphate is related to iron uptake. We have found that addition of pyrophosphate, ammonium iron (III) citrate or iron (III) chloride, in M63 minimal medium containing 1.7 microM of iron, causes an increase in growth yield. In contrast to iron chloride or ammonium iron (III) citrate, exogenous pyrophosphate is deleterious to strains unable to synthesize enterobactin… CONTINUE READING
