Comments This corresponds to ~1mM Po4 according to the following calculation: molecular mass of Po4=31+4×16=95g. 1M=95g/liter. 1mM=95mg/liter˜100mg/liter. liter of water=kg. 100mg/liter=100mg/kg=100µg/g=0.1µg/mg. Taking 0.3 µg/mg dry biomass as an intermediate value, and dry weight as ~0.333 of cell weight (BNID 100044) 0.3 µg/mg dry weight=0.1µg/mg (total) weight˜1mM. For value of 10mM see BNID 105540
