||Table in ref gives general information on quantities of macromolecules per cell. "The wet weight is calculated from the assumption that 70% of E. coli protoplasm is water (Cayley et al., 1991 PMID 1960728). The total dry weight per cell is 2.8×10^-13g. The water content (assuming that 70% of the cell is water [primary source]) is 6.7×10^-13g The total weight of one cell is 9.5×10^-13g"
