WebTo arrive at the number of ATP molecules per cell, one needs to know the dry weight of an average E. coli, which is taken to be 0.28 pg (Neidhardt et al. 1990) (BNID 100008) or 3.6 trillion cells/g. Cell size is dependent on growth rate and the value of 0.28 pg is for a growth rate of 0.66, (doubling time 40 minutes). WebE. coli weight collected was very similar – around 190 g.
