||based on cell composition and known energetic costs of biochemical pathways.
||This number is calculated from the value of 0.03471 mol of ATP required per gram of cells(dry wt) presented in the reference. One E.coli cell weighs 0.28pg (dry wt), so there are 3.57 trillion cells/gram. 0.03471*6.02E23/(3.57E12 cells/g (dry wt)) gives 5.9 billion ATP/cell. See reference for more information.
