Method 
YATP(max) was determined by measuring the rate of oxygen consumption(QO2) and growth rate(D), and calculating the value of mol ATP formed per mol oxygen (N) and the energetic maintenance cost (M). The equation QO2 = D/YATP(max)×N + M/N was used. 
Comments 
This number is calculated from the value for YATP(max) of 13.9 in the reference. YATP(max) is the number of grams of cells (dry weight) produced per mol of ATP corrected for cellular maintenance energy costs. 1/13.9 gives 0.0719 mol of ATP per gram of cells. One E.coli cell weighs 0.28pg (dry wt) BNID 103904, so there are 3.57 trillion cells/gram. 0.0719×6.02E23/(3.57E12 cells/g (dry wt)) gives 12.1 billion ATP/cell. See BNID 101983, 101982, 104847
