Elemental composition - percent oxygen in dry mass

Value 20 %
Organism Bacteria Escherichia coli
Reference Physiology of the Bacterial Cell: A molecular approach Authors: Frederick Neidhardt, John Ingraham, and Moselio Schaechter Page: 3
Comments Not written explicitly but probably by mass. Note: BNID 101 800, Empirical elemental formula for biomass in E. coli, gives C:H(1.77):O(0.49):N(0.24). From this it can be calculated that carbon is ~48% and oxygen is ~31% of dry cell mass. The difference between 31% and 20% may be due to different growth conditions resulting in different composition.
