Comments "The biomass composition was measured experimentally for S. oneidensis MR-1 grown in a lactate-limited chemostat under aerobic conditions with a dilution rate (D)=0.095h^-1 and contained 52.8% protein, 17.5% lipids, 7.7% carbohydrates, 9% RNA, and 5% DNA on a g/g AFDW (ash-free dry weight) basis. The remaining biomass constituents (peptidoglycan-2.5%, lipopolysaccharides- 3.4%, and soluble intracellular pools-3.1%) were assumed to have similar abundances as in E. coli [Neidhardt FC, Umbarger EH (1996) Chemical Composition of Escherichia coli. In: Neidhardt FC, ed. Escherichia coli and Salmonella: Cellular and Molecular Biology. 2nd ed. Washington DC: ASM Press. pp 13–16.]." Note-components add up to 101% rather than 100%
