Fig. 2.

Correlations between lipid/water fractionation (${ϵ}_{\mathrm{L}/\mathrm{W}}$) and the relative carbon flux through 6PGDH and ICDH as well as the EMP and ED pathways. Relationships were derived from E. coli, B. subtilis, P. fluorescens strains WCS368 and 2-79, R. radiobacter, and E. meliloti. In addition, five E. coli knockout mutants lacking specific dehydrogenase and transhydrogenase genes (text) are shown in light colors. Plotted ${ϵ}_{\mathrm{L}/\mathrm{W}}$ values are calculated between the culture medium and abundance-weighted mean ${\delta }^2$H values of fatty acids. The error bars represent the corresponding abundance-weighted SD. Note that some error bars are smaller than marker sizes.
