    Abstract:
    Carbon fluxes through main pathways of glucose utilization in Escherichia coli cells--glycolysis, pentose phosphate pathway (PPP), and Enther-Doudoroff pathway (EDP)--were studied. Their ratios were analyzed in E. coli strains MG1655, MG1655(edd-eda), MG1655(zwf, edd-eda), and MG1655(pgi, edd-eda). It was shown that the carbon flux through glycolysis was the main route of glucose utilization, averaging ca. 80%. Inactivation of EDP did not affect growth parameters. Nevertheless, it altered carbon fluxes through the tricarboxylic acid cycles and energy metabolism in the cell. Inactivation of PPP decreased growth rate to a lesser degree than glycolysis inactivation.
