Abstract: We explored the physiological and metabolic effects of different carbon sources (glucose, fructose, and glucose/fructose mixture) in phosphoglucose isomerase (pgi) knockout Escherichia coli mutant producing shikimic acid (SA). It was observed that the pgi - mutant grown on glucose exhibited significantly lower cell growth compared with the pgi + strain and its mixed glucose/fructose fermentation grew well. Interestingly, when fructose was used as a carbon source, the pgi - mutant showed the enhanced SA production compared with the pgi + strain. In silico analysis of a genome-scale E. coli model was then conducted to characterize the cellular metabolism and quantify NAPDH regeneration, which allowed us to understand such experimentally observed attenuated cell growth and enhanced SA production in glucose- and fructose-consuming pgi - mutant, respectively with respect to cofactor regeneration. © 2011 Federation of European Microbiological Societies.
