Bacteria manage to constantly adapt their molecular composition to respond to environmentalchanges. We focus on systems of both metabolic and gene regulation that enablesuch type of adaptation, notably in the context of diauxic growth of Escherichia coli, when itshifts from glucose to acetate as a carbon source. To model a metabolic network, we use anapproximate kinetic formalism called linlog and address methodological issues encounteredwhen performing parameter estimation. We propose a maximum-likelihood method basedon Expectation Maximization for parameter estimation from incomplete datasets. We then apply it to the linlog model of central carbon metabolism. We also propose a method foridentifiability analysis and reduction of nonidentif...
