| Method |
Abstract: "Simultaneous growth and riboflavin overproduction were investigated using a previously developed stoichiometric model of Bacillus subtilis metabolism. A fit of model predictions to experimental data was used to obtain estimates of fundamental energetic parameters of B. subtilis." P.750 right column bottom paragraph: "A previously constructed stoichiometric model of B. subtilis
metabolism was used as published (Sauer et al., 1998). Briefly, mass balances on cellular metabolites provide a set of linear equations relating intracellular and external fluxes." |
| Comments |
P.752 left column bottom paragraph: "Multiple terminal oxidases, which catalyze the transfer of electrons to oxygen with different energy-coupling efficiencies, exist in bacteria with branched electron transport chains such as E. coli and B. subtilis. In E. coli, the H+/e−
stoichiometry of the terminal bo and bd oxidases was determined to be 2 and 1, respectively (primary source Unden and Bongaerts, 1997), and at least 1.5 for NDH-I (primary source Bogachev, et al., 1996)." |
