The biomass fluxes are normalized by the wild-type flux GwtFBA=0.745 mmol/g DW-h in (A) and 0.908 mmol/g DW-h in (B).FURTHER READINGThe research is here: Predicting synthetic rescues in metabolic networks.An important goal of medical research is to develop methods to recover the loss of cellular function due to mutations and other defects.
