The objective of this study is to optimize the growth media and genes to maximize PHB production computer simulations, and to evaluate the simulation results through experiments. In order to achieve this objective, the metabolism of E. coli that produces PHB was modeled using the existing E. coli genome-scale metabolic networks. To identify the best additional nutrient for PHB production, carbon sources, minerals, amiano acids, nitrogen sources, and sulfur sources were examined by production potential analysis. Strain design was conducted to find the unwanted reactions to overexpress PHB synthesis pathway. |
