A Novel Method of Platform Chemical Production from an Engineered Electroactive Bacterium Shewanella Oneidensis MR-1 |
| 초록 |
Biological production of platform chemicals from sustainable feedstock has been the significant alternative conventional chemical refinery process. Yet the biological production process is limited by various factors, like internal redox imbalance, which is caused due to undisposed electrons, leading to high byproduct production, less conversion yield. We created a novel biorefinery system, where we demonstrate the controlling of intracellular NADH/NAD+ redox balance using chemical mediators and Terminal electron acceptors (TEA). Shewanella oneidensis MR-1 can intrinsically transfer electrons directly to electrodes through a process called extracellular electron transfer (EET) there by providing a promising approach to control internal redox status of the cells. In this study, we demonstrate the biological production of 3-HP by a recombinant S. oneidensis MR-1 dhaB gdrAB KGSADH strain with chemical mediators and TEA. |
