제목 Prospects of genetic engineered Shewanella oneidensis MR-1 for the production of 3-hydroxy propionic acid and its potential in Bioelectrochemical System
초록 Internal redox imbalance, which is caused due to undisposed electrons, leading to high byproduct production, less conversion yield and eventually increase the final purification cost of process, is a major hurdle in biological production of platform chemicals. Here we employed genetic engineered Shewanella oneidensis MR-1 and demonstrated the controlling of intracellular NADH/NAD+ redox balance without affecting the production in batch cultures. S. oneidensis MR-1 can intrinsically transfer electrons directly to terminal electron acceptors (TEA) through a process called extracellular electron transfer (EET). We showed the prospects of biological production of 3-HP by a recombinant S. oneidensis MR-1 dhaB gdrAB KGSADH strain grown in a conical flask as a batch culture with chemical mediators and TEA and its prospect in Electrochemical Bioreactor Array (EBA).
