Abstract:Unbalanced fermentation is a promising innovative strategy for biotechnological production processes. Guided by the genome-scale metabolic network iLJ1162, the central carbon metabolism was rewired to enhance the synthesis of (3R)-acetoin and link it to establish efficient extracellular electron transfer through unbalanced fermentation in Shewanella oneidensis. We first successfully constructed an engineered strain using glycerol as the sole carbon source to coproduce (3R)-acetoin and bioelectricity. Key engin… Show more
Our review highlights strategies for engineering electron transfer between EAMs and electrodes and discusses the challenges and prospects of these strategies in facilitating electrical energy generation and chemicals synthesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
