Abstract
Abstract1,3‐Propanediol (1,3‐PDO) has multiple practical applications, for example as an antifreeze and protective agent and as a monomer of partially renewable polyester and polyurethane. The main method for 1,3‐PDO production is currently microbial fermentation. Bio‐based 1,3‐PDO can use renewable materials as substrates, and the process is mild and environmentally friendly.Genetic engineering of microorganisms is crucial to achieve substrate diversity, reduce byproducts to decrease production costs, and facilitate the downstream processing of 1,3‐PDO. This paper reviews the metabolic engineering of 1,3‐PDO in natural and non‐natural producers. In particular, it discusses current progress using non‐natural synthetic pathways to obtain 1,3‐propanediol.Finally, strategies such as integrated production with other high‐value‐added products are proposed for successful commercialization.
