Abstract:

As a probiotic with broad application value across multiple fields, Escherichia coli Nissle 1917 (EcN) is recognized as an ideal engineered chassis microbial platform, owing to its clinically validated safety, superior gut colonization capacity, and genetic compatibility with model strains. Consequently, the development of a mature genetic manipulation system for EcN is fundamental to achieving its functional applications in diverse areas. This article systematically reviews the probiotic properties of EcN, with a focus on summarizing recent advances in the development of genetic editing tools for this strain. It further sorts applications of genetically engineered EcN in therapeutic drug delivery systems for diseases (such as inflammatory bowel disease and tumor) and in efficient biosynthesis. Finally, the review explores the future directions and potential of engineered EcN strains, empowered by cutting-edge technologies like artificial intelligence, in the development of precise and safe gene editing tools, live biotherapeutics, and green biomanufacturing. This work aims to promote the widespread application of the EcN platform across various fields and provide insights and references for future research and industrial translation.
