Cable bacteria are a new group of filamentous electroactive microorganisms with the ability of long-distance electron transfer (LDET), playing an important role in the geochemical cycling of elements. Their unique structural and functional characteristics make them like "biological cables". Since the first discovery in marine sediments in 2012, cable bacteria have attracted widespread attention. They have shown unique ecological potential in maintaining the health of aquatic ecosystems, environmental restoration, and climate regulation. Focusing on the "biological cable" structures and functions of cable bacteria, this paper reviews their filamentous structural characteristics, electrogenic sulfur oxidation characteristics, diversity and distribution characteristics, and LDET mechanism in sediments, and summarizes their influences on the cycling of key elements such as S, C, N, and P and the migration and transformation of metal ions. In addition, this paper summarizes the interactions of cable bacteria with other organisms and their roles in the natural restoration of ecosystems and analyzes the existing problems and future development directions, with a view to providing a reference for further giving play to the role of "biological cables" in the natural restoration of ecosystems.
