摘要

Cobamides are required by most organisms but are only produced by specific prokaryotic taxa.These commonly shared cofactors play significant roles in shaping the microbial community and ecosystem function.Wastewater treatment plants(WWTPs)are the world's most common biotechnological systems;knowledge about sharing of cobamides among microorganisms is predicted to be important to decipher the complex microbial relationships in these systems.Herein,we explored prokaryotic potential cobamide producers in global WWTP systems based on metagenomic analyses.A set of 8253 metagenome-assembled genomes(MAGs)were recovered and 1276(15.5%)of them were identified as cobamide producers,which could potentially be used for the practical biological manipulation of WWTP systems.Moreover,8090 of the total recovered MAGs(98.0%)contained at least one enzyme family dependent on cobamides,indicating the sharing of cobamides among microbial members in WWTP systems.Importantly,our results showed that the relative abundance and number of cobamide producers improved the complexity of microbial co-occurrence networks and most nitrogen,sulfur,and phosphorus cycling gene abundances,indicating the significance of cobamides in microbial ecology and their potential function in WWTP systems.These findings enhance the knowledge of cobamide producers and their functions in WWTP systems,which has important implications for improving the efficiency of microbial wastewater treatment processes.
