| 英文摘要 | Nitrogen cycle is critical to maintain a healthy coral reef ecosystem. Urea can provide a source of nitrogen for coral holobiont and is important for coral calcification through degradation by urease. Despite the involvement of coral-associated bacteria in nitrogen fixation, nitrification and denitrification are well recognized, to what extend urea degradation by bacteria contributing to the urea utilization by coral holobiont remains to be investigated. In this study, we demonstrate that the urea utilization is a common feature ofHalomonasspp. that is a dominant genus in cultivable coral-associated bacteria. A urease operon was characterized by genome sequencing and gene knock-out technique inHalomonas meridianaSCSIO 43005, isolated from the gastric cavity of healthy scleractinian coralGalaxea fascicularis.H. meridianashowed high urease activity which was induced by urea and deletion of the urease operon reduced the capability to use urea as solo nitrogen source. Furthermore, approximately 1/3 coral-associated bacteria in the IMG/M database possess complete urease operons indicating the involvement of bacteria-derived ureases in coral holobiont. These results suggest that urease from coral-associated bacteria might be important player in the nitrogen cycling of coral reefs. |
