摘要In marine ecosystems, both nitrite-reducing bacteria and anaerobic ammonium-oxidizing (anammox) bacteria, containing different types of NO-forming nitrite reductaseencoding genes, contribute to the nitrogen cycle. The objectives of study were to reveal the diversity, abundance, and distribution of NO-forming nitrite reductaseencoding genes in deep-sea subsurface environments. Results showed that higher diversity and abundance of nirS gene than nirK and Scalindua-nirS genes were evident in the sediments of the South China Sea (SCS), indicating bacteria containing nirS gene dominated the NO-forming nitrite-reducing microbial community in this ecosystem. Similar diversity and abundance distribution patterns of both nirS and Scalindua-nirS genes were detected in this study sites, but different from nirK gene. Further statistical analyses also showed both nirS and Scalindua-nirS genes respond similarly to environmental factors, but differed from nirK gene. These results suggest that bacteria containing nirS and Scalindua-nirS genes share similar niche in deep-sea subsurface sediments of the SCS, but differed from those containing nirK gene, indicating that community structures of nitrite-reducing bacteria are segregated by the functional modules (NirS vs. NirK) rather than the competing processes (anammox vs. classical denitrification).
