AB  - The accumulation of toxic inorganic nitrogen is one of the major water quality 
      problems in intensive aquaculture systems, thus the N removal in aquaculture 
      systems is an important issue for the sustainable development of aquaculture. To 
      understand one of the major microbial N removal processes, anaerobic ammonium 
      oxidation (anammox), phylogenetic diversity, and distribution of anammox bacteria 
      in sediments of four different marine aquaculture zones in Hong Kong (HK) were 
      investigated. The 16S rRNA genes analysis indicated that sequences detected from 
      Cheung Sha Wan (CSW) and Sok Kwu Wan (SKW) were closely related to several 
      clusters within the Scalindua genus of anammox bacteria, including a new 
      habitat-specific group, while only several sequences related to Scalindua and 
      Kuenenia were detected in Sham Wan (SW) and Yim Tin Tsai East (YTTE). Most of the 
      sequences obtained in SW and YTTE with the same PCR primers showed a low 
      similarity to the known anammox bacteria, forming several novel groups within the 
      Planctomycetes. However, results from the hydrazine oxidoreductase (HZO) encoding 
      gene showed that only sequences from SW were related to the genus of Kuenenia, 
      and sequences from other three sites were closely related to the genus of 
      Scalindua. The community analysis showed that CSW and SKW share similar anammox 
      bacterial community structures while SW and YTTE contain a unique anammox 
      bacterial community. Furthermore, correlations reflect that organic matter is 
      positively correlated with Kuenenia-like anammox bacteria, while the redox 
      potential is significantly correlated with Scalindua-like anammox bacteria in 
      marine aquaculture zones. Our results extend the knowledge of anammox bacteria in 
      marine aquaculture systems and highlight the importance of environmental factors 
      in shaping the community structures of anammox bacteria.
