AbstractAnaerobic ammonium oxidizing (anammox) bacterial community structures were investigated in surface (1-2 cm) and lower (20-21 cm) layers of mangrove sediments at sites located immediately to the mangrove trees (S0), 10 m (S1) and 1000 m (S2) away from mangrove trees in a polluted area of the Pearl River Delta. At S0, both 16S rRNA and hydrazine oxidoreductase (HZO) encoding genes of anammox bacteria showed high diversity in lower layer sediments, but they were not detectable in lower layer sediments in mangrove forest. S1 and S2 shared similar anammox bacteria communities in both surface and lower layers, which were quite different from that of S0. At all three locations, higher richness of anammox bacteria was detected in the surface layer than the lower layer; 16S rRNA genes revealed anammox bacteria were composed by four phylogenetic clusters affiliated with the "Scalindua" genus, and one group related to the potential anammox bacteria; while the hzo genes showed that in addition to sequences related to the "Scalindua", sequences affiliated with genera of "Kuenenia", "Brocadia", and "Jettenia" were also detected in mangrove sediments. Furthermore, hzo gene abundances decreased from 36.5 × 10 4 to 11.0 × 10 4 copies/gram dry sediment in lower layer sediments while increased from below detection limit to 31.5 × 10 4 copies/gram dry sediment in lower layer sediments from S0 to S2. The results indicated that anammox bacteria communities might be strongly influenced by mangrove trees. In addition, the correlation analysis showed the redox potential and the molar ratio of ammonium to nitrite in sediments might be important factors affecting the diversity and distribution of anammox bacteria in mangrove sediments. © 2011 The Author(s).
