Abstract

Anaerobic ammonium-oxidizing (anammox) bacteria have been detected in many marine and freshwater ecosystems. However, little is known about the distribution, diversity, and abundance of anammox bacteria in terrestrial ecosystems. In this study, anammox bacteria were found to be present in various agricultural soils collected from 32 different locations in China. Phylogenetic analysis of the 16S rRNA genes showed "Candidatus Brocadia," "Candidatus Kuenenia," "Candidatus Anammoxoglobus," and "Candidatus Jettenia" in the collected soils, with "Candidatus Brocadia" being the dominant genus. Quantitative PCR showed that the abundance of anammox bacteria ranged from 6.38×104±0.42×104 to 3.69×106±0.25×106 copies per gram of dry weight. Different levels of diversity, composition, and abundance of the anammox bacterialcommunities were observed, and redundancy analysis indicated that the soil organic content and the distribution of anammox communities were correlated in the soils examined. Furthermore, Pearson correlation analysis showed that the diversity of the anammox bacteria was positively correlated with the soil ammonium content and the organic content, while theanammox bacterial abundance was positively correlated with the soil ammonium content. These results demonstrate the broad distribution of diverse anammox bacteria and its correlation with the soil environmental conditions within an extensive range of Chinese agricultural soils. © 2013, American Society for Microbiology.
