Purpose: Anammox bacteria have been widely investigated in both natural aquatic habitats and wastewater treatment reactors. However, their distribution in agricultural ecosystems which receive high reactive nitrogen input is hardly known. This study aims to examine the distribution and diversity of anammox bacteria in different Chinese paddy soils and along soil profile horizons. Materials and methods: DNA was extracted from paddy soils which were collected from ten sites and along four soil depth horizons (0–20, 20–40, 40–60, 60–80 cm). Community structure and diversity of the anammox bacteria were analyzed using cloning and sequencing methods by targeting 16S ribosomal RNA (rRNA) genes. Qu..View full abstract
