The abundance and diversity of anaerobic ammonium oxidation (anammox) bacteria were assessed in 152 groundwater samples in the Kathmandu Valley, Nepal. Anammox bacterial 16S rRNA genes were detected in 54% (37/68) of samples collected in the dry season at 1.6×10-8.8×10 copies L, and in 60% (50/84) of samples collected in the wet season at 4.3×10-1.2×10 copies L. The 16S rRNA genes of "Candidatus Brocadia", "Candidatus Anammoxoglobus", and five new deduced anammox bacterial phylotypes were detected in the shallow groundwater samples. Diverse anammox bacteria were broadly distributed in the shallow groundwater aquifer of the Kathmandu Valley.
在尼泊尔加德满都谷地的 152 个地下水样本中，评估了厌氧氨氧化（anammox）细菌的丰度和多样性。在旱季采集的 68 个样本中，有 54%（37/68）检测到了 anammox 细菌 16S rRNA 基因，浓度范围为 1.6×10-8.8×10 拷贝 L；在雨季采集的 84 个样本中，有 60%（50/84）检测到了 anammox 细菌 16S rRNA 基因，浓度范围为 4.3×10-1.2×10 拷贝 L。在浅层地下水样本中检测到了“Candidatus Brocadia”、“Candidatus Anammoxoglobus”和五个新推断的厌氧氨氧化细菌的 16S rRNA 基因。多种多样的厌氧氨氧化细菌广泛分布在加德满都谷地浅层地下水含水层中。
