在生物氮循环中，亚硝酸盐的氧化是由亚硝酸盐氧化菌完成的，其中硝化螺菌属分布广泛，种类繁多。在南海25-1500 m深度采集了硝化螺菌群落。系统发育多样性，社区组成和环境因素进行了调查，使用高通量测序靶向nxrB基因和统计分析。硝化螺菌的群落组成在空间和深度上存在差异。在24个丰度相对较高的OTU中，70%未分类，不隶属于已知的Nitrospira属，这表明海洋Nitrospira具有以前未被认识的高多样性。共检测到5个已知的硝化螺属，其中常见的海洋硝化螺属（Nitrospira marina）不是优势种，而在浅水生境中以钝头硝化螺属（Acidatus Nitrospira lenta）和德氏硝化螺属（Acidatus Nitrospira defluvii）为优势种。硝化螺旋菌（Comammox nitrospira nitrosa）是在海洋生态系统中发现的一种微生物。多功能硝化螺菌的生态位分化主要受硝酸盐、温度和溶解氧的影响。在南海25-1500 m深度采集了硝化螺菌群落。硝化螺菌群落在浅海和深海之间的空间变化。在海洋生态系统中发现了硝化螺菌。硝酸盐、温度和溶解氧影响了硝化螺菌物种的生态位分化。生物地球化学;全球营养循环;微生物学;分子微生物学
In the biological nitrogen cycle, nitrite oxidation is performed by nitrite oxidation bacteria, of which Nitrospira is widespread and diverse. Communities of Nitrospira were collected at 25–1500 m depths in the South China Sea. Phylogenetic diversity, community composition, and environmental factors were investigated using high-throughput sequencing targeting the nxrB gene and statistical analyses. The community composition of Nitrospira varied spatially and by depth. Among the 24 OTUs with relatively high abundance, 70% were unclassified and not affiliated with the known Nitrospira genus, suggesting a previously unrecognized high diversity of marine Nitrospira. Five known Nitrospira genera were detected, of which the common marine Nitrospira marina was not the dominant species, whereas Candidatus Nitrospira lenta and Candidatus Nitrospira defluvii dominated in shallow habitats. Comammox Candidatus Nitrospira nitrosa was discovered in the marine ecosystem. The niche differentiation of versatile Nitrospira species was mainly shaped by nitrate, temperature, and DO.
