Study on sedimental archaeal diversity and its correlation with environmental factors in Coastal Chemical Industry Park

  • Archaeal community plays an extremely important role in marine biosphere and affects the cycling of carbon, nitrogen, sulfur, iron, and other elements in marine ecosystems. There are a large number of archaea in marine sediments. The investigation on their distribution and diversity lays the basis of understanding their ecological functions. In this study, the sediments of Jiaojiang Chemical Industry Park of Zhejiang Province were sampled, and metagenomic analysis based on the Illumina Miseq PE300 high throughput sequencing platform was applied to investigate the Archaea community. A total of 52 genera, 37 families, and 11 phyla of Archaea were detected from the sediments. Thaumarchaeota was the most predominant phylum, accounting for 49% of the total abundance, followed by Crenarchaeota, Euryarchaeota, and Woesearchaeota. Nitrosopumilus was the most abundant group at genus level, accounting for 48% of the total abundance. Obvious spatial heterogeneity was found in marine sedimental environment in the study area, which might have an impact on the archaeal community structure. Cadmium, lead, arsenic, chromium, mercury and other heavy metals were significantly correlated with certain archaeal phyla.
