An Illumina-based next-generation sequencing was employed to characterise the sediment microbiome adjacent to coastal industrial and tourist cities, Taizhou and Xiamen, in China, and their associations with chemical pollution were explored. The results indicated that chemical pollution of sediments from Taizhou was higher than that from Xiamen. The number of sediment bacterial genera was negatively (Taizhou) or positively (Xiamen) correlated with offshore distance, owing to shifts in the primary and secondary status of organic matter and chemical pollutants for the promotion or inhibition of the sediment microbiome. The total number of the operational taxonomic units (OTUs) in sediments from Taizhou was larger than from Xiamen, while the number of core OTUs was smaller indicating that Taizhou had more impact on core microbes in sediments than Xiamen. This study suggests that chemical pollutants and organic matter result in different co-regulation of the off-shore sediment microbiome of coastal industrial and tourist cities.
采用基于 Illumina 的新一代测序技术，对中国沿海工业和旅游城市台州和厦门的近海沉积物微生物组进行了特征描述，并探讨了其与化学污染的关系。结果表明，台州沉积物的化学污染高于厦门。由于有机物和化学污染物的主次地位发生变化，促进或抑制了沉积物微生物组，台州的沉积物细菌属数量与离岸距离呈负相关（台州）或正相关（厦门）。台州沉积物的总操作分类单元（OTUs）数量大于厦门，而核心 OTUs 数量较小，表明台州对沉积物核心微生物的影响大于厦门。本研究表明，化学污染物和有机物导致沿海工业和旅游城市近海沉积物微生物组的不同协同调控。
