Marine oil spill pollution was one of the factors affecting marine ecology northeastern South China Sea (nSCS). The submarine produced after had a long-term impact on microbial community in sediment. In this study, 16S rRNA genes high-throughput sequencing and quantitative PCR were used to study composition distribution bacterial communities deep-sea sediments; meanwhile, petroleum hydrocarbon ...
