Bacterial Communities and Culturable Petroleum Hydrocarbon Degrading Bacteria in Marine Sediments in the Northeastern South China Sea

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 degrading bacteria isolated, which activity detected. Proteobacteria Planctomycetota main phyla found samples studied study. 29 strains capable hydrocarbons isolated from S02 S39 sediment samples, belonging genus Stenotrophomonas , Pseudidiomarina Sulfitobacter Pseudomonas Halomonas so on. Strains degraded efficiently. This research provided new insights into pattern benthic nSCS, validated degradation potential by indigenous bacteria.
