Effects of oil contamination on microbial diversity in sediments from the southern Bohai Sea
Marine oil pollution is one of the main factors affecting the marine ecology of China's Bohai Sea waters. The leaked oil affects the community structure of microorganisms in offshore sediments to a certain extent. In this study, high-throughput sequencing of 16S rRNA gene and quantitative PCR were used to study the composition and distribution of bacterial communities in offshore sediments from three different stations in Laizhou Bay of the Bohai Sea, as well as the structural composition and distribution of microbial communities in surface sediments far and near to the estuary of the Yellow River, and at the same time, petroleum hydrocarbon-degrading bacteria were isolated and tested for their characteristics.
