In this study, the coast of Lebanon was analyzed for the dynamic changes in sediment microbial communities in response to a major petroleum oil spill and tar contamination that occurred in the summer of 2021. Spatio-temporal variations in the microbial structure along the shores of Lebanon were assessed in comparison to baseline microbial structure determined in 2017. Microbial community structure and diversity were determined using Illumina MiSeq technology and DADA2 pipeline. The results show a significant diversity of microbial populations along the Lebanese shore, and a significant change in the sediment microbial structure within four years. Namely, Woeseia, Blastopirellula, and Muriicola were identified in sediment samples collected in year 2017, while a higher microbial diversity was observed in 2021 with Woeseia, Halogranum, Bacillus, and Vibrio prevailing in beach sediments. In addition, the results demonstrate a significant correlation between certain hydrocarbon degraders, such as Marinobacter and Vibrio, and measured hydrocarbon concentrations.
在这项研究中，分析了黎巴嫩海岸的沉积物微生物群落的动态变化，以响应 2021 年夏季发生的一次重大石油泄漏和焦油污染事件。与 2017 年确定的基线微生物结构相比，评估了黎巴嫩海岸沿线微生物结构的时空变化。使用 Illumina MiSeq 技术和 DADA2 管道确定了微生物群落结构和多样性。结果表明，黎巴嫩海岸的微生物种群具有显著的多样性，并且在四年内沉积物微生物结构发生了显著变化。即，2017 年采集的沉积物样本中鉴定出了 Woeseia、Blastopirellula 和 Muriicola，而 2021 年观察到了更高的微生物多样性，海滩沉积物中占优势的是 Woeseia、Halogranum、芽孢杆菌和弧菌。此外，结果表明，某些碳氢化合物降解菌（如 Marinobacter 和 Vibrio）与测量的碳氢化合物浓度之间存在显著相关性。
