Oil spillage incidents have significant consequences on the environment, human health, and the economy through contaminating water and soil, harming wildlife, and disrupting the ecosystem. Cleanup and restoration efforts are costly and time-consuming, and the economic impact can be significant for industries. Oil spills are a typical occurrence in Dhaka, the capital of Bangladesh, due to its high demand for this megacity among the filling stations. Unexpected spillages usually occur during the processing, transportation, storage, or consumption of oil. Bioremediation - the process of biodegradation employing indigenous microorganisms onto xenobiotic or recalcitrant substances - is considered an effective alternative to clean up oil spills. Because microorganisms can consume the oil as a food source and break it down into less or no harmful compounds. This method is more environmental-friendly, long-lasting, and cost-effective than the traditional cleanup method. However, a more robust and effective remediation process can be developed focusing on the genomic insights of the endemic and more metabolically advantageous microbial strains pertinent to the environmental pressure in Bangladesh. This study thus aims to explore the bioremediation potential of the indigenous bacterial strains with the support of whole-genome analysis.

溢油事件会通过污染水体与土壤、危害野生生物、破坏生态系统，对环境、人类健康及经济造成严重影响。溢油后的清理与修复工作往往耗时耗力，且对相关产业而言可能带来显著的经济损失。孟加拉国首都达卡作为特大城市，境内加油站燃油需求极高，因此溢油事件在当地颇为频发。意外溢油通常发生在石油的加工、运输、储存或使用环节。生物修复（bioremediation）——即利用本土微生物对外源性或难降解物质进行生物降解的过程——被认为是清理溢油的有效替代方案。这是因为微生物可将石油作为营养源加以消耗，并将其分解为低害甚至无害的化合物。相较于传统清理手段，该方法更具环境友好性、持久性与成本效益。然而，若结合孟加拉国本土环境压力下的特有且代谢优势更强的微生物菌株的基因组学特征，可开发出更为高效可靠的修复工艺。因此，本研究旨在借助全基因组分析技术，探究本土细菌菌株的生物修复潜力。
