Abstract: Crude oil pollution of water bodies poses significant environmental challenges, requiring innovative approaches for effective remediation. This study explored the bioremediation potential of the halotolerant cyanobacterium Oscillatoria sp. in addressing crude oil contamination in water systems. Halotolerant strains of Oscillatoria sp. were isolated and identified from a saline environment exposed to crude oil pollution. Laboratory-scale experiments were conducted to assess the ability of Oscillatoria sp. to degrade crude oil compounds and restore water quality. Biodegradation efficacy was evaluated by monitoring changes in crude oil composition and water parameters, including turbidity, pH, and hydrocarbon content. Results demonstrated that halotolerant Oscillatoria sp. exhibited notable capabilities for degrading various crude oil constituents. Over the experimental period, a substantial reduction in hydrocarbon content by the isolate supplemented with NPK from 8.992 mg/l to 1.486mg/l was observed while reduction from 8.992 mg/l to 7.272 mg/l was observed with isolate not supplemented with NPK. Thus, Oscillatoria sp with NPK recorded the highest degradation rate with a percentage remediation of 83.5%. Additionally, the water quality parameters improved, indicating the cyanobacterium's potential to enhance water clarity and reduce environmental stress caused by crude oil contamination. The bioremediation potential of halotolerant Oscillatoria sp. offers a promising avenue for sustainable water pollution mitigation. The ability of this cyanobacterium to adapt to saline conditions while efficiently degrading crude oil compounds enhances its utility in remediating contaminated water bodies.
