This study evaluated and compared the biodegradation performance of synthesised magnesium oxide nanoparticles and prepared Mangifera indica for breaking down total petroleum hydrocarbons in crude oil contaminated soil. The nanoparticles were produced from magnesium chloride and sodium hydroxide, while Mangifera indica material was cleaned, dried, and ground into powder. Soil properties were analysed before and after crude oil contamination across treatment weights of 5g, 25g, 50g, 75g, and 100g, alongside a control. Both treatments encouraged positive microbial growth linked to hydrocarbon breakdown. Over the tested weights, total petroleum hydrocarbon degradation reached between 72.65 percent and 93.45 percent for the nanoparticle treatments, and between 70.43 percent and 93.61 percent for the Mangifera indica treatments. Additionally, reaction kinetics were determined using the Michaelis Menten equation and Lineweaver Burk plots.
Crude oil spills severely damage soil health and ecosystems. Finding effective, alternative materials to clean up polluted soil is vital for environmental restoration. Demonstrating that plant-derived Mangifera indica achieves comparable hydrocarbon removal to manufactured magnesium oxide nanoparticles shows potential for using accessible organic materials alongside engineered nanomaterials to support microbial degradation in contaminated ground.
The findings could support soil remediation service providers and environmental management teams seeking treatments for crude oil spills. The study demonstrates applied laboratory testing using batch weights up to 100g, showing high degradation rates for both materials. However, moving toward commercial use would require validation at field scale, process standardisation, and formal cost comparisons between manufactured nanoparticles and processed agricultural materials.

The research study focused on the evaluation and comparison of bio-degradation efficacy of nanoparticle and mangifera indica for total petroleum hydrocarbon degradation in crude oil contaminated soil. Nanoparticle was achieved by reacting magnesium chloride with sodium hydroxide and the produced nanoparticle (magnesium oxide) was dried and ground to powdered form, while mangifera indica was concentrated via the removal of dirt’s and impurities, sun and air oven dried for complete moisture removal before its mechanical grinding and sieve to desired micron. The effects of nanoparticle and mangifera indica on total petroleum hydrocarbons bio degradation process were studied by characterization of the parametric properties of the soil prior and after contaminations with crude petroleum. The microbial growth rate responsible for the bio degradation of total petroleum hydrocarbons with nanoparticle and mangifera indica yielded a positive trend across the treatment variations for the control, 5g, 25g, 50g, 75g, and 100g samples respectively. The TPH percentage degradation in polluted soil for nanoparticle treatment ranges between 72.65%, and 93.45% for specific treatment weight, while the TPH percentage degradation for contaminated soil using the mangifera indica treatment yielded between 70.43%, and 93.61% for different weight samples respectively. Also, kinetic parameters of the Michaelis Menten equation for nanoparticle and mangifera indica were deduced for different samples using the Line-Weaver Burke plot.
