ABSTRACT
This study investigates the potential of Panicum maximum-derived compost and whey in the bioremediation of crude oil-contaminated soil. Compost and whey were prepared from Panicum maximum leaves and analyzed through quantitative and qualitative microbial assessments. A comparative study was conducted to determine which sample is more effective in soil remediation. Microbial analysis revealed that at a dilution factor of 10⁻¹, whey had a microbial count of 820 cfu/ml, while Panicum maximum compost (PMC) had 791 cfu/ml. However, at higher dilutions (10⁻³ to 10⁻⁵), PMC exhibited higher microbial counts, suggesting a greater potential for bioremediation. The presence of key microbial species, including E. coli, Salmonella, Bacillus, and Shigella, further highlights the biological activity within the samples. From the results obtained, Panicum maximum compost is more effective in soil remediation due to its superior microbial composition and degradation capabilities.
