Abstract Petroleum contaminants and fossil fuel activities contribute significantly to environmental pollution, especially in regions involved oil production. Polyaromatic hydrocarbons (PAHs) petroleum products are hazardous the environment human health because of their intricate chemical makeup cancer-causing characteristics. In this study, we isolated characterized bacterial strains from oil-contaminated soil using 16S rRNA analysis evaluate potential for degrading PAHs commonly found drilling wastes. We also analyzed PAH content cuttings assessed effectiveness biodegradation by consortium on real oil-drilled cutting samples. Additionally, a bioremediation comprising Pseudomonas stutzeri, aeruginosa, Bacillus subtilis was used remediate PAHs. This study suggests that indigenous bacteria favorably process biodegradation. observed benzo(a)anthracene exhibited fastest degradation rate among tested compounds, while fluorene showed slower than other compounds. Importantly, efficiency all scenarios surpassed 97%, highlighting efficacy approach reducing contamination. These results underscore utilizing consortia effective remediation, contributing development sustainable strategies remediation.

The growing global emphasis on sustainable agriculture has brought increased attention to the health and productivity of soils, especially through lens soil microbiology. Microbial communities in are essential for nutrient cycling, organic matter decomposition, maintaining overall health. However, agricultural practices, including synthetic fertilizers intensive farming, have led short time impacts these microbial ecosystems, potentially threatening fertility environmental quality. Agricultural expansion food production generate waste chemical inputs, such as heavy metals, pesticides, herbicides, leading significant contamination. This scenario requires implementation remediation strategies that both energy efficient. In this context, microbiological processes present a much promising approach mitigating pollution. Techniques bioremediation, which harness natural metabolic capabilities microorganisms, bioaugmentation, involves introduction specific strains increase degradation processes, being explored. These approaches vital restoring health, contributing conservation biodiversity, improving promoting long-term productivity.
