“…When agricultural hydrocarbon contaminated soils contain few nutrients, the biodegradation processes are significantly reduced because the plants require such elements for their development, above all for their radical system growth, the habitat where microorganisms transform the contaminants (Panwar, R., & Mathur, 2023). Therefore, incorporating essential nutrients in soil is necessary (Martínez et al, 2019).…”

Objective: The purpose of the present study is to highlight the importance of assessing bioremediation and total petroleum hydrocarbon removal by bioaugmentation and biostimulation on the rhizosphere. Design/methodology/approach: An 89-day experiment was established with treatments considering plant (corn) establishment–crude petroleum (25,000 mg kg-1)–bacteria and hydrocarbonoclastic fungi–adding nitrogen and phosphorus to agricultural soil. At the end of the experiment, hydrocarbonoclastic fungal and bacterial populations and total petroleum hydrocarbon removal were assessed. Results: Both microbial groups increased in number and time. The treatment with 120 kg nitrogen ha-1 and 12.5 kg phosphorus ha-1 allowed the highest population (227 x 103 g-1 of colony forming units (CFU) of hydrocarbonoclastic bacteria). A total of 83% petroleum hydrocarbon removal was obtained as established in 89 days. Limitations on study/implications: The effectiveness of bioremediation can vary significantly in real environments due to factors, such as soil variability, climate. Findings/conclusions: The previous results highlight the importance of using these bioremediation techniques to eliminate hydrocarbons in contaminated agricultural soils.
