Hydrocarbon contamination is one of the main causes of infertility in areas, leaving very critical levels for the ecosystem, reaching the point of being considered as one of the most concurrent problems due to the uncontrolled management of these by the industrial and productive sector. That is why new strategies have been formulated as a more reliable alternative in situations of response to hydrocarbon spills, with bioremediation with fungi and bacteria being the most efficient strategy. That is why this study aimed to determine the bioremediation effect of filamentous fungi (Aspergillus, Penicillium, Geotrichum, and, Rhizopus) in soil contaminated with 90 octane gasoline (Petroil Gasolina Premium). For this study, 6 kg of soil contaminated with 50 mL, 150 mL and 300 mL of 90 octane gasoline was used, along with four treatments X1 (Penicillium, Geotrichum, and, Rhizopus), X2 (Aspergill...
