Bioremediation involves the use of microorganisms to degrade organic contaminants present in the environment, transforming them into simpler and less dangerous compounds, even innocuous ones. This decontamination investigation has a wide public acceptance and can be carried out on the site. Compared with other methods, bioremediation is a more promising way to eliminate contaminants present in soils and water, for this reason this project was implemented using this method. The general objective was: To determine to what extent the genera Penicillium spp, Phanerochaetes spp and Trychoderma spp can bioremediate soils contaminated with DDT in the city of Moyobamba. In this research three genera of fungi Penicillium, Phanerochaete and Trychoderma were evaluated, which had the role of bioremediating or reducing different amounts of organochlorine DDT, being this pesticide very persistent in the environment especially in the soil. The irrigation method was used to give comfort to each fungus genus according to their livelihood by adding water to maintain adequate moisture conditions for bioremediation on terrestrial surfaces as it is very common for them to lose moisture, which is why the application was every two days during the 13 weeks of observation, with a reduction of 40% at 45 days and 85% at 90 days according to the genera that most bioremediated. According to the results obtained in the first sampling at 45 days of evaluation, the optimal treatment was the Phanerochaete genus for the bioremediation of contaminated soils, which significantly reduces DDT, on the other hand in the second sampling at 90 days of evaluation the optimal treatment it was the genus Phanerochaete. Regarding the isolation of bacteria, strains of Penicillium, Phanerochaete and Trychoderma were identified. These genera have been identified in previous investigations as pesticide degraders and organochlorine compounds. Through the technique of direct observation with the help of the microscope, the morphological characteristics of each genus were recognized.
