Combustion of fores biomass generates dangerous contaminants including polycyclic aromatic hydrocarbons (PAHs). Thus, removal of these compounds is a pre-requisite to accelerate environmental restoration of fire-affected areas. Here, two different bioremediation strategies, namely soil bioaugmentation by means of the addition of a mycelial suspension of a Trichoderma sp. strain and soil biostimulation through the dispersion of a commercial landfarming formulation to enhance the native hydrocarbonoclastic microbial community by simply adjusting soil nutrients, were compared to verify the biotreatability of wildfire-generated toxic hydrocarbons (BTEX, LMW PAHs and C12-40 hydrocarbon fraction).
