Potential of Trichoderma spp. strains for the bioremediation of soils contaminated with petroleum
Journal Title: Biotecnología Vegetal - Year 2016, Vol 16, Issue 4
Abstract
Fungi species can degrade xenobiotic compounds contaminating the soil, including hydrocarbons. The objective of this work was to determine the potential of three strains of Trichoderma, isolated from soil contaminated with petroleum, for bioremediation. Trichoderma harzianum CCECH-Te1, Trichoderma viride CCECH-Te2 and Trichoderma psedokoningii CCECH-Te3 were included in one assay with each independent strain. The inoculum was adjusted to a concentration of 1x10 10 conidia ml -1 which was applied to soil contaminated by an oil spill. After 96 days of inoculation, soil samples were taken at 10 and 15 cm depth. The content of total hydrocarbons, polycyclic aromatic hydrocarbons and heavy metals such as cadmium, nickel and lead were determined. With the data, it was calculated the percentage of removal of the analyzed compounds by each strain. At 10 cm and 15 cm depth, it was observed the removal of the compounds in percentages that reached between 47 and 69.1% in the hydrocarbons and up to 53.72% in the heavy metals. It which denoted the potential of the three strains for bioremediation in contaminated soils.
