Potential of grasses and rhizosphere bacteria for bioremediation of diesel-contaminated soils Rev. Bras. Ciênc. Solo
Mezzari,Melissa Paola; Zimermann,Daniela Mara Hoffmann; Corseuil,Henry Xavier; Nogueira,Alexandre Verzani.
The techniques available for the remediation of environmental accidents involving petroleum hydrocarbons are generally high-cost solutions. A cheaper, practical and ecologically relevant alternative is the association of plants with microorganisms that contribute to the degradation and removal of hydrocarbons from the soil. The growth of three tropical grass species (Brachiaria brizantha, Brachiaria decumbens and Paspalum notatum) and the survival of root-associated bacterial communities was evaluated at different diesel oil concentrations. Seeds of three grass species were germinated in greenhouse and at different doses of diesel (0, 2.5, 5 and 10 g kg-1 soil). Plants were grown for 10 weeks with periodic assessment of germination, growth (fresh and dry...
