Compositions for the bioremediation of soils contaminated with hydrocarbons and/or solvents and/or organic compounds

摘要

The present invention relates to a composition for the bioremediation of soils contaminated with hydrocarbons and/or solvents and/or organic compounds comprising: a) a compost derived from plant lignocellulosic materials, biological sludges, the organic fractions from solid urban wastes, animal manure or mixtures thereof and having a respiration index between 500 and 1000; and b) a consortium of bacteria and/or moulds adapted and/or induced to metabolise the particular contaminant(s) which one desires to remove from the soil; wherein the amount of said micro organisms per m<3> of said composition corresponds to that present in a volume comprised between 1000 and 5000 ml of a culture broth containing between 20 and 40 g of wet biomass/litre. The present invention refers in addition to a procedure for the bioremediation of contaminated soils through the use of the above composition.
