Abstract: The method for preventing the formation of oil-win-water and/or water-in-oil emulsions and/or for breaking up emulsions already formed, comprises the steps of: (a) adding tensides, materials for increasing viscosity, industrial surfactants, and microorganisms capable of breaking down crude oil components or derivatives and producing at least one type of tenside, to the emulsion already formed or into the device containing the crude oil in which the formation of the emulsion to be prevented, optionally together with additives required for the reproduction of said microorganisms; (b) providing an appropriate temperature for the microorganisms after the addition of the materials listed above; (c) allowing the microorganisms to reproduce and act for a predetermined period of time; (d) checking the results of the treatment; and (e) optionally repeating steps (a) to (d) at least once more, preferably at least three more times.

Abstract: The method for the prevention, reduction and/or removal of asphaltene-paraffin-vax precipitates on surfaces in contact with crude oil within oil-wells from bottom hole to well head, in flow lines and pipelines by the use of biocolloid suspensions comprises the steps of: adding together (a) microorganism(s) capable of reacting with, solubilizing of and/or resistant to the components of crude oil, (b) organic or inorganic additives, or (c) a mixture thereof into the pipes; and allowing the so formed suspension containing the microorganisms to act for a desired time. The suspension is used for the decomposition, washing-off and removal of solid hydrocarbons and mixtures of long chain hydrocarbons, as well as for the prevention of formation thereof.

Abstract: The invention relates to methods for land improvement (soil reclamation), preferably for soil remediation comprising the steps of (i) placing a material useful for improving soil, and an explosive in the soil, and (ii) mixing the materials useful for reclaiming the soil and the polluted soil by explosion. The invention also relates to methods methods for providing microorganisms useful for decomposing hydrophobic pollutants, mineral oil components and derivatives by selection and isolation from soil, the microorganisms, their uses and kits for land improvement and soil remediation. The invention is useful in particular for remediation of soil polluted with oil components and derivatives.
