EMULSIFYING ABILITY OF BIOCOMPOSITION BASED ON HUMIC SUBSTANCES AND MICROORGANISMS OF THE GENUS RHODOCOCCUS IN THE RELATION TO OIL

The stabilizing ability of humic substances of peats in the relation to oil has been studied. The maximum dispersion of oil drops was observed in the presence of Rhodococcus erythropolis X5 microorganisms and humic substances of sphagnum high-moor peat, as well as Rhodococcus erythropolis S67 microorganisms and humus substances of reed fen peat. Conducted assay proved that the reduction of the oil film can be used as a test to prove dispersing ability of microorganisms Rhodococcus X5 or S67 and humic substances. It was found that in the presence of humic substances oil emulsions stabilized in the best way, which is explained by the nature of the interaction of humic substances with the alkyl moieties only through hydrophobic interactions. It this study stability of aqueous emulsions of oil in the presence of microorganisms Rhodococcus erythropolis S67 and humic substances of reed fen peat was proved. The proposed dual systems based on humic substances of peats and microorganisms of the genus Rhodococcus were capable of stabilizing emulsions of oil-in-water hydrocarbons by binding them as non-toxic complexes with humic substances.
