DETOXIFYING ABILITY OF PEAT HUMIC ACIDS TO PETROLEUM PRODUCTS IN THE SOIL ECOSYSTEM

The stimulating effect of humic acids on the growth biomass test object was established. А series positive effects seedlings proposed. correlation dependence toxicants cockweed its composition revealed. It shown that light ends oil has a minimal toxic due to increased volatility, in contrast petroleum. detoxifying ability peat established separately and together with oil-degrading microorganisms genus Rhodococcus inert substrate by method biotesting. Humic had regardless their genesis. maximum exhibited isolated from fen peats. contaminated soil presence all variants experiments model higher compared variant without treatment acids. detoxification coefficients were calculated relation hexadecane: sphagnum high-moor transitional showed effect: 70−75%. Combined use Rh. erythropolis S67, X5 4−22%. values vary range 59−85%, depending genesis selected strain microorganisms. moil-degrading exceed indicators control experimental options using only produce biologically active surfactants capable more emulsification biodegradation hydrocarbons environment.
