Combined Use of Microbiodestructors and Humic Preparations for the Restoration of Gray Forest Soil Contaminated with Diesel Fuel

The results of experimental studies assessing the effectiveness of the combined use of biological preparations-oil destructors ("Glaukoil" and "MD") and humic preparations ("Gumi" and "Ecorost") for the bioremediation of gray forest soil contaminated with diesel fuel are presented. It has been established that in the presence of humic preparations the efficiency of microbiodestructors increases significantly. It is noted that the most effective is the combination of the biopreparation "MD" with the humic preparation "Ekorost". It is concluded that this approach allows not only to significantly reduce the concentration of diesel fuel in the soil, but also to partially neutralize the toxic effect of the pollutant in relation to soil microbiota, which is expressed in an increase in the activity of cellulolysis and proteolysis.
