| Popis: | Investigated data about the selection of the effective microorganisms – oil destructors from the environmental objects and industrial waste. Founded the most active bacterial strains were isolated from the Caspian Sea bottom sediments. Hydrophobicity’s index and emulsifying activity of the most active oil bacterial destructors were defined. Their efficient use of oil or diesel fuel as the only carbon’s source was shown. The growth dynamics of these strains on nutrient containing oil media was studied. Shown the bacterial strain VGTU-02 possessed the greatest speed of growth and destructive activity concerning oil hydrocarbons. Studied the possibility of the using some crop waste and carbonizate from spent activated sludge as a matrix for biosorbents. The microbial base for these biosorbents was the bacterial strain VGTU-02. Selected microorganisms were attached to the studied carriers from the crop waste and waste activated sludge. Efficiency of purification of model liquid from crude oil at use of the suspended VGTU-02 microorganisms with matrixes was defined. Shown that under similar conditions, the highest efficiency of oil purification was achieved 99.41 % for a matrix based on sunflower husk and 98.46% based on carbonizate. The developed biosorbents can be used to remove oil and petroleum products from wastewater. |
