[Effect of photosynthetic bacteria and compost on degradation of petroleum products in soil].

Addition of diesel fuel and waste engine oil to soil was found to cause biostimulation of hydrocarbon-oxidizing microorganisms. Corynebacteria constitute a large group of hydrocarbon-oxidizing microorganisms. Addition of a liquid culture of photosynthetic bacteria to soil not only facilitates degradation of petroleum products, but also stimulates growth of hydrocarbon-oxidizing microorganisms. Combined addition of photosynthetic bacteria and compost to soil polluted with petroleum products causes even a more significant increase in the count of hydrocarbon-oxidizing bacteria and substantially increases the rate of pollutant degradation.
