REPORT FROM THE RUSSIAN ACADEMY OF SCIENCE, ON PREPARATIONS USING PETROOXIDIZING MICROORGANISMS
Tests were made in April, May 2002 in a laboratory of oil microbiology of the microbiology Institute at the Russian Academy of Science. The soil for the tests was taken from an oil overflow place in Saratov city. The pollution degree is 157 g/kg. Age of pollution is 8 months. Before the tests the soil was carefully mixed, all foreign particles were removed. Soil ditches (600) have been processed twice (in two weeks) by the preparations and isolates of petrooxidizing microorganisms. Before processing by the biological products fertilizers (nitrophoska) were added, the soil was regularly humidified and stirred. The contents of the oil products were determined on concentration meter KN-2 (by the method of infra-red spectroscopy). The test results are in the below table.
