Microorganisms are set on struggle with black oil, but not earlier than spring


Moscow, November, 15th.



Scientists of the Russian Academy of Science are measured to start "thin clearing" of zone of Kerch strait in the spring, informs ITAR-TASS. There will be used basically domestic biological products for petro oxidizing.


As the expert of the Russian Academy of Science has informed, the absorbing granulated or film preparations are applied to increase efficiency of mechanical removal of oil and water-black oil emulsion. However after their application there is a problem in future - recycling of the sorbents containing oil and most of them contain poisonous components.


According to the expert, “for starting of natural process of auto purification of an environment it is necessary to bring specially picked up active cultures or associations of petro oxidizing microorganisms, such, as developed by Institute of microbiology and patented in the Russian Federation preparation “Devoroil”.


These preparations work most effectively only at temperatures above +15, therefore " start the massed operation on thin clearing of water area of Kerch strait will be possible only in spring when the daily average temperature will come nearer to this parameter ", - the expert has informed.


Let us remind, that as a result of a gale and heavy sea on Sunday, on November, 11th is 4 vessels - dry-cargo ships "Vol’nogorsk", "Nakhichevan", "Kovel’" and Georgian "Hach Izmail" have sunk; one more barge - "Don-2" has sunk on November, 12th. 6 ships - dry-cargo ships "Vera Voloshinskaya" (Ukraine), "Ziya Kos" (Turkey), "Captain Izmail" (Turkey), barges "Dika", "Dimetra", lifting sea crane "Sevastopolets" were broke from anchors and have sat down on a bank; 2 tankers have received damages - "Volganeft’-139", "Volganeft’-123"; There is in drift barge "BT-3754".
