The technology is based upon the application of natural psychrophiles (low-temperature bacteria) that use hydrocarbons as their feed source and is designed to clean the coastline and waters of the northern seas of oil pollution. The innovative biological preparation was developed in stages.
At 1st, scientists established around 100 bacteria capable of decomposing oil and petroleum products at low temperatures, including those below zero. Over 250 samples of water were taken from major Northern ports and the coastline of Northern cities, such as Murmansk, Vladivostok etc.
For a number of strains, the hydrocarbon consumption rate was more than 70% in 14 days of the experiment. All microorganisms are endemic microflora of the northern seas, so their use is environmentally safe.
At stage 2, biologists launched the development of a hydrophobic shell that would accommodate the bacteria-based preparation. The hydrophobic shell dissolves at contact with hydrocarbon fraction alone, thus securing the target delivery of the preparation to the contaminated area and increasing its efficiency.
The preparation has already showed success in lab trials. Field trials of the product are scheduled at the Laboratory for Flow-Through Marine Systems at the Pertsov Belomorskaya Biological Research Station of the MSU. The Laboratory’s building is being upgraded with the support of Rosneft. Flow-through sea life aquariums allow testing the new product with no impact on the Arctic ecosystem and confirming its high potency and safety for use in-situ.
High standards of environmental safety are one of the cornerstones of the Rosneft-2022 Strategy. Environment protection is an integral part of the company’s corporate culture and social responsibility. At every of its business, Rosneft pays special attention to securing the environment, protecting and restoring natural resources.
