Bacteria to purify the Arctic water

28 march 2023
Russian scientists have developed a preparation based on microorganisms to purify the Arctic waters. According to the Russian newspaper AiF, the research was carried out with the participation of Rosneft and Innopraktika on the basis of the biological station of Moscow State University.
Ships and ports pollute Arctic waters with hydrocarbons. To minimize damage and restore the environment, scientists propose using a preparation that contains bacteria that feed on hydrocarbon waste.
“The form of the preparation is unique, since it involves the activation of microorganisms directly in the contaminated area. The composition of the preparation contains psychrophilic (that is, adapted to a cold climate) microorganisms. They make the preparation effective in the Arctic seas, where the water temperature is often negative,” the scientists said.
Researchers will continue to study the impact of human activities and climate change on the ecosystems of the Arctic seas. The focus of their work will be the White Sea, where scientists intend to conduct research with the support of Rosneft.
