Scientists of Perm National Research Polytechnic University (PNIPU) discovered new microorganisms that can effectively clean the soil of oil pollution. This was reported to the “Gazeta.ru” in the press service of the scientific institution.
Petroleum products are one of the most dangerous technological waste that has a long negative effect on ecosystems. Traditional purification methods such as combustion or use of chemical reagents are generally ineffective and harmful to nature.
PNIP researchers have allocated two new bacterial strains from contaminated soil samples with petroleum products. Birth arthrobacter and pseudomonas -related microorganisms can use hydrocarbons as a power supply, destroy them, and reduce the concentration of toxic substances in the soil. During the experiments, scientists examined the effect of the temperature and concentration of hydrocarbons on the effectiveness of cleaning.
“The biggest event was shown by the number 11 culture, which reduced the content of petroleum products in the soil by 60%within two weeks. This makes it promising for use in biomedic, Gal says Galina Kozlova, the assistant assistant assistant of the “Chemistry and Biotechnology” section.
The study also showed that the optimum temperature for the operation of bacteria was 20 ° C. With lower values, the cleaning process slows down. Scientists plan to continue to examine new strains and develop biological products according to their foundations to clean the dirty areas.
