The bacteria in question in the study were found in the soil and were called madseniana. They relate to
Polycyclic Aromatic Carbon (PAH) -organic pollutant of soil and air. Studies of the effect of a substance on the human body have shown that it is carcinogenic - that is, it leads to the development of cancer.
During the study, scientists found thatmadseniana enters into symbiotic relationships with trees - they give carbon to bacteria, and they, in turn, decompose organic matter from the soil, releasing nutrients - such as nitrogen and phosphorus - to feed the trees.
While scientists do not know how bacteria can be used to control PAH soil pollution, further study of madseniana will help to find out.
Previously scientists discovered in Brazil, a new virus in which there are no previously known genes.
