According to a statement issued by Oregon State University, USA, scientists from the university and the Chinese University of Science and Technology in Xi'an and Nanjing Agricultural University jointly studied and found a kind of bacteria that can help remove oil from the Gulf of Mexico.
In a statement, Oregon State University stated that the bacteria named "NY3" has "extraordinary ability" to produce rhamnolipids. Rhamnolipid is an anionic surfactant that does not pose a hazard to microorganisms, animals and humans, but it can degrade polycyclic aromatic hydrocarbons (PAHs) released in oil spill accidents similar to those in the Gulf of Mexico. Compounds are a special case of aromatic hydrocarbons that can cause cancer or induce genetic mutations.
The statement also stated that the rhamnolipids produced by NY3 are relatively stable in different temperatures, pH, and salinity environments and can effectively degrade at least 5 polycyclic aromatic hydrocarbons in crude oil.
A participating scientist said: "In the leaked crude oil, some of the most toxic substances to fish, wildlife and humans come from polycyclic aromatic hydrocarbons that can induce cancer, destroy the immune system, and trigger reproductive systems. Lesions and damage to the nervous system."
Oregon State University also stated that research on the safe and effective method of removing environmental pollutants has played an important role in the discovery of such biosurfactants and PAHs degrading microorganisms.
Currently, Oregon State University is applying for the above-mentioned US-China cooperation research results.
