US-China Collaboration to battle the oil spill
Researchers at the Oregon State University (OSU) claim today that they have discovered a new strain of bacteria, named "NY3”, which can help in the cleanup efforts, if not in stemming the flow of oil.
Discovery of NY3 is resulted from a collaboration between OSU and Xi'an University of Architecture and Technology and Nanjing Agricultural University.
NY3 has an "extraordinary capacity" to make rhamnolipids that is a biosurfactants and can be used to break down oil and degrade some of its most lethal compounds. br>
"PAHs are a widespread group of toxic, carcinogenic and mutagenic compounds, but also one of the biggest concerns about oil spills," Xihou Yin, a research assistant professor in the OSU College of Pharmacy, said.“This particular strain of bacteria appears to break up and degrade PAHs better than other approaches we have available,"
The challenge now is the cost of production and replacement of synthetic chemicals with NY3. “Strain NY3 has been optimized to produce a very high yield of 12 grams per liter, from initial production levels of 20 milligrams per liter," Yin said.
