The Deepwater Horizon oil spill was unique, according to the scientists, because it happened at such great depth and contained so much natural gas--predominantly methane, ethane, and propane.
In earlier studies, Valentine, Redmond and colleagues showed that ethane and propane were the major hydrocarbon compounds consumed in June 2010, two months after the April spill.
The methane, ethane and propane data, and new evidence from hydrocarbon and helium isotopes, all suggest that drilling has affected some homeowners' water,” said Robert B Jackson, a professor of environmental sciences at Duke's Nicholas School of the Environment.
In earlier studies, Valentine, Redmond, and their colleagues showed that ethane and propane were the major hydrocarbon compounds being consumed in June 2010, two months after the start of the April spill.
The ethane and propane data are“particularly interesting,” he noted,“since there is no biological source of ethane and propane in the region and Marcellus gas is high in both,and higher in concentration than Upper Devonian gases” found in formations overlying the Marcellus shale.
This suggests that the Colwellia were abundant because they grow well at low temperatures and because they could consume ethane and propane, which were very abundant during the spill, the researchers said.
The bacteria that consumed the ethane and propane were the same Colwellia that we saw at high abundance in the environmental samples from May and June,when ethane and propane consumption rates were high,and that were abundant when we incubated oil at 40 degrees, but not at room temperature.".
