Excerpts;

Using advanced genomic identification techniques, researchers studying the impact of the Deepwater Horizon spill on communities of beach microbes saw a succession of organisms and identified population changes in specific organisms that marked the progress of the oil’s breakdown.

When oil from the Deepwater Horizon spill first began washing ashore on Pensacola Municipal Beach in June 2010, populations of sensitive microorganisms, including those that capture sunlight or fix nitrogen from the air, began to decline. At the same time, organisms able to digest light components of the oil began to multiply, starting the process of converting the pollutant to carbon dioxide and biomass…
