Remember the BP Deepwater Horizon oil catastrophe? The oil was eaten up by ocean microbes (because Mother Nature heals itself)

When the oil drilling rig, known as Deepwater Horizon, that was operating off the Gulf of Mexico around 40 miles from the Louisiana coast suddenly exploded and sank in April 2010, 11 people died and oil began to spill into the ocean a mile blow its surface. In just three months, the BP Deepwater Horizon fiasco saw 4.9 million barrels of oil spilling into the Gulf of Mexico. As the biggest oil spill in our nation’s history, it led to damages exceeding $17.2 billion.

The environmental effects were staggering, with as many as 80 million young fish believed to be killed, along with around a third of the worms and snails living near the well. Moreover, the spill resulted in the deaths of around 50,000 birds, 120 bottlenose dolphins, and 8,000 young sea turtles. While some of these species can be replenished in a decade or two, it will take around 300 years for the 120 deepwater corals that died to recover.

Despite widespread concern about whether it was even possible to clean up an oil spill of this magnitude, the oil somehow disappeared on its own. Scientists put forth a lot of theories, and new research has uncovered that oil-degrading bacteria deserve the credit for cleaning up the spill.

After a 64-day study in which researchers simulated the conditions of the spill and examined the oil degradation mechanisms of the main oil-degrading bacteria found in the actual spill, they found that tiny oil droplets kept a lot of the oil from making its way to the surface of the ocean. They said that microbes that occur naturally at the relevant depth are specialized in growing through the use of certain components of the oil as food. Essentially, their report says, the microbes managed to “chew up the oil.”

It is believed that the dispersants used on the spill broke the oil down into tiny droplets, making them less buoyant and preventing them from floating to the surface. This kept the oil in a cloud underneath the surface, where it was easier for the microbes to reach. The Candidatus Bermanella macondoprimitus bacterium played a big role in this action.

Could these findings help deal with future oil spills?
