In recent years, EPS sugars from marine bacteria have been found to speed up the cleanup of oil spills. During the Deepwater Horizon oil spill in 2010, these EPS-producing bacteria were able to grow and multiply rapidly. It was later found that their EPS sugars dissolved the oil and formed oil aggregates on the ocean surface, which sped up the cleaning process. These oil aggregates also provided a valuable source of nutrients for other marine microbial communities. This let scientists modify and optimize the use of EPS sugars to clean up oil spills.
