Subject: What do the organisms used in oil spills do?

I am doing a project on how one would go about finding a way to clean up an oil spill. During my research I found that the spills are sometimes treated with the aid of tiny organisms. I have however been unable to find two things relating to this: 1. How did they discover that these organisms could clean up oil spills, or what test might they have done. 2. How are these organisms used all i read was that a colony is releashed and .... but is there any specific stratigy. All I have found is spill history or spill clean up agencies. thank you
