Answer:
That is a very complicated questions because bioremediation has so many different meaning.
For example, BioWorld Hydrocarbon Treatment is a form of bioremediation. They add microbes to an oil spill along with an enhancer to speed up the cleaning process.
Some companies just add microbes and call that bioremediation, some just add a fertilizer (which can cause algae to bloom, which isn't good).
So I would look up BioWorld's Hydrocarbon treatment! Look up their website.
