Beneficial to whom?  The organism or us?  What happened to those bacteria that used oil 
as an energy source of some sort...for example, they were supposed to be used to help 
clean up oil spills...perhaps those were created from non-oil metabolizing bacteria by 
some mutation...perhaps not.  Maybe someone knows for sure.  Ed.
