I've read (in "Energetics and Transport in Aquatic Plants" by John Raven)
that this is true.  He reports studies that some species of algae can live
without light in glucose solutions and that most types of algae can
utilize labile organics as an energy source.  There are even some algae
called leucophytes that have lost their photosynthetic capabilities (I
guess they must still have their chloroplasts) and live entirely on
organic energy sources.

I don't know if EDTA could be used as an energy source.
