algae pigment extraction

Dear Folks,
I thought I remembered the posting of a simple protocol for the extraction
and comparison of pigments from red, brown and green algae in this venue
some time ago.  However, my search of the archives turned up nothing, so
I'll just ask:

Does anyone have a simple procedure for students that lets them extract and
compare the different pigments from the major groups of algae?

Secondly, I'm trying to think how to impress on my students that the first
type of photosynthesis to evolve did not produce oxygen.  Is there a
non-oxygenic but photosynthetic bacterium out there that that one could use
in a lab exercise to show students there are others ways of doing
photosynthesis?  I'm totally ignorant here and at your mercy.
