Our microbiology dept. uses them in cronic pass/fail testing for 
industrial effluents. Ours are ordered from the EPA. They are 
extremely difficult to keep, even under laboratory conditions. They 
also have a short (< 30 days) lifespan and eat only certain strains 
of algae. Sorry, don't know of any feasible sources.
