Here's the only message of that type that I remember. It seems to be
specific for fungal contamination. As an alternative, you might try the
one-day streak technique, top of p. 48 in the Chlamydomonas Sourcebook.
This usually works for me.
For bacteria, I usually use the same streak-out technique rather than
antibiotics, but I've noticed that most other people around here go for
antibiotics instead. The best ones are generally ampicillin, tetracycline,
or chloramphenicol (which Chlamy will tolerate in remarkably high
concentrations on plates).
