S. cerevisiae secretes invertase (sucrose metabolism) at a high rate. You
can assay it many ways, even in a gel by running cell media.
You might also consider alpha-factor if you are interested in the non-
beaten-path. It's a small bioactive peptide. It is assayed by it's ability
to stop cell growth on a plate.
