[exudates]
I noticed "exudes" in the Actinovate documentation, but I would
think that would be a verb. "exudates" are what are "exuded"
by some organism.
Exotic words are a good excuse to find a free online dictionary,
like
http://dictionary.reference.com/
(which reports "no results found" for "exudate", then lists
it in both dictionary and reference text lists below that,
and clicking on the "exudate" in the dictionary list pulls
up a few dictionary definitions.)
