> > >Should I heat or chemically kill the yeast? Good question. Live yeast is easy to spot under a scope in the bee gut. It may also cause dysentery. But I have no idea as to whether your brewers yeast will do so. Heating to 72C would likely kill it. Easy to test by adding it to sugar water and seeing whether it ferments. -- Randy Oliver Grass Valley, CA www.ScientificBeekeeping.com *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
