Dry Baker's yeast as yeast nutrient

[brewmaster 2011]

there has been alot of talk about useing yeast as a yeast nutient. has anyone ever thought about useing dry backers yeast instead of brewers left over yeast slurrie?

It would make an interesting study- essentially your turning your yeast into cannibals and providing them with lipids and other nutrients. I think you would re-hydrate and them kill them first? Although most breweries have plenty of extra yeast on hand, so I don't see why you would buy more. Perhaps if you got better results this way.

Bingo. Or because there's plenty of FAN in an all-malt wort I just add 20 cents of zinc sulphate heptahydrate.
