the debate is over!? 26.8% of nitrogen in fleishmann's yeast is amino nitrogen.

I LOVE ancient studies!
All these other studies suggest something closer to 40-60% of the nitrogen is amino in yeast extract. That is significantly higher than the 26.8% number they got.

What ever the true number is, clear it is relatively low and large amounts of yeast must be used to provide enough nutrient for an active fermentation.

If someone can help identify a cheap lab, I'm ready to send some samples. Anyone here need a science project for school?
 
My GF is in organic chemistry class now, and taking part two next semester. I already asked her if she could determine such things, and I was laughed at, out loud, a few hours ago. I bet one of her TA's might be interested though, if there was money involved.
 
Medsen, remember in that study they said 68% were "undeterminable"... so the results of the ancient vs modern are not necessarily contradictory.
 
If Oskaar doesn't chime in soon, I'm going to throw a pillowcase of kittens into the Oconee River.
