@deltaalpha21074 Ethanol enzymes are 1. Alpha-amylas enzyme It is added wen mash cools to 194-203 degrees. 2. Gluco-amylase enzyme add at 136-144 degrees. both are found on the internet at Mile Hi Distilling. i think. those enzymes should brake the corn down into simple sugars that yeast like.

I make my own e85 at home and run my 2001 Caddy DeVille on it; its not hard and it is legal to make here in the US just get a free permit from the BATF & you can produce 10,000 gallons a year! Check out my site MyCarIsDrunk. com for more info

But the industry is going to keep this a secret. They will just tell you Corn make Ethanol. Good for Profit.

Enzymes aren’t microoorganisms, they are biomolecules. The yeast cells use enzymes to convert sugars to the alcohol product using their own enzyme catalyzed pathway called fermentation. Ethanol and water are the toxic biproducts of this bioprocess. Ethanol can then be separated from water by simple distillation.
