I heard that there are so many conditions neccesary for us who are living on the Earth.
Surely somebody must have collected them before. But I have a suggestion. What if PF people collect them once again in this thread?

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
