I apologize in advance if this is a common question around here.
Purely theoretical, I was wondering if anyone knew why it HAS to be a yeast species that ferment sugars into drinking alcohol. Ethanol for biofuels is already made from many microorganisms for use in biofuels, so why couldn't someone genetically modify a bacteria or single-celled algae species for optimum beer-making? So far it seems to me that yeast is used because that is the convention and the public wouldn't want E. coli beer. Any thoughts?
