You would be surprised, yeast vats and breweries have a ton of overlap, IE pretty cheap tanks and reasonably standard infrastructure. Most universities with a biology research wing are going to have a few bio-reactors, and while they may not be able to produce the feed itself industrially, they can easily breed starters to sell to places like breweries and companies that already produce yeast at massive scale.
