AuX Labs Taps Microbrewery Equipment to Scale Animal-Free Casein

AuX Labs secured $4 million in funding to produce recombinant casein—a functional dairy protein—through precision fermentation in existing microbrewery bioreactors. Rather than building dedicated facilities, the startup leverages excess capacity at struggling craft breweries, addressing both their economic pressures and its own capital constraints. The B2B ingredient approach targets food formulators seeking vegan cheese with dairy-like melting and texture properties. Worth flagging: scaling precision fermentation introduces complexity across distributed facilities with varying equipment specifications, though the brewery model may optimize regional supply chains.
