Care for a glass of fresh-brewed mammoth milk?
Two start-ups developing processes to produce milk and leather using yeast instead of animals have received backing to help move their work out of the lab and closer to consumers.
Berkeley, Calif.-based Perfect Day, which aims to produce milk proteins via fermentation, raised $24.7 million in its first round of venture funding from Temasek, a Singaporean state-owned investment company; Hong Kong-based Horizons Ventures; and Inconiq Capital, a group of Silicon Valley investors.
Across the country in Nutley, N.J., Modern Meadow has struck a deal with German specialty chemical firm Evonik Industries. The companies will work together to scale up fermentation yield and output of collagen, which Modern Meadow uses to produce a material it calls bioleather. The investment firms that are behind Perfect Day are also investors in Modern Meadow.
Chief Technology Officer Dave Williamson says Modern Meadow wants to increase its scale by an order of magnitude and move into commercial production.
“Evonik is a clear leader in microbial fermentation, and their innovation and production capacity convinced us that they are the right partner for this critical program,” Williamson says. Evonik uses large-scale fermentation to make amino acids for its animal nutrition business.
While producing amino acids via fermentation is common industrial practice, making milk and leather proteins without the moo is a specialty process more akin to craft brewing. Both start-ups rely on yeast genetically altered to contain mammalian DNA.
According to a 2014 patent, Perfect Day’s modified yeast process can make the specific milk proteins of just about any animal, including humans, pandas, lemurs, whales, spiny anteaters, and even woolly mammoths.
