"vegan cheese" entries
Synthetic biology surely can get weirder — but this is a great start.
If you’ve ever tried any of the various vegan cheese substitutes, they are (to put it kindly) awful. The missing ingredient in these products is the milk proteins, or caseins. And of course you can’t use real milk proteins in a vegan product.
But proteins are just organic compounds that are produced, in abundance, by any living cell. And synthetic biology is about engineering cell DNA to produce whatever proteins we want. That’s the central idea behind the Real Vegan Cheese project: can we design yeast to produce the caseins we need for cheese, without involving any animals? There’s no reason we can’t. Once we have the milk proteins, we can use traditional processes to make the cheese. No cows (or sheep, or goats) involved, just genetically modified yeast. And you never eat the yeast; they stay behind at the brewery.
