If you are a vegan, then your choice of cheeses is very limited. On the today, manufacturers produce some high-quality cheeses, but most of them are soft – create Hard vegan cheese like Gouda or Cheddar is very difficult. But now it can change – a group of biohackers from San Francisco is developing a way to produce real vegan cheese. is he made from baker’s yeast that have been modified to produce true milk proteins. The result is product identical to cow cheese – but in the process of creating it the cow itself is absolutely not involved.

To get new yeast, the team isolated from animals genomes genetic sequences to create dairy proteins. Then these sequences were introduced into bakery yeast. After purification, the protein they produce must be mixed with vegan milk fat substitute, sugar (but not lactose), and water to get vegan milk. Then the turn begins The usual process for the production of milk cheese.
At the same time, the team emphasizes that their product is not genetically modified. Although the yeast itself undergoes a gene procedure modifications that they produce purified proteins do not modified. Abomasum used in production traditional cheese, get in a similar way, using genetically modified E. coli.

Team research is still in its early stages. By october they hope to receive and verify four dairy caseins, and also an enzyme that allows you to attach phosphate groups to these to proteins. Ideally, the team also hopes to demonstrate that can coagulate these ingredients in cheese.
In theory, this method allows you to create vegan cheese from DNA any mammal – including humans and other living things. If the team manages to achieve its crowdfunding campaign for collecting 20 thousand dollars for further research – they plan create cheese from narwhal DNA.
