Real Vegan Cheese

The goal of this project is to make real vegan cheese by engineering normal baker's yeast (S. cerevisiae) to express milk protein (casein), purifying the protein, creating a milk-substitute by blending in vegan replacements for lactose and milkfat, and finally turning the resulting milk-substitute into semi-hard cheese like gouda using the normal cheese-making process. Watch a brief video about the project.

The main challenges include:

• Biology
  • Getting the major casein proteins expressed, and ideally secreted.
  • Achieving a high level of expression.
  • Ensuring any necessary post-translational modifications take place.
  • Cost-efficient protein purification.
  • Stable micelle-formation.
  • Finding a suitable milk-fat replacement.
  • Finding a suitable lactose replacement

• Ethical, Legal, and Social Implications
  • A comparison between yeast bioreactors and dairy cows will be essential
  • Life Cycle Analyses

• Safety
  • Ensuring a safe and responsible research environment is already a key goal of CCL and BioC, but we will have to field potential safety concerns specifically related to the Real Vegan Cheese project.

• Funding and spreading the word
  • We have raised about $37,000 on indiegogo and the funding we raised is being used on developing the feasibility of producing Real Vegan Cheese from baker's yeast.

• Patents
  • We plan to patent and abandon to keep this technology free for everyone

• Education
  • Providing hands-on lab training.
