IANAM (not a microbiologist): I believe that it is achieved through CRISPR edited yeast, or possibly another easily cultured bacterial species (E. Coli perhaps?). The cells replicate and are then portioned and lysed, the solution is spun down in a centrifuge, separated for waste and the yield extracted and purified.
