Bio-based production of psilocybin has garnered major interest and researchers have already proved small-scale production in E. coli. However, production in bacteria comes with a wide range of concerns which can be addressed by using yeast instead.

In yeast, the scientists prove that psilocybin can be produced de novo, which means that you can produce the molecule by simply growing the yeast with sugar and other nutrients, without the need to add any other starting substrates.
