Denmark based biology company Octarine started to produce psilocybin via a brewers yeast called Saccharomyces cerevisiae. While producing less than previous strains of bacteria and yeast this has proven to be the cheapest method. While losing about half of the production to psilocin conversion they are trying to work through those issues. They believe that the yeast processes are too similar to our stomach digestion and converting the psilocybin to psilocin. While still useful and may have a higher binding rate to Serotonin receptors, they are trying to make more psilocybin as that’s what they are testing. The reason for all of this is to make psilocybin more available to scientists and healthcare researchers. The current models are very expensive to get traditionally extracted psilocybin via good practice methods. This a step for companies be able to collect more data and run more tests at a cheaper rate.
