I've known about biosynthetic cannabinoids for a while, but I never really dove into the research. Thankfully, Matt over at www.cannainsider.com recently had a podcast that explained it all. Kevin Chen, CEO of Hyasynth Bio, makes cannabinoids out of yeast. Instead of having a garden with soil, plants, sunshine, water, and months of time, Kevin grows cannabis with a big steel tank, water, yeast, air, and sugar, all in about a week. The genes of the yeast are modified to produce cannabinoids, which are extracted from the yeast culture once it's done fermenting. Common names for this process include genetic modification, synthetic biology, biosynthesized, cellular agriculture, and others. Check out the Hyasynth Bio website for a simple explanation on how their entire process works.
