A technique for producing THC and CBD with yeast has been discovered
With the fungus Saccharomyces cerevisiae Humanity has been creating staple products like bread, beer, and wine for millennia. This fungus is known as yeast.
This week the prestigious scientific journal Nature A technique for obtaining THC and CBD using yeast has been published. This technique was developed by scientists at the University of California, Berkeley.
The fungus's metabolism converts the sugars it is given into alcohol. But this new technique has managed, through several modifications to its metabolism, to generate cannabinoids.
Roberto Pérez, a researcher at IATA-CSIC in Valencia, explains that "the modifications to metabolism are carried out through genetic engineering, so that it produces compounds with a complex molecular structure and far removed from the compounds it usually produces.".
The resulting product (cannabinoids) would likely not be smoked. It could also be administered more precisely, producing only the desired effects and avoiding, for example, the typical high produced by THC or CBD. Furthermore, marijuana produces over 100 compounds that may have medical applications, but almost all of them are present in such small quantities that extracting them from the plant would be prohibitively expensive.
According to Evan Mills, a scientist at Lawrence Berkeley National Laboratory, the electricity consumed in the US by the legal greenhouse cannabis industry would be reduced by 1% (about $6 billion).
It is worth remembering that the authors of the technique, led by Jay Keasling, have already used yeasts to produce artemisinin (a drug used against malaria) or to convert plant waste into biofuel.
