Indeed, cannabinoids made from yeast are the same cannabinoids the plant makes. “Ultimately, a molecule is a molecule,” says Raber. This is known as the entourage effect: CBD, for instance, seems to attenuate the psychoactive effects of THC.īy selectively churning out these cannabinoids in the lab, it’ll be easier for researchers to play with them in isolation and with each other, without having to wade through hundreds of other compounds you’d find in pure flower. Regardless of production hurdles, the beauty of this kind of bioengineering is that it gives researchers a powerful platform to dig into not just what each cannabinoid might be useful for-whether treating anxiety or inflammation or epilepsy-but how the many cannabinoids in the plant might interact with one another. “Can you keep making it highly concentrated, or does it become toxic to the organisms that you're actually using to produce it, and therefore you have a limit?” asks Jeff Raber, CEO of the Werc Shop, a lab that’s picking apart the components of cannabis. That is, you’d want optimize your yeast to churn out a whole lot of product. (Which is not to say some folks won't still appreciate their cannabis grown the old fashioned way.) But to make it as efficient as possible, you’d need to work with the highest possible concentrations of cannabinoids. The idea is that you could crank out vast amounts of CBD in vats far more easily than by planting greenhouse after greenhouse of cannabis plants. “CBGA is this kind of central cannabinoid that's the mother of all the other cannabinoids,” says UC Berkeley chemical engineer Jay Keasling, coauthor on a new paper in Nature detailing the technique.įor cannabinoids, the key benefit is scale. Importantly, both carry the cannabis genes that produce CBGA. Two different yeasts produce either THC or CBD, depending on what kind of enzyme they carry. It’s a clever scheme in a larger movement to methodically pick apart and recreate marijuana’s many compounds, to better understand the plant’s true potential. By loading brewer’s yeast with genes from the cannabis plant, they’ve turned the miracle microbes into cannabinoid factories. Now researchers have turned to yeast to do something more improbable: manufacturing the cannabis compounds CBD and THC. And I don’t even want to begin to imagine a world without beer and wine, which rely on yeast to convert sugar into alcohol. Baker's yeast has given us leavened bread for thousands of years. 268-286.We as a species would be miserable without yeast.

The results show that PGSA-GA is quite suitable for structural optimization. Through the examples of typical truss and single-layer lattice shell, it shows that the optimization efficiency and effect of PGSA-GA are better than those of other algorithms and methods, such as GA, secondary optimization method, etc.
