, Dennis Smith’s superb book of San Francisco’s reaction to the 1906 earthquake, I got to thinking.What if I could precisely line up photos taken in 1906 with my own and combine the two together? Everything needs to be precise when layering two photos on top of each other.Synthetic THC is already available in pill form and it is used to ease nausea in cancer patients undergoing chemotherapy, or stimulate the appetites of people with H. Producing marijuana’s constituent compounds in vast quantities would give researchers a supply of marijuana’s myriad chemicals to better understand how, or if, they work as advertised.Still, at the moment, the plant is far more efficient than the yeast — modern marijuana strains can contain more than 30 percent THC by dry weight.
In August, scientists announced they had genetically engineered yeast to produce the painkiller hydrocodone, and even before that breakthrough, modified yeast churned out the anti-malarial drug artemisinin.
Unlike normal yeast, however, these custom yeast have to be fed cannabigerolic acid, which is a precursor molecule to THC and cannabidiol.
Using a molecular precursor as a starting point is a bit like reading a book from the middle chapters to its conclusion.
Now, scientists have customized yeast to create THC (the marijuana chemical that produces a “high”) and cannabidiol.
Biochemists from the Technical University in Dortmund, Germany, created a genetically-engineered yeast strain to produce very small amounts of THC or cannabidiol.
