Scientists have introduced it cannabis plant genes in yeast, where microorganisms produce THC and other cannabinoids.
researchers have modified the yeast so that these yeasts produce cannabis plants. Some of these cannabinoids are used as pharmaceuticals. Scientists hope their biotechnology process will help in the production of new cheaper drugs.
THC and cannabinoids have wide use in medicine
Cannabinoids are nowadays used for different purposes – against nausea after chemotherapy, to stimulate appetite in patients with AIDS or against certain forms of epilepsy. Other potential uses are currently under study.
Medical use, however complicate the strict laws and changing content of most cannabinoids in plants, The problem was described by Jay Keasling of the University of California at Berkeley in the journal Nature. Since there are drugs such as hashish and marijuana obtained from hemp, it is its cultivation almost everywhere strictly regulated.
Keasling and his colleagues applied the genes of the hemp plant to brewer's yeast cells. The yeast was able to produce cannabinoid acid cannabis and also produce a psychoactive substance (THC) or cannabidiol (CBD) and many other substances.
Total researchers created more than 50 artificial yeast strains, than product different amounts of different cannabinoids.
"The benefits to consumers are high quality and low costs, yeast produces exactly what you want," says Keasling.
Among the benefits, according to scientists, is the fact that biotech production is compared to conventional hemp more respectful of the environment.
than
also considered the possibility of modifying natural cannabinoids for artificial production
cannabinoids that are not found in cannabis plants. It worked
using fatty acids instead of galactose, that is, a food base
for modified yeast strains.
Scientists in California have already started trading with their technology. This approach is not entirely new when using drugs containing microorganisms. Yeasts can also produce different substances including insulin, growth hormones, blood clotting factors and opiates.
