We know yeast can make bread, beer and wine, but a new report from Chemistry World indicates that it can also be used for the real hard stuff: heroin.
I admit that I absolutely loved Breaking Bad, the TV series about mild-mannered chemistry teacher Walter White turned ruthless methamphetamine cook and drug lord. Bryan Cranston is an amazing actor, the writing was clever, the cast was a good ensemble, and it wasnt all goody-two-shoes morality play like most TV.
At the heart of the show was White aka Heisenburgs knowledge of chemistry and what it took to turn the various ingredients into that nifty blue meth all the tweakers feened for. It was complicated, cooking meth. It required exotic equipment, a knowledge of chemistry at the grad-school level and privacy.
But what if all of that could be cut out of the picture? What if all you had to do was mix some sugary substance up with some yeast, and wait? Well, youd get beer or wine, right? The yeast eats the sugar, and it craps out alcohol and carbon dioxide (remember that the next time you order a $500 bottle of wine youre paying for grape juice and yeast shit).
Lets suppose we can alter the yeasts genetic composition so that it excretes something more exotic, like opiates. I know, you wonder how much yeast shit Ive been ingesting while writing this. Sadly, not a bit, but let me share this with you from Chemistry World:
Genetically modified yeast can synthesise morphine and semisynthetic opioid pharmaceuticals, researchers in the U.S. have shown. This could obviate the need to grow opium poppies, reducing security concerns and the resulting regulatory hurdles, as well as the costs of chemically synthesising some of the synthetic opioids.
The researchers are now working to design a single integrated strain of yeast that can express all the enzymes necessary to convert simple sugars all the way to morphine or other target molecules, as well as further optimising the strains to increase the overall yields of the target molecules. Bioengineer Christina Smolke at Stanford said, From that point, you’re talking about basically scale-up and fermentation optimisation.
I dont know what the yields would be, but beer-drinkers neck billions of bottles a year. Thats what Smolke means by scale-up making a lot using the same process that you used to produce just a little. Organized crime could double or triple (or worse) its production.
John Collins, coordinator of an international drug policy project at the London School of Economics said, If these yeasts allow illicit drugs to be produced in meaningful quantities in the countries where they are consumed, then it could become a game-changer in terms of control. If it proliferates, I dont think there would be an easy answer there is not an answer to the current supply chain.
There are some things that biology can do to prevent the mob from profiting from this technology. Engineering the yeast to require particular nutrient supplements that are difficult to identify is one option. Greater security at labs goes without saying.
But in truth, if a technology exists, humans are likely to use it. Thats what we do. We can set up impediments to brewing smack, but if the money is right, someone somewhere will overcome them.
The problem, of course, isnt that we are making yeast that can crap heroin. The problem is that people want to take drugs for amusement, and heroin from yeast just makes it easier to get them. Stopping the production is impossible, and criminalization has failed. This biotechnology doesnt change the problem of addiction; the possibility of fermenting opiates has simply made it more important that we find an approach to addiction that works.
