You Need Yeast to Make Vegemite beer

Vegemite beer could be good for society.
There is a myth about Vegemite. It is assumed by many Australians to be unique. This isn't the case. Marmite and Bovril are the same product. It is yeast residue, the stuff at the bottom of the container when you brew your own beer with a lot of salt added.

Of course, the yeast is dormant and can still be activated. This is the case despite Vegemite spread being sterilized. The tasty "treat" is banned in Victorian prisons because it can be used to make an alcoholic concoction loosely called beer. Scientists actually made beer with Vegemite to prove that this is possible. Vegemite acted as a booster in the fermentation process. This made it possible for basic raw materials to be used to make beer.

There is one proviso: some natural yeast has To be obtained from somewhere else. Yeast naturally occurs on the skin of fruit and berries, so it is easy to get.  Just get some flour and add water.  It will start fermenting in a few days, so the prison ban is meaningless.

Ironically, a liter of Vegemite beer costs $0.24 to make. This compares to $1.28 for commercial beer. There could be a whole new market out there for an entrepreneur to begin manufacturing Vegemite beer for the ordinary consumer.

No More Poppies Needed to Produce Narcotics

Scientists have found a way of transforming ordinary sugar into hydrocodone. This will lead to a cheaper way of manufacturing opiates. Unfortunately, it will also make things easier for drug traffickers selling a cheaper product,
Hydrocodone made with yeast as catalyst
Yeast changes sugar into pain killer. This takes out the entire one year growing season for poppies and the factory process itself. At present, 4,400 gallons of yeast is needed to produce a small amount of hydrocodone. Work will proceed to improve this.

With yeast as the catalyst, it looks like plant-based medication manufacturing is under threat. Yeast has snippets of DNA added to reprogram cells into target compounds. Notably, a third of the world's supply of the medication artemisinin is already produced from modified yeast. Artemisinin needs six genes while hydrocodone requires 23. Some genes from rats arehydrocodone.

A "halfway-house" way of manufacturing pain killers is possible. A strain of yeast to make thebaine is available. It has to be processed in a factory to create the thebaine opiate, but it is cheaper than using poppies and is quicker.
