Microbes

Between thinking about the AI exam, shopping and java exercises, I've been watching the following video by the Open University about the wonders of the microbe world.

It briefly covers

• yeast in beer making in ancient Egypt
• the Black Death
• preserving food
• microbes fixing nitrogen in the soil by combining it with hydrogen or oxygen
• microbes helping digest food
• antibiotics produced by one microbe to kill other microbes
• using e. coli to produce, for example, insulin and treatments for AIDS
