Microbes – Friend or Foe?

Course Level 1: Introductory

Estimated Study Time: 10-12 hours

Microbes often get a bad name. Whilst some of them do cause disease, others play vital roles in recycling nutrients in the soil to enable plants to grow, and in breaking down human waste. Without microbes, we would have no beer, no yogurt, no coffee. That’s quite impressive for something too small to see. This course sheds some light on them.

This course looks at two aspects of microbes. The first section covers the way that bacteria cause disease and how they can become resistant to the antibiotics used to treat them. The second covers the important role that microbes play in treating sewage to purify the water so that it can be returned to rivers or to the sea.
