We enjoyed a great day at the 2019 Royal Norfolk Show. The group were busy introducing guests to the proteins that conduct electricity across bacterial cell walls and explaining how this behaviour inspires the development of sustainable biotechnology.  

Hello Habitat Hunters of the Norwich Science Festival 2018 

We asked you two questions. 

Q: How many bacteria are there in a teaspoon of soil?

A: Soil can contain as many as a billion (1,000,000,000) bacteria!! That's as many as all the people who live in Europe and the USA.

Q: How many different kinds of bacteria are there on Earth?

A: Short answer, no-one knows but we can try to make a good guess. Estimates of the number of species of microbes (bacteria, fungi and more) vary from around a million (1,000,000) up to a trillion (1,000,000,000,000)! We only know about 100,000 of them so far... ...  You can read more here.

Other facts:

  • there could be about 100,000,000,000,000 microbes living inside you right now, most of them are friendly and help you in lots of ways.

  • if all the viruses in the world were strung together they would reach over 100,000,000 light years, far enough to reach to other galaxies.

We're looking forward to the Norwich Science Festival 2018 and during Technology Day (Wednesday 24th October 2018) we'll be leading an interactive display demonstrating microbial fuel cells and using Virtual Reality to explore the structures of electrically conductive proteins. Experiments will show how different forms of energy are interconverted and allow you to identify electrically conductive materials with properties that explain how microbial fuel cells work.

In collaboration with the SAW Trust we participated in Latitude Festival 2018 with an interactive display ‘Life without oxygen?’
