Bacterial biofilms: Did you know they can help us?

Bacteria are tiny organisms that we cannot see with our naked eye. In nature they live in social groups called biofilms. To build biofilms bacteria produce a sticky material that works like a glue, called the biofilm matrix, that helps the bacteria stick to each other and to surfaces. Although some types of biofilms can be harmful, a lot of biofilms are very useful for humans. In this article we will give you examples of the amazing things biofilms can do for us, from helping remove oil spills in the oceans to helping our plants and crops stay healthy! There is an animation you can watch and an illustration you can explore. We hope you enjoy learning about beneficial biofilms.
