Bacterial Biofilms are everywhere
Bacterial biofilms are found everywhere at the interface between solids and liquid or gas. They can be both destructive, e.g. biofilms in the lungs of people with cystic fibrosis can cause life-threatening infections, and constructive, e.g. biofilms are used to extract nitrites and nitrates from waste water in some water treatment facilities. Understanding biofilms is critical to their control in order to prevent their harmful effects and better utilize their assets.
The Chopp group has studied such issues as cell-cell communication, growth under various flow conditions, biofilms in activated sludge reactors, and even explored the capability of biofilms to generate electricity while they remove nitrates from waste water.
A list of the papers related to biofilms are shown below.
