- Description:
- Bacteria represent the most abundant form of life on Earth and have evolved to successfully colonize nearly every environmental niche. In doing so, bacteria predominately form multicellular communities known as biofilms, resulting in increased resilience, persistence, and emergent behaviors. Consequently, biofilms present an attractive target for engineering and synthetic biology,...
