Microbes have evolved over millennia to become adapted and specialized to the environments that they occupy. These environments may include water or soil, extreme environments such as hydrothermal vents, and can even include a host organism...

Myxobacteria exhibit complex social traits during which large populations of cells coordinate their behaviors. An iconic example is their response to starvation: thousands of cells move by gliding motility to build a fruiting body in which ...

Microbial biofilms are encased in a protein, DNA, and polysaccharide matrix that protects the community, promotes interactions with the environment, and helps cells adhere together. The protein component of these matrices is often a remarka...
