Caption

This image is a transmission electron micrograph (TEM) image of a single commensal bacterium, E. coli Nissle 1917, which has been genetically engineered to express gas-filled protein nanostructures known as gas vesicles. The cell is approximately 2 micrometers in length, and the lighter-colored structures contained inside of it are individual gas vesicles.
