One cell about 2 µm long; fifty of them would span the width of a human hair. It swims by spinning a bundle of helical flagella, each turned by a rotary motor at around 100 revolutions per second. Inside: a tangle of DNA called the nucleoid.
From Living Bacilli to the Fabric of Spacetime Foam
A self-contained biological engine enclosed by a peptidoglycan cell wall and outer lipopolysaccharide membrane. Helical flagella rotate at 20,000 RPM driven by transmembrane proton-motive force.
