Comments "A common feature of the torque–speed relationships of E. coli and V. alginolyticus is a sharp knee between a “plateau” of nearly constant torque at low speeds and a much steeper linear decrease of torque with speed at higher speeds...In C. crescentus, motors operated in the plateau regime up to the highest speeds measured, ~320 Hz.(primary source)"
