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...Plateau torques appear to vary widely between
species, from ~3800 pN nm in V. alginolyticus,
through ~1300 pN nm in E. coli (in the most recent
estimate(primary source 3)), down to ~350 pN nm in Caulobacter
crescentus.(primary source 7)" |
