The bacteria preferentially swim to one side of the system under the influence of the ratchet. We tested the effects of different bacteria-wall interactions on the ratcheting efficiency. We also implemented interactions among the bacteria, including steric and flocking interactions. In some cases, the interactions increase the rectification effect, while in others, the rectification is destroyed.
