WebThe growth of bacteria with varying oxygen requirements in thioglycolate tubes is illustrated in Figure 9.20. In tube A, all the growth is seen at the top of the tube. The bacteria are obligate (strict) aerobe s that cannot grow without an abundant supply of oxygen. Tube B looks like the opposite of tube A. Bacteria grow at the bottom of tube B.

We show that, in such environments, physical limits on the accuracy of temporal gradient sensing govern when and where bacteria can accurately measure the cues they use to navigate.
