Sadly, however, not all bacteria species are able to request help via tube. In the German team's experiments, E. coli were able to ask for nutrients from bacteria of an unrelated species, Acinetobacter baylyi. The requester E. coli also provided A. baylyi with nutrients as needed, presumably through the same nanotube. A. baylyi alone, however, didn't seem to exchange nutrients with each other, even when they were suffering from a lack of certain nutrients that other A. baylyi had access to. A. baylyi also never made nanotubes.
