<i>Caulobacter crescentus</i> eDNA (IMAGE) Indiana University Caption This is a fluorescence image of a Caulobacter crescentus biofilm. Cells are labeled in red, holdfasts are labeled in blue, and eDNA is labeled in green (appears yellow when superimposed within the red band of cells). Around the biofilm, individual cells can be seen, in some cases attached to each other by holdfasts coated by eDNA (green).
