Figure 3

Fluorescence images of bitumen surfaces after 945 days of incubation in the microcosms. Images A and B show bitumen controls stained with the Syto9-lectin mix that were stored at 4 °C without incubation. Images C (microcosm 3) and D (microcosm 4) depict unstained controls of the bitumen surface in our microcosms after 945 days incubation. Images E–H show the bitumen surface of microcosms 1 (E and F), 3 (G), and 4 (H) after 945 days of incubation stained with the Syto9-lectin mix. All scale bars indicate 50 μm.
