Epiphytic Algae

The photos below are taken through a microscope at 1000x and illuminated with ultraviolet light. They show bacteria stained with acridine orange to make them more visible. The bacteria were shaken off of Cladophora, a freshwater macro-algae, from the Eel River in Northern California. This summer I will conduct experiments to investigate the relationship between epiphytic bacteria and diatoms and their algal host Cladophora.


The photo below shows bacteria upon a diatom. I imagine the diatom is dead or dying and the bacteria are consuming the organic molecules from the decaying cell.
