Green Layer
Green layer
Filamentous cyanobacteria from the top (green) layer of a microbial mat in the Great Sippewisset Saltmarsh. Left: phase contrast, right: The same view after illumination with green light. The red autoflourescence demonstrates the presence of phycobiliproteins
Green layer
Some more filamentous cyanobacteria from the green layer of a microbial mat from the Great Sippewissett Saltmarsh. Left: phase contrast micrograph, right: autofluorescence of the same view after illumination with green light. Length of the borderline: approx. 0.4 mm
Green layer
A short fragment of the cyanobacterium Spirulina spec. (center) and a diatom. Left: phase contrast. Right: Autofluorescence of the same view after illumination with green light. The weak fluorescence of the diatom due to its chlorophyll a cannot be seen. Diameter of the microbes: approx: 3 µm
