Of the genus Microcystis (Cyanobacteria, chroococales), M. wesenbergii is the easiest species to identify: the spherical cells are relatively large (5-8 µm) and are embedded in thick colorless homogeneous mucilage with clearly defined contours. It is generally less abundant in Lake Kinneret than M. aeruginosa and M. flos aquae.

Thioploca is a genus of bacteria that are known for their unique lifestyle and morphology. They are notable for forming long, thread-like chains of cells that can reach several centimeters in length. These bacteria are found in marine environments, particularly in oxygen-deficient sediments rich in hydrogen sulfide.
This beautiful picture taken by Carola Espinoza shows a bundle of sheathed Thioploca chileae. The polysacharide sheath is seen as a transparent sleeve. This allows Thioploca trichomes to slide up and down within the sediment which allows the organism to obtain nitrate from the overlying water and hydrogen sulfide from the depths of the sediment layer. The bar depicts 10 micrometers.

Collected in the wetlands of national park Unteres Odertal (100 km north east of Berlin). The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.

Siderocapsa species. Siderocapsa belongs to iron bacteria. Every colony of Siderocapsa cells build a brown gelatinous annulus which give shelter. They gain energy by oxidizing dissolved ferrous iron or/and manganese. The metabolite ferric oxide is insoluble, and appears as brown deposit in the gelatinous slime. Sample from a little creek near Kiel. This image was taken using Zeiss Universal with Olympus C7070 CCD camera.
