Light micrograph of purple bacteria from a sulphuretum. The bottom of this small water body is permanently anaerobic due to the decaying plant inputs, and in this milieu there is a society of predominantly anaerobic microorganisms that reduce or oxidise sulphur. Such an ecosystem is called a sulphuretum. The picture shows a colony of purple bacteria, probably belonging to the genus Thiocapsa, recognisable by its purple colour. Furthermore, a colony of green algae of the genus Coelastrum and a filamentous green alga of the genus Spirogyra can be seen. Microscopic contrast method : dark field.
