Autotrophic Microorganisms Research Centre,
photographed through a light microscope by
Dr. Claudio Sili.

This small photographic exhibition shows the suggestive images of some of the microalgae present in the river Arno during the summer season. Let's observe them for what they are in all their beauty as living organisms.   The danger they represent is due exclusively to the fact that human activities have created an imbalance thus rendering the river unhealthy.   What we can see in the images is the morphological aspect of some algae studied in the Florentine stretch of the river at Isolotto.
