Cyanobacteria Collection (#3)

Blue-green algae
Stigonema algae. Light micrograph of filaments of the blue-green algae Stigonema ocellatum. The name " Stigonema" translates from latin

Blue-green alga, Spirulina platensis
False colour transmission electron micrograph of the blue-green algae, Spirulina platensis. Here, a single cell of this species is seen. Blue-green algae (cyanobacteria) are primitive algae

Stromatolites. These are mineralised microbial communities, formed from blue-green algae (also called cyanobacteria). Over the last 4000 years

Lichen, light micrograph
Lichen. Light micrograph of a section through tissue of a lichen. Lichens are symbiotic associations of a fungus (the mycobiont) with a photosynthetic partner (the photobiont)

Stromatolites at Hamelin Pool, Shark Bay, western Australia. These are living representatives of the oldest living
ROG-13733 Stromatolites at Hamelin Pool, Shark Bay, western Australia These are living representatives of the oldest living organisms, over 3.5 billion years old as fossils

Cyanobacteria, also known as Microcystis blue-green alga, are fascinating organisms that thrive in various environments. From the elevated view of patterns in bacterial mats around Grand Prismatic Spring in Yellowstone National Park to the dead calcified trees adorned with vibrant yellow and brown cyanobacteria living in Canary Springs, their presence is both mesmerizing and vital. At Mammoth Hot Springs, the Canary Spring terraces greet the sunrise with a burst of colors, thanks to the cyanobacteria residing there. The travertine slope showcases a picturesque scene with its stunning yellow and brown hues created by these microorganisms. Steaming mist envelops Canary Spring at dawn, creating an ethereal atmosphere at Mammoth Hot Springs. Meanwhile, Grand Prismatic Spring offers another breathtaking sight from above as intricate patterns emerge within its bacterial mat. Beyond Yellowstone National Park lies the Sargasso Sea in Bermuda where Trichodesmium thiebautii thrives. These blue-green cyanobacteria add a touch of beauty to this marine ecosystem. However, not all encounters with they have positive outcomes. In Lake Baikal, Siberia's pristine waters suffer from sick sponges stricken by these microorganisms during December. It serves as a reminder of how delicate ecosystems can be affected by imbalances caused by certain species. In Lake Natron's Rift Valley salt pans, an aerial view reveals striking red hues due to an abundance of cyanobacteria. This phenomenon showcases nature's ability to transform landscapes into surreal works of art through microscopic life forms like these bacteria.
