Cyanobacteria

Cyanobacteria, also known as blue-green algae, are microscopic, photosynthetic bacteria found in water, soil, and aquatic environments. They play a vital role in producing oxygen through photosynthesis and can form colorful, algae-like blooms in water bodies. Some species can fix atmospheric nitrogen, enriching ecosystems. While they are important for the environment, certain cyanobacteria can produce toxins that pose risks to aquatic life, animals, and humans. They thrive in warm, nutrient-rich waters, and their presence often signals ecological changes, such as nutrient pollution. Cyanobacteria are essential components of many ecosystems but require careful management due to their potential health impacts.
