Cyanobacteria are photosynthetic bacteria that can use water as an electron donor to produce oxygen during photosynthesis. They are often the first organisms to colonize a nutrient-poor aquatic environment and can form massive blooms if conditions are favorable, such as high levels of phosphorus and exposure to light. Green sulfur bacteria, green nonsulfur bacteria, and green algae are also photosynthetic, but they are less likely to flourish in water with limited nutrients like phosphorus.
