Cyanobacteria: good-bad, blue-green, algae-not algae

Cyanobacteria: good-bad, blue-green, algae-not algae

Cyanobacteria, also known as blue-green algae because of their color, have endured for more than 2.5 billion years, providing ample time to adapt to changes in the Earth’s biosphere. They live in water where a diet heavy in nitrogen and phosphorus, combined with global warming, can prompt them to produce…
