Cyanobacteria – Importance and Applications
Cyanobacteria, formerly termed blue-green algae, are ancient organisms with a profound impact on Earth's history. The ancestors of chloroplasts found in algae and plants, cyanobacteria were the first living cells to produce oxygen through photosynthesis, fundamentally altering our planet's atmosphere and enabling the evolution of all aerobic life forms. Today, cyanobacteria continue to shape our world. They play a crucial role in global carbon fixation, absorbing a substantial amount of carbon dioxide from the atmosphere. Additionally, cyanobacteria are being explored as a sustainable source for biofuels, offering a potential alternative to fossil fuels due to their ability to produce high-energy compounds. However, their blooms, particularly the toxic varieties, pose significant threats to aquatic ecosystems and water quality.
