Cyanobacteria is a large and diverse phylum in the kingdom Bacteria. Unlike eukaryotic plants and algae, cyanobacteria are prokaryotic organisms. They can be dangerous, such as when they cause infection, or beneficial, as in the process of fermentation (such as in wine) and that of decomposition. These organisms are oxygenic phototrophs , meaning they make energy from light and generate oxygen as a waste product. Monera Definition.
