Cyanobacteria
Cyanobacteria are the largest phylum of Gram-positive prokaryotes on earth dating back to 3.5 billion years ago[1]. They evolved the ability to use photosynthesis to obtain their energy, making them different from other single celled organisms at the time [2]. By photosynthesizing, the Cyanobacteria produce oxygen as a byproduct. This is believed to have both helped the bacteria successfully prosper because the environment in which they were developing was otherwise occupied by anaerobic bacteria and caused the Great Oxidation Event [3]. The Great Oxidation Event is where the earth first experiences a rise in the amount of oxygen in the atmosphere and oceans[4].
Many species live in large colonies of cells ranging from hundreds to thousands of cells in a single colony [5]. These colonies are able to form filaments, sheets, or hollow spheres [6]. When too large, they can form harmful algal blooms that can cause great harm to the aquatic ecosystem and the surrounding area it is in [7].
Cyanobacteria are wide spread around the world, contributing to major global biogeochemical cycles like cellular death [8].
