Microcystis aeruginosa

Species: Microcystis aeruginosa

English Name: Microcystis aeruginosa

Chinese Name: 銅綠微囊藻

Family: Microcystaceae


A species of freshwater cyanobacteria which can form harmful algal blooms (HABs) that are of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic freshwater. Characterized by small cells (of only a few micrometers diameter), which lack individual sheaths. Cells usually are organized into colonies (large colonies of which may be viewed with the naked eye) that begin in a spherical shape, but losing their coherence to become perforated or irregularly shaped over time. The coloration of the protoplast is a light blue-green, appearing dark or brown due to optical effects of gas-filled vesicles.
