Microcystis flos-aquae

Species: Microcystis flos-aquae

English Name: Microcystis flos-aquae

Chinese Name: 水華微囊藻

Family: Microcystaceae


A gas-vacuolate cyanobacterium species that forms colonies of cells in freshwater. The dominance of these species is attributed to their ability to float in water and their ability to regulate their buoyancy as a response to environmental changes. The cell diameters of these species are of 2.5-5.5 micrometers.
