Cyanobacteria—Blue-Green Algae
Cyanobacteria, also known as the blue-green algae, are photosynthetic prokaryotic organisms utilizing chlorophyll a. Unlike other photosyn- thetic bacteria, the cyanobacteria evolve oxygen and may have been responsible for the early accumulation of oxygen in Earth’s atmosphere. Species may be characterized by the formation of akinetes—thick- walled non-motile spores, and heterocysts—thick-walled translucent cells capable of fixing nitrogen.
★MAINTENANCE: Culture blue-greens under moderate to low light in Bristol’s Modified Medium or Pringsheim’s Soil Water.
