WebCyanobacteria, also referred to as blue-green algae, are microscopic organisms that live primarily in fresh water but can also be found in brackish or salt water. An overgrowth of cyanobacteria is referred to as a “cyanobacterial bloom.” Cyanobacterial blooms are usually blue-green in color, but can be other colors, including red or brown. Weba. Non-Filamentous Type: The cells of this type divide either alternately or in three planes, thereby they form spherical (Gomphosphaera, Coelosphaerum), cubical (Eucapsis alpine, Fig. 3.23C), squarish (Merismopedia) or irregular (Microcystis, Fig. 3.23B) colony.
