Cyanobacteria or Blue-Green Algea?
Because they superficially resemble algae, are photosynthetic and live in water, cyanobacteria are called "blue-green algae." However cyanobacteria are relatives of the bacteria. They are not eukaryotes. It is only the chloroplast in eukaryotic algae to which cyanbacteria are related. In a similiar vein, some dinoflagellates contain a second nucleas that is beleived to be part of a membrane-bound endosymboint within the cytoplasm of the dinoflagellate. The presumed endosymboint's cytoplasm contains not just nucleus, but also chloroplasts, mitochondria and ribosomes. Thus some groups of algae may have obtained chloroplasts from other symbiotic eukaryotic algae instead from symbiotic prokaryotes.
Cyanobacteria cannot tolerate a large sudden change in salinity. High alkalinity will promote rapid growth of calcifying algea such as a dark red coraline or green halimeda, while stunting the growth of cyanobacteria. A low alkalinity will stunt the growth of calcifying algae which will allow cyanobacteria to thrive while growing on rocks, corals, and sand. Allthough a high alkalinity will resolve a cyanobacteria breakout it will also stunt the growth of many green algae.
Cyanobacteri is responsible for leaving the oldest known fossils more than 3.5 billion years ago. It is not Sexually reproductive and produ8ces specialized thickened cells called akinetes that are full of food reserves.
The cyanobacterium Spirulina, now a popular health food has long been valued for its high protein content, and ease of cultivating in ponds.
Strong water flow to prevent growth on sand, activated carbon use, protein skimmimg, ozone, strong water circulation or other means of increasing redox potential of the water and reducing the accumulation of dissolved organic compounds, elevate alkalinity.
Only known species to eat cyanobacteria, Clibanarius Tricolor, Apylsi, Bursatella, Strombus Alatus, Ctenochaetus. <---- dont ask me what they are.
