Is there SPIRULINA (Cyanobacteria) in the food you feed your Fish?
Cyanobacteria what is it? Is it a micro or macro algae is it a bacteria?
Spirulina is an organism that grows in both fresh and salt water. It is a type of cyanobacteria, which is a family of single-celled microbes that are often referred to as blue-green algae. Just like plants, cyanobacteria can produce energy from sunlight via a process called photosynthesis.
But Spirulina may become contaminated with toxic metals, harmful bacteria and microcystins — toxins produced from some algae —if it is grown in unsafe conditions. Contaminated Spirulina can cause liver damage, nausea, vomiting, thirst, weakness, rapid heartbeat, shock and even death.
Microcystins are toxins produced by cyanobacteria. Cyanobacteria are also known as blue-green algae and are ubiquitous in surface water when conditions are favourable for growth and formation of algal blooms. Cyanobacteria release toxins upon cell death or lysis.
Microcystins — or cyanoginosins — are a class of toxins produced by certain freshwater blue-green algae. Over 50 different microcystins have been discovered so far, of which microcystin-LR is the most common. Chemically they are cyclic heptapeptides produced through nonribosomal peptide synthases.
