Cyanobacteria are found almost everywhere, but particularly in lakes and in the ocean where, under high concentration of phosphorus conditions, they reproduce exponentially to form blooms. Blooming cyanobacteria can produce cyanotoxins in such concentrations that they can poison and even kill animals and humans.
Cyanobacteria may possess the ability to produce substances that could one day serve as anti-inflammatory agents and combat bacterial infections in humans. [259] Cyanobacteria's photosynthetic output of sugar and oxygen has been demonstrated to have therapeutic value in rats with heart attacks. [260]
The biosynthesis of saxitoxin is well-defined in cyanobacteria, while within dinoflagellates it remains mostly unknown. Cyanobacterial saxitoxin biosynthesis has been studied in radioisotope tracing experiments, and turns out to be highly complex, involving many steps, enzymes and chemical reactions.
Thanks to dozens of food recalls and a 10-year record for food borne illnesses, there were lots of dangerous foods this year. From romaine to raw meat, we have a few usual contenders as well as a ...
Exposure to lower levels of cyanide over a long period (e.g., after use of improperly processed cassava roots; cassava is a staple food in various parts of West Africa) results in increased blood cyanide levels, which can result in weakness and a variety of symptoms, including permanent paralysis, nervous lesions, [14] [15] [16] hypothyroidism ...

Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
Generally, however, these guidelines agree that highly processed foods contain high amounts of total and added sugars, fats, and/or salt, low amounts of dietary fiber, use industrial ingredients ...
