Cyanobacteria are an immense source of several secondary natural products with applications in the food, pharmaceuticals, cosmetics, agriculture, and energy sectors. [11] Moreover, some species of cyanobacteria grow vigorously and form a dominant microflora in terms of their biomass and productivity in specific ecosystems.
The cyanobacteria Synechocystis and Cyanothece are important model organisms with potential applications in biotechnology for bioethanol production, food colorings, as a source of human and animal food, dietary supplements and raw materials. [21]
Cycads harbor symbiotic cyanobacteria of the genus Nostoc in specialized roots which push up through the leaf litter into the light; these cyanobacteria produce BMAA. [32] In addition to eating traditional food items from cycad flour directly, BMAA may be ingested by humans through biomagnification.
According to the Walworth County DHHS, "Blue-green algae are photosynthetic bacteria known as 'cyanobacteria,' which can cause illness and death in humans and animals. Blue-green algae are a ...
Microcystis aeruginosa is a species of freshwater cyanobacteria that can form harmful algal blooms of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic fresh water. Cyanobacteria produce neurotoxins and peptide hepatotoxins, such as microcystin and cyanopeptolin. [1]
The oral LD50 for humans is 5.7 μg/kg, therefore approximately 0.57 mg of saxitoxin is lethal if ingested and the lethal dose by injection is about one-tenth of that (approximately 0.6 μg/kg). The human inhalation toxicity of aerosolized saxitoxin is estimated to be 5 mg·min/m 3. Saxitoxin can enter the body via open wounds and a lethal dose ...
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 ...
