Aphanizomenon flos-aquae Aphanizomenon flos-aquae Aphanizomenon flos-aquae is a brackish and freshwater species of cyanobacteria found around the world, including the Baltic Sea and the Great Lakes. "Aphanizomenon flos-aquae" can form dense surface aggregations in freshwater (known as "cyanobacterial blooms"). These blooms occur in areas of high nutrient loading, historical or current. "Aphanizomenon flos-aquae" has both toxic and nontoxic forms. Most sources worldwide are toxic, containing both hepatic and neuroendotoxins. Most cyanobacteria (including "Aphanizomenon") produce BMAA, a neurotoxin amino acid implicated in ALS/Parkinsonism. Toxicity of "A. flos-aquae" has been reported in Canada, Germany and China. "Aphanizomenon flos-aquae" is known to produce endotoxins, the
