Aphanizomenon ovalisporum
caption
A filament of A. ovalisporum with 3 distinct heterocytes, cells in which N2 fixation takes place. This species was the first N2-fixing filamentous cyanobacterium that ever bloomed in Lake Kinneret. It happened in 1994 when this species formed an unprecedented autumn bloom. A. ovalisporum produces the toxin cylindrospermopsin, which makes it an undesirable species in this important source of drinking water. Aphanizomenon ovalisporum is abundant during summer and fall, being evenly distributed with depth throughout the epilimnion.
