It is one of the dominating species during the extensive cyanobacterial blooms in the Baltic Sea, which are one of the largest in the world. N. spumigena, which on average, represented >90% of the total phytoplankton biovolume.

It is one of the dominating species during the extensive cyanobacterial blooms in the Baltic Sea, which are one of the largest in the world. N. spumigena, which on average, represented >90% of the total phytoplankton biovolume. Anabaenopsis arnoldii Aptekarj (Figure 1b) was subdominant throughout the bloom and co-occurred with a number of diatom species, notably Chaetoceras spp. Figure 2.

Det är främst dessa algblomningar som kan vara giftiga för djur och barn som råkar få i sig mycket av vattnet. Det finns fem arter av nodularia i Östersjön, men det är endast Nodularia spumigena, som finns i hela Östersjön. The bloom-forming cyanobacterium Nodularia spumigena CENA596 encodes the biosynthetic gene clusters (BGCs) of the known natural products nodularins, spumigins, anabaenopeptins/namalides, aeruginosins, mycosporin-like amino acids, and scytonemin, along with the terpenoid geosmin.

Nitrogen, iron, and silica are widely considered to be the most important nutrients that limit phytoplankton growth in the world's oceans. Though clearly important in lakes, the role of phosphorus has been largely ignored in the ocean. In part, this is because of early studies that suggested there was excess phosphate (P) relative to the needs of the phytoplankton in open ocean waters.
