The traditional genus Aphanizomenon comprises a group of filamentous nitrogen-fixing
cyanobacteria of which several memebers are able to develop blooms and to produce toxic …

Cyanobacteria (blue-green algae) are Gram-negative oxygenic photosynthetic prokaryotes
with a long evolutionary history. They have potential applications in diverse areas …

The new genus name Dolichospermum, for most of the planktonic former members of the
genus Anabaena, is one of the most ubiquitous bloom-forming cyanobacterial genera. Its …

Cylindrospermopsin is an important cyanobacterial toxin found in water bodies worldwide.
The ever-increasing and global occurrence of massive and prolonged blooms of …

The growth and intracellular microcystin concentration of two hepatotoxic and two nontoxic
axenic Microcystis strains were measured in batch cultures with variable nitrogen (0.84-84 …

Cyanobacterial mass occurrences in freshwater lakes are generally formed by Anabaena,
Microcystis, and Planktothrix, which may produce cyclic heptapeptide hepatotoxins …

The heterocytous cyanobacteria form a monophyletic group according to 16S rRNA gene
sequence data. Within this group, phylogenetic and morphological studies have shown that …

Microcystins are harmful hepatotoxins produced by many, but not all strains of the
cyanobacterial genera Anabaena, Microcystis, Anabaena, Planktothrix, and Nostoc …

The cluster of microcystin synthetase genes from Anabaena strain 90 was sequenced and
characterized. The total size of the region is 55.4 kb, and the genes are organized in three …

The cyanobacterial hepatotoxins, microcystin and nodularin, are produced by a wide range
of cyanobacteria. Microcystin production has been reported in the four cyanobacterial …
