Abstract:
Cyanobacteria are recognised globally as a human health threat due to their proliferation into toxic blooms. Of particular concern are strains that produce the hepatotoxins, microcystin and nodularin. Research over the past decade has revealed the biochemical and molecular mechanisms behind hepatotoxin production. However, there is still much to learn regarding the regulation of these biologically active metabolites. This review provides an overview of cyanobacterial hepatotoxin research to date and additionally, elaborates on the putative involvement of nitrogen and iron homeostatic mechanisms in cyanotoxin regulation.
