Evolution and detection of cyanobacterial hepatotoxin synthetase genes [PDF]

open access: yes, 2007
Mass occurrences (blooms) of cyanobacteria are common in aquatic environments worldwide. These blooms are often toxic, due to the presence of hepatotoxins or neurotoxins. The most common cyanobacterial toxins are hepatotoxins: microcystins and nodularins.

Toxigenic Cyanobacteria and Microcystins in a Large Northern Oligotrophic Lake Onego, Russia

open access: yesToxins
Toxigenic cyanobacteria and microcystins in the oligotrophic pelagic zone and mesotrophic bay of Lake Onego—the second largest lake in Europe—were found for the first time. Microscopic analysis revealed that Dolichospermum lemmermannii, D.

Metabolomic Analysis of Both Microcystin-Producing and Microcystin-Free Microcystis aeruginosa Strains in Response to Exogenous Microcystin Exposure

open access: yesWater
Microcystis aeruginosa (M. aeruginosa), a key species in cyanobacterial blooms, is notably concerning due to its production of harmful microcystins (MCs). In this study, the differences in the ability of MC-producing and MC-free strains of M. aeruginosa to respond to the exogenous MCs (MC-LR) were compared.
