The effect of cyanobacterial biomass enrichment by centrifugation and GF/C filtration on subsequent microcystin measurement
(http://www.mdpi.com/2072-6651/7/3/821/htm, 2015-03)Microcystins are cyclic peptides produced by multiple cyanobacterial genera. After accumulation in the liver of animals they inhibit eukaryotic serine/threonine protein phosphatases, causing liver disease or death. Accurate ... -
Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study
(International Society of Limnology, 2012)An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no ... -
Potent toxins in Arctic environments – Presence of saxitoxins and an unusual microcystin variant in Arctic freshwater ecosystems
(2013)Cyanobacteria are the predominant phototrophs in freshwater ecosystems of the polar regions where they commonly form extensive benthic mats. Despite their major biological role in these ecosystems, little attention has ... -
Switching toxin production on and off: intermittent microcystin synthesis in a Microcystis bloom
(Wiley InterScience, 2010)Toxic cyanobacterial blooms are increasing in prevalence. Microcystins are the most commonly produced cyanotoxin. Despite extensive research the variables regulating microcystin production remain unclear. Using a RT-QPCR ... -
Temperature-related changes in polar cyanobacterial mat diversity and toxin production
(Nature Publishing Group, 2012)One of the fastest rates of recent climate warming has been reported for the Arctic and the maritime Antarctic; for example, mean annual temperatures increased by 0.5 °C per decade over the Antarctic Peninsula during the ...
