Cyanobacterial toxins in Italian freshwaters

Abstract: This study focuses on the occurrence and distribution of cyanobacterial toxins from 1989 to 2006 in several Italian lakes of different characteristics and human uses, the latter including drinking water abstraction and recreation. Phytoplankton and LC/MS/MS toxin analyses were performed on surface water samples collected from 28 lakes. The most widespread species associated with toxin production belonged to the genera Microcystis, Planktothrix and Anabaena. Extracellular concentrations varied from non-detectab… Show more

“…of the blooms, while Dolichospermum bloomed in 2003, but after that low densities were reported sporadically over the years (Sulis et al, 2014). The overall density of CB community during our study was about 10 times lower than what was observed before (Messineo et al, 2009;Sulis et al, 2014), but an even more complex alternation of species was observed. P. rubescens was always present and generally dominant until summer 2012, with the typical trend of depth blooms in summer and more homogeneous distribution along the water column during the other seasons (Kurmayer et al, 2016).…”

“…The CB with the highest density described so far are the Planktothrix and Microcystis genera, which have been responsible for the most frequent onset of blooms, while the Dolichospermum genus, except for a bloom in 2003, appeared sporadically (Sulis et al, 2014). To our knowledge, data on MCs in this lake have been assessed only in two occasions and were associated with the presence of P. rubescens (Messineo et al, 2009;Sulis et al, 2014). A recent 18-month study on four reservoirs in Northern Sardinia showed significantly different seasonal variations in CB community composition, with several toxigenic species, and large variability in MCs concentrations (Mariani et al, 2015).…”

“…Evidence is accumulating, however, to show that strains belonging to this species also synthesize CYN elsewhere. The toxin has been reported in freshwater bodies in Italy (Messineo et al, 2009), the Czech Republic (Bláhová et al, 2009), Poland (Kokocinski et al, 2009) and France (Brient et al, 2009), which contained Aph. flos-aquae, Aph.…”
