“…Microcystin extraction from phytoplankton samples was performed as previously described (Karlsson et al, 2005b;Vareli et al, 2009a) with minor modifications as follows: 2-15 mg of lyophilized phytoplankton pellets were added to 2 ml of 75% methanol in water and 0.5 g zirconium beads (0.1 mm diameter). The samples were homogenized for 5 min by vigorous shaking (5000 rpm) on a Mini Bead-beater (Biospec products, Bartlesville, OK, USA) with intermittent cooling on ice.…”

“…Cyanobacterial blooms have also frequently occurred concerning the shallow, warm Lake Pamvotis (Greece) as reported by Vardaka et al (2005), Gkelis et al (2005), Kagalou et al (2008), Vareli et al (2009), Papadimitriou et al (2010. Since Lake Pamvotis has a long eutrophication history (Kagalou et al 2008), it would be advisable to verify and quantify any toxins that may be present, offering also evaluation of lake toxicity.…”

Lake Pamvotis is a shallow, eutrophic Mediterranean lake with ecological significance. This paper deals with the evaluation of cyanobacterial toxicity in Lake Pamvotis. ELISA and HPLC revealed the presence of significant amounts of MCYST-LR. Danio rerio bioassay confirmed the toxic nature of the bloom. Cyanobacterial extracts had adverse toxic effects on development of D. rerio. Also, it was shown that cyanobacterial extracts containing environmentally detected concentrations of MCYST can cause reduced survival rate of fish species. The results clearly indicate that cyanobacterial blooms in Lake Pamvotis may be regarded as human and fish health hazard. Continuous monitoring of the lake is suggested, in order to prevent future possible intoxications.

“…For this reason, traditionally this species has been considered a coldwater stenotherm cyanobacterium. Nevertheless, besides the more recent discovery of populations living in Eastern Europe (Vasas et al, 2013), records of this species were documented in many Mediterranean regions, including Central and Southern Italy ( Messineo et al, 2006;Assennato et al, 2010), Sicily (Naselli-Flores and Barone, 2000), Spain (Almodóvar et al, 2004), Greece (Vareli et al, 2009) and Turkey (Akçaalan et al, 2014;Köker et al, 2017). More recently, this species has also been identified in Northern Africa (Guellati et al, 2017).…”

Among cyanobacteria, Planktothrix rubescens (De Candolle ex Gomont) Anagnostidis & Komárek is a species that is well adapted to develop in moderately nutrient rich and deep lakes. In this typology of waterbodies, the competitive abilities of this species rely in its capacity to stand and growth in the dimly illuminated metalimnetic layer during the warmer months. In this work, we have studied the seasonal development and distribution of this species in Lake Ledro, a meso-oligotrophic reservoir located in the Eastern Alps. During the last decade, this species has given rise to numerous and extended surface bloom episodes, causing the reddening of vast areas of the lake. In summer, the light intensities in the zone of greater development of this cyanobacterium (the metalimnion, between the euphotic depth and the layer of maximum development of the species) were between 2 and 20 µmol m -2 s -1 , i.e. values that were well within the light intensities required to sustain the optimal growth of filaments. The formation of the autumn and winter blooms was triggered by the cooling of surface waters and the deepening of the mixed layer, which, eroding the metalimnion, entrained the filaments of P. rubescens in the surface mixed layers. The formation of the surface blooms was associated with the presence of high amounts of microcystins, which in a few occasions reached concentrations between 10 and 22 µg L -1 , posing potential problems for the exploitation of water resources.
