Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention given to other classes, such as neurotoxins (e.g., anatoxin-a) cytotoxins cylindrospermopsin) due their potency. Most studies examine relationship between individual toxin variants factors, nutrients, temperature light. In summer 2015, we collected samples across...
Abstract To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across Mediterranean, Continental, Boreal climatic zones European continent. Multilinear regression models tested on this snapshot mostly eutrophic (median total phosphorus [TP] = 0.06 nitrogen [TN] 0.7 mg L −1 ), its subsets (2 depth types 3 zones), show that light climate stratification strength were most significant explanatory variables for...
Spirulina, a cyanobacterium widely used as food supplement due to its high nutrient value, contains volatile organic compounds (VOCs). It is crucial assess the presence of VOCs in commercial spirulina products, they could influence sensory quality, various processes, and technological aspects. In this study, profiles seventeen supplements were determined using headspace solid-phase microextraction (HS-SPME), coupled with gas chromatography-mass spectrometry (GC-MS). The identification was...
Toxic cyanobacteria occur in Greek surface water bodies. However, studies on the occurrence of cyanotoxins (CTs) are often limited to mainly microcystins (MCs), with use screening methods, such as ELISA, that not conclusive chemical structure CT variants and can be subject false positive results. A multi-lake survey Greece (14 lakes) was conducted biomass, targeted a wide range multi-class CTs including MCs, nodularin-R (NOD), cylindrospermopsin (CYN), anatoxin-a (ANA-a) saxitoxins (STXs),...
Cyanobacteria can reach high densities in eutrophic lakes, which may cause problems due to their potential toxin production. Several methods are use prevent, control or mitigate harmful cyanobacterial blooms. Treatment of blooms with low concentrations hydrogen peroxide (H2O2) is a promising emergency method. However, effects H2O2 on cyanobacteria, eukaryotic phytoplankton and zooplankton have mainly been studied controlled cultures mesocosm experiments, while much less known about the...
Microcystin-LR (MC-LR) is the most common and toxic variant of group microcystins (MCs) produced during formation harmful cyanobacterial blooms. Geosmin (GSM) 2-methylisoborneol (MIB) may also be blooms can taint water causing undesirable taste odor. The photocatalytic degradation MC-LR, GSM, MIB in under both UV-A solar light presence reduced graphene oxide–TiO2 composite (GO–TiO2) was studied. Two commercially available TiO2 materials (Degussa P25 Kronos) a reference material prepared...
This review aims to summarise the outcomes of some recent European research concerning toxic cyanobacteria and cyanotoxins, with an emphasis on developments within framework CYANOCOST Action (COST ES1105, Cyanobacterial Blooms Toxins in Water Resources: Occurrence, Impacts Management). State art management capabilities Europe have benefitted from input pure applied life sciences, human animal health sectors, water engineers, economists planners. Many these professional groups been brought...
Exposure to β-N-methylamino-l-alanine (BMAA) might be linked the incidence of amyotrophic lateral sclerosis, Alzheimer's disease and Parkinson's disease. Analytical chemistry plays a crucial role in determining human BMAA exposure associated health risk, but performance various analytical methods currently employed is rarely compared. A CYANOCOST initiated workshop was organized aimed at training scientists analysis, creating mutual understanding paving way towards interlaboratory comparison...
Abstract Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers numerous services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution climate-change induced stressors, like poor transparency, increased water temperature enhanced stratification....
Cyanobacteria are a diverse group of photosynthetic Gram-negative bacteria that produce an array secondary compounds with selective bioactivity against broad spectrum organisms and cell lines. In this study, 29 strains isolated from freshwaters in Greece were classified using polyphasic approach assigned to Chroococcales, Synechococcales, Nostocales, representing 11 genera 17 taxa. There good agreements between 16S ribosomal RNA (rRNA)–cpcBA–internal genetic spacer (IGS) characterization...
