Résumé traduit : Outre la contamination anthropique, les environnements d'eau douce peuvent également être affectés par la présence de toxines naturelles. Les mycotoxines, les toxines végétales et les cyanotoxines sont les groupes les plus importants qui peuvent être trouvés dans le système aquatique. Cependant, jusqu'à présent, seules les cyanotoxines ont été étudiées plus attentivement. Dans le présent travail, un flux de travail unique pour l'évaluation des toxines naturelles dans les eaux, basé sur le dépistage suspect et le dépistage cible d'un groupe sélectionné de toxines est présenté. Les résultats de la quantification de ces composés ont montré des concentrations inférieures à 1 μg / L dans tous les cas, ce qui est considéré comme sûr selon la législation en vigueur. Cette approche de dépistage suspect permet une évaluation plus complète des toxines naturelles dans les eaux naturelles. – guatemalt
Introduction The occurrence of natural toxins in the surface and drinking water reservoirs is a problem of increasing concern for water producers and environmental scientists.
Natural toxins are secondary metabolites produced by a multitude of organisms and especially by fungi (fungal toxins or mycotoxins), plants (phytotoxins), bacteria and algae. Natural toxins are naturally synthesized by living organisms and it has been hypothesised that defence or predation mechanisms can be some of the factors ruling their production . The release of natural toxins into the environment, and in particular their occurrence in surface waters, can constitute a hazard for human health due of possible ingestion and/or recreational and bathing activities [2,3]. Several legislations have been implemented around the world.
The availability of high-resolution mass spectrometry techniques (HRMS) opened a new window for the detection of low molecular weight compounds, such as natural toxins. 2. 2.1. 3. WATER 03/06/19 Analysis of Environmental Factors Associated with Cyanobacterial Dominance after River Weir Installation. Following the installation of 16 weirs in South Korea’s major rivers through the Four Rivers Project (2010–2012), the water residence time increased significantly.
Accordingly, cyanobacterial blooms have occurred frequently, raising concerns regarding water use and the aquatic ecosystem health. This study analyzed the environmental factors associated with cyanobacterial dominance at four weirs on the Nakdong River through field measurements, and parametric and non-parametric data mining methods. TOXINS 26/07/19 Characterization of Cyanophages in Lake Erie: Interaction Mechanisms and Structural Damage of Toxic Cyanobacteria. Cyanophages are abundant in aquatic environments and play a critical role in bloom dynamics, including regulation of cyanobacteria growth and photosynthesis.
In this study, cyanophages from western Lake Erie water samples were screened for lytic activity against the host cell (Microcystis aeruginosa), which also originated from Lake Erie, and identified with real-time sequencing (Nanopore sequencing). M. aeruginosa was mixed with the cyanophages and their dynamic interactions were examined over two weeks using atomic force microscopy (AFM) as well as transmission electron microscopy (TEM), qPCR, phycocyanin and chlorophyll-a production, and optical absorbance measurements. The TEM images revealed a short-tailed virus (Podoviridae) in 300 nm size with unique capsid, knob-like proteins.
ROBERT GORDON UNIVERSITY (Aberdeen) - 1999 - Thèse en ligne: Purification, detection and biological effects of cyanobacterial toxins. Abstract The aesthetic beauty of a landscape is a very subjective issue: every person has their own opinions and their own idea of what beauty is.
However, all people have a common evolutionary history, and, according to the Biophilia hypothesis, a genetic predisposition to liking certain types of landscapes. It is possible that this common inheritance allows us to attempt to model scenic preference for natural landscapes. The ideal type of model for such predictions is the psychophysical preference model, integrating psychological responses to landscapes with objective measurements of quantitative and qualitative landscape variables.

Received 18th November 2019 , Accepted 20th February 2020 First published on 12th March 2020 Photosynthetic organisms are exposed to a fluctuating environment in which light intensity and quality change continuously.
Specific illumination of either photosystem (PSI or PSII) creates an energy imbalance, leading to the reduction or oxidation of the intersystem electron transport chain. This redox imbalance could trigger the formation of dangerous reactive oxygen species. Cyanobacteria, like plants and algae, have developed a mechanism to re-balance this preferential excitation of either reaction center, called state transitions. 1. Light is essential for photosynthetic organisms that harvest solar energy and convert it into chemical energy (ATP) and reducing power (NADPH). In order to efficiently use the incoming light and to avoid damage, sensing and adapting to environmental changes becomes crucial.

Introduction Cyanoprokaryotes are Gram-negative photosynthetic algae considered to have arisen approximately 3.5 billion years ago . In nature, they are found as single cell species or as colonies rapidly growing in fresh water, all types of aquatic ecosystems, and terrestrial habitats. Cyanobacteria are photosynthetic organisms, and as such, they are considered primary first-level consumers in the food chains in water ecosystems.
Blue-green algae play an important role in carbon and nitrogen balance in the biosphere . More than 90 microcystin isoforms, that are cyclic peptide cyanotoxins, have been described. Cyanotoxins have various chemical structures; thus, their toxic effects are due to different mechanisms. Along with the reports about the toxicity of cyanobacteria metabolites, there are studies describing their anticancer properties, hence, viewing them from a new perspective as novel potential sources for anticancer drug development . 2. 3. 3.1.

Abiotic factors Among the abiotic factors, nutrients, including inorganic nitrogen (N) and phosphorus (P), temperature, and light intensity, and hydrodynamic parameters of the water body (turbidity and residue time) have been reported as the most important factors in the proliferation of cyanobacteria [2, 4, 6]. The availability of nutrients such as N and P is essential for the growth of cyanobacteria. For example, field experiments by monitoring surveys of phytoplankton for 3 years (2012–2014) in Lake Erie (U.S.A.) showed that inter-annual differences in the duration, intensity, and toxicity of cyanobacterial blooms in this area were considered related to in-lake and tributary nutrient (N and P) concentrations .

WATER 31/05/20 Control of Nuisance Cyanobacteria in Drinking Water Resources Using Alternative Algae-Blocking Mats. The water intake facility of Paldangho Lake (PIF), constructed in 1988, supplies drinking water to the Seoul metropolitan area and satellite city (ca. 20 million inhabitants) in South Korea. A nuisance cyanobacterial bloom (CB) has been observed every year in the PIF. Thus, related governments have been funding the control of CBs and algal-originated materials (AOMs). In this study, an algae-blocking mat (ABM) was developed to protect against CBs and AOMs considering temperature and water depth.

Cyanobacterial blooms are the most important and best studied type of harmful algal blooms in fresh waters and brackish coastal seas. We here review how and to which extent they resist grazing by zooplankton, how zooplankton responds to cyanobacterial blooms and how these effects are further transmitted to fish. Size, toxicity and poor nutritional value are widespread mechanisms of grazing defense by cyanobacteria. In some cases, defenses are inducible, in some they are obligate. However, to some extent zooplankton overcome grazing resistance, partly after evolutionary adaptation. Cyanotoxins are also harmful to fish and may cause fish kills.

Introduction The human population of our planet is projected to reach ~9.7 billion by 2050, and majority of this increased population would be contributed by developing countries of Asia and Africa (DESA UN, 2015). This increase in global population is associated with increased demand of food security in future. To overcome this challenge, the World Health Organization has suggested a doubling of food production by 2050, while the United Nations have suggested a 50% increase in global food production by 2030.
The productivity gains resulted from the “Green Revolution” have essentially reached a plateau, and feeding the increased global population is further challenged by limited availability of agriculture land. The range of non-conventional biotechnological measures involving improvement in CO2 fixation efficiency of crop plants can be used to enhance the food productivity per hectare of agricultural land (Parry and Hawkesford, 2010; Parry et al., 2011).

Filamentous, heterocyst-forming cyanobacteria are phototrophic multicellular organisms in which N2-fixing heterocysts and CO2-fixing vegetative cells exchange regulators and nutrients. Upon nitrogen deprivation (perceived as an increase in the cellular C to N ratio), vegetative cells differentiate into heterocysts in a process that involves a specific program of gene expression and results in a heterocyst pattern consisting of two heterocysts separated by about 10 to 15 vegetative cells.
