Cyanobacteria and Their Toxins

Separation Science and Technology, 2019
Cyanobacteria, common inhabitants of marine water and freshwater are photosynthetic bacteria that, under appropriate conditions, have the potential to produce mass populations called blooms. Although they can be aesthetically unpleasant, they are capable

Methods to detect cyanobacteria and their toxins in the environment

Applied Microbiology and Biotechnology, 2014
Cyanobacteria blooms are since early times a cause for environmental concern because of their negative impact through the release of odors, water discoloration, and more dangerously through the release of toxic compounds (i.e. the cyanotoxins) that can affect both human and animal welfare. Surveillance of the aquatic ecosystems is therefore obligatory,

Cyanobacteria and their toxins in Guanting Reservoir of Beijing, China

Journal of Hazardous Materials, 2008
The present study investigated the cyanobacteria and one family of their toxins-microcystins (MCs) in Guanting Reservoir of Beijing, China. The dominant species in the cyanobacteria found in August and September of 2006 was Microcystis, which accounted 99% of total algal cells.

Biochemical Method for Quantitative Estimation of Cyanobacteria Toxins

, 2008
It is shown the possibility of using the model reaction with cholinesterase inhibition for qualitative and quantitative determination of Cyanobacteria toxic metabolites in natural waters and algae cells. It was established that changes of cultural medium pH may be registered by spectrophotometric method with using of bromine thymol blue indicator or by

Toxins of cyanobacteria

Molecular Nutrition & Food Research, 2006
AbstractBlue‐green algae are found in lakes, ponds, rivers and brackish waters throughout the world. In case of excessive growth such as bloom formation, these bacteria can produce inherent toxins in quantities causing toxicity in mammals, including humans. These cyanotoxins include cyclic peptides and alkaloids.

Harmful cyanobacteria-diatom/dinoflagellate blooms and their cyanotoxins in freshwaters: A nonnegligible chronic health and ecological hazard.

Water Research, 2023
Human and ecological health depends on the vitality of freshwater systems, but these are increasingly threatened by cyanotoxins released from harmful algal blooms (HABs).

Rapid analysis of peptide toxins in cyanobacteria

Journal of Chromatography A, 1988
A quick and easy-to-perform method for routine analysis of cyanobacterial (blue-green algal) peptide toxins is proposed. The toxins are analysed by means of high-performance liquid chromatography using a recently developed internal surface reversed-phase column.
