Advected cyanobacteria, algal blooms and cyanotoxins have been increasingly detected in freshwater ecosystems. This review gives an insight into the present state of knowledge on taxonomy, dynamics, toxic effects, human ecological health implications East African Community lakes. The major toxigenic microalgae lakes include Microcystis, Arthrospira, Dolichospermum, Planktolyngbya Anabaenopsis s...

This work aims to determine the profiles of cyanopeptides and anatoxin synthetized by cyanobacteria in Lithuanian part Curonian Lagoon (SE Baltic Sea) characterize their spatial temporal patterns this ecosystem. Cyanometabolites were analysed a LC-MS/MS system coupled hybrid triple quadrupole/linear ion trap mass spectrometer. During investigation period (2013–2017), 10 microcystins, nodularin,...

Abstract Cyanobacterial blooms in drinking water supply affect its quality, which ultimately impacts ecosystem and public health. Thus, this cross-sectional study was conducted to perform a preliminary on cyanotoxins via analysis of samples collected only once from two sites during the month peak algal bloom subsequently prompt comprehensive risk assessment major source, Legedadi Reservoir, Add...

Microcystins (MCs) are hepatotoxic cyanobacterial metabolites produced sporadically in aquatic environments under favorable environmental conditions. Affinity of these toxins to covalently bind with protein phosphatases poses a challenge in their detection. Lemieux oxidation to release 2-methyl-3-methoxy-4-phenylbutyric acid (MMPB), a common moiety to all MCs congeners, has been used in detecti...

Cyanobacteria are the predominant phototrophs in freshwater ecosystems of the polar regions where they commonly form extensive benthic mats. Despite their major biological role in these ecosystems, little attention has been paid to their physiology and biochemistry. An important feature of cyanobacteria from the temperate and tropical regions is the production of a large variety of toxic second...

Lichens are symbiotic associations between fungi and photosynthetic algae or cyanobacteria. Microcystins are potent toxins that are responsible for the poisoning of both humans and animals. These toxins are mainly associated with aquatic cyanobacterial blooms, but here we show that the cyanobacterial symbionts of terrestrial lichens from all over the world commonly produce microcystins. We scre...

Metacaspases are distant homologs of metazoan caspase proteases, implicated in stress response, and programmed cell death (PCD) in bacteria and phytoplankton. While the few previous studies on metacaspases have relied on cultured organisms and sequenced genomes, no studies have focused on metacaspases in a natural setting. We here present data from the first microbial community-wide metacaspase...
