Appearance of Planktothrix rubescens Bloom with [D-Asp3, Mdha7]MC–RR in Gravel Pit Pond of a Shallow Lake-Dominated Area [PDF]

open access: yes, 2013
Blooms of toxic cyanobacteria are well-known phenomena in many regions of the world. Microcystin (MC), the most frequent cyanobacterial toxin, is produced by entirely different cyanobacteria, including unicellular, multicellular filamentous, heterocytic,

A Multiplex Analysis of Potentially Toxic Cyanobacteria in Lake Winnipeg during the 2013 Bloom Season

open access: yesToxins, 2019
Lake Winnipeg (Manitoba, Canada), the world’s 12th largest lake by area, is host to yearly cyanobacterial harmful algal blooms (cHABs) dominated by Aphanizomenon and Dolichospermum.

Evolution and detection of cyanobacterial hepatotoxin synthetase genes [PDF]

open access: yes, 2007
Mass occurrences (blooms) of cyanobacteria are common in aquatic environments worldwide. These blooms are often toxic, due to the presence of hepatotoxins or neurotoxins. The most common cyanobacterial toxins are hepatotoxins: microcystins and nodularins.

Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

open access: yesEcohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

CYANO RT-Microarray: A Novel Tool to Detect Gene Expression in Cyanobacteria [PDF]

open access: yes, 2018
EU μAQUA made early warning systems for freshwater pathogens and toxins. Barcodes for each cyanobacterial toxin gene published before 2011 were designed and used in a microarray format to capture messenger RNA to detect toxin gene expression at early ...

Avaliação da influência da intensidade de luz na expressão do gene mcyA e na produção de microcistina em Microcystis aeruginosa e Planktothrix agardhii [PDF]

open access: yes, 2015
As cianobactérias são frequentemente associadas à produção de toxinas, nomeadamente microcistinas. A sua síntese é não ribossomal, e acontece utilizando complexos multienzimáticos (genes mcy).

Specific Gene Loci of Clinical Pseudomonas putida Isolates [PDF]

open access: yes, 2016
Pseudomonas putida are ubiquitous inhabitants of soils and clinical isolates of this species have been seldom described. Clinical isolates show significant variability in their ability to cause damage to hosts because some of them are able to modulate ...

Successful isolation and cultivation of Cylindrospermopsis raciborskii strains isolated from finished drinking water samples [PDF]

open access: yes, 2019
This work presents the successful establishment of Cylindrospermosis raciborskii cultures isolated from water samples collected at the exit point of Water Treatment Plant (WTP). An intense bloom dominated by filamentous cyanobacteria (Aphanizomenon spp.,

The Microbiota of Recreational Freshwaters and the Implications for Environmental and Public Health

open access: yesFrontiers in Microbiology, 2016
The microbial communities in recreational freshwaters play important roles in both environmental and public health perspectives. In this study, the bacterial community structure and its associations with freshwater environments were investigated by ...
