Screening acute cytotoxicity biomarkers using a microalga as test organism
(Elsevier, 2012-12)
The present study checked the suitability of the integration of flow cytometry (FCM) as technique and a freshwater microalga (Chlamydomonas moewusii) as cell system model for ecotoxicological studies, looking for sensitive ...
Atrazine induced changes in elemental and biochemical composition and nitrate reductase activity in Chlamydomonas reinhardtii
(Taylor & Francis, 2016)
Herbicides play an important role in agricultural practices but the introduction of these compounds into the aquatic environment can have severe consequences for non-target organisms such as microalgae. The ubiquitous green ...
Flow cytometric analysis of the encystment process induced by paraquat exposure in Haematococcus pluvialis (Chlorophyceae)
(Taylor & Francis, 2011)
The freshwater microalga Haematococcus pluvialis exhibits a unique morphological response to environmental stress, accumulating carotenoid pigment during encystment. The complexity of characterizing the different cell ...
Flow cytometric assay to assess short-term effects of personal care products on the marine microalga Tetraselmis suecica
(Elsevier, 2017)
[Abstract] Large quantities of personal care products (PCPs) are used daily and many of their chemical ingredients are subsequently released into marine environments. Cultures of the marine microalga Tetraselmis suecica ...
Flow cytometric analysis to evaluate physiological alterations in herbicide-exposed Chlamydomonas moewusii cells
(Springer, 2012-03)
Investigation of herbicide toxicology in non-target aquatic primary producers such as microalgae is of great importance from an ecological point of view. In order to study the toxicity of the widely used herbicide paraquat ...
Characterization of cell response in Chlamydomonas moewusiicultures exposed to the herbicide paraquat: Induction of chlorosis
(2011-03)
[Abstract] The use of herbicides constitutes the principal method of weed control, but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as ...
Acute effects of a prooxidant herbicide on the microalga Chlamydomonas reinhardtii: Screening cytotoxicity and genotoxicity endpoints
(Elsevier, 2015-08)
Since recent evidence has demonstrated that many types of chemicals exhibit oxidative and/or genotoxic potential on living organisms, reactive oxygen species (ROS) formation and DNA damage are currently the best accepted ...
Suitability of cytotoxicity endpoints and test microalgal species to disclose the toxic effect of common aquatic pollutants
(Elsevier, 2015-04)
Pulse discharges of chemicals to aquatic environments may lead to high concentrations of them in surface waters for short periods of time, but enough to induce toxic effects on aquatic organisms; however, no many methods ...
Chlamydomonas Reinhardtii Cells Adjust the Metabolism to Maintain Viability in Response to Atrazine Stress
(Elsevier, 2015-05-19)
[Abstract] Chlamydomonas reinhardtii cells were exposed to a sublethal concentration of the widespread herbicide
atrazine for 3 and 24 h. Physiological parameters related to cellular energy status, such as cellular ...
Early alterations on photosynthesis-related parameters in Chlamydomonas reinhardtii cells exposed to atrazine: A multiple approach study
(Elsevier, 2016-06-01)
Chlamydomonas reinhardtii cells were exposed to a sublethal concentration of thewidespread herbicide atrazine
for 3 h. Physiological cellular parameters, such as chlorophyll a fluorescence and oxidative stress monitored ...
