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 ...
The herbicide paraquat induces alterations in the elemental and biochemical composition of non-target microalgal species
(2009-09)
[Abstract]Huge quantities of pesticides are dispersed in the environment, affecting non-target organisms. Since paraquat affects the photosynthetic process, the biochemical composition of affected species should be altered. ...
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 ...
Toxic action of copper on the membrane system of a marine diatom measured by flow cytometry
(WILEY-Liss, 1996-09)
Flow cytometric measurements were used to investigate the toxic action of copper on some Phaeodactylum tricornutum membrane systems. Throughout the time of metal exposure, the percentage of viable cells decreased as copper ...
Removal of triazine herbicides from freshwater systems using photosynthetic microorganisms
(2006-11)
[Abstract]The uptake of the triazine herbicides, atrazine and terbutryn, was determined for two freshwater photosynthetic microorganisms, the green microalga Chlorella vulgaris and the cyanobacterium Synechococcus elongatus. ...
Microalgal Bioassays as a Test of Pesticide Photodegradation Efficiency in Water
(Springer, 2001-08)
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 ...
Cell proliferation alterations in Chlorella cells under stress conditions
(2009-09)
[Abstract]Very little is known about growth and proliferation in relation to the cell cycle regulation of algae. The lack of knowledge is even greater when referring to the potential toxic effects of pollutants on microalgal ...
