Sorption isotherm studies of Cd(II) ions using living cells of the marine microalga Tetraselmis suecica (Kylin) Butch
(2010-10)
[Abstract]The present work reports the use of living cells of the marine microalga Tetraselmis suecica for the biosorption of cadmium ions. For a better understanding of the biosorption characteristics, three fractions of ...
Cadmium toxicity on the freshwater microalga Chlamydomonas moewusii Gerloff: Biosynthesis of thiol compounds
(SETAC-Press (Society of Environmental Toxicology and Chemistry), 2010-09)
Cadmium (Cd) toxicity and production of different thiols (phytochelatins, glutathione, γ-Glu-Cys and cysteine) were studied in the microalga Chlamydomonas moewusii exposed to different concentrations of this metal (1, 2, ...
Astaxanthin Production in Cysts and Vegetative Cells of the Microalga Haematococcus Pluvialis Flotow

Bioremediation of oxytetracycline in seawater by living and dead biomass of the microalga Phaeodactylum tricornutum
(Elsevier, 2016)
Due to its use, a large amount of Oxytetracycline (OTC) is released into water, which has a detrimental impact on aquatic ecosystems and human health. Although there are different physicochemical methods (mainly photodegradation) ...
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 ...
Isotherm studies for the determination of Cd(II) ions removal capacity in living biomass of a microalga with high tolerance to cadmium toxicity.
(Springer Berlin Heidelberg, 2014)
The biosorption characteristics of Cd(II) ions using the living biomass of the
marine diatom Phaeodactylum tricornutum were investigated. This microalga is a
highly tolerant species to cadmium toxicity, for this reason ...
Sulphate, more than a nutrient, protects the microalga Chlamydomonas moewusii from cadmium toxicity
(Elsevier, 2014-03)
Sulphur is an essential macroelement that plays important roles in living organisms. The thiol rich sulphur compounds, such as cysteine, γ-Glu–Cys, glutathione and phytochelatins participate in the tolerance mechanisms ...
Use of Microalgae as Biological Indicators of Pollution: Looking for New Relevant Cytotoxicity Endpoints
(Nova Science Publishers, 2012)
An important amount of the applied load of pesticides enter into aquatic ecosystems from agricultural runoff or leaching and, as a consequence, have become some of the organic pollutants that appear most frequently on ...
Isobolographic analysis of the interaction between cadmium (II) and sodium sulphate: toxicological consequences
(Springer, 2016)
Sulphate is an essential nutrient for autotrophic organisms and has been shown to have important implications in certain processes of tolerance to cadmium toxicity. Sodium sulphate is the main salt of sulphate in the natural ...
