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 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 ... -
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 ... -
Growth and biochemical profile of juvenile mussels (mytilus galloprovincialis Lmk) fed on different algal diets
(National Shellfisheries Association, 1994)The food value of different microalgal diets to juvenile Mytilus galloprovincialis Lmk was assessed. Three different marine microalgae species (Tetraselmis suecica, Dunaliella tertiolecta and Phaeodactylum tricornutum) ... -
Growth and biochemical variability of the marine microalga Chlorella stigmatophora in batch cultures with different salinities and nutrient gradient concentration
(Taylor & Francis Group, 1987-03-30)[Abstract] Chlorella stigmatophora was cultured under 56 different combinations of nutrient-salinity concentrations, ranging from 1 to 64 mM NaNO3 and from 0 to 35%. salinity. Optimal growth conditions for obtaining maximum ... -
Growth of the marine microalga Tetraselmis suecica in batch cultures with different salinities and nutrient concentrations
(Elsevier Science Publishers, 1984)The marine microalga Tetraselmis suecica is known for its ability to tolerate a wide range of salt concentrations. Cultures were grown under 48 different nutrient concentration-salinity conditions, ranging from 2 to 64 mM ... -
Growth, chlorophyll α and protein of the marine microalga Isochrysis galbana in batch cultures with different salinities and high nutrient concentrations
(Elsevier Science Publishers, 1985)Cultures of the marine microalga Isochrysis galbana were grown under 56 different nutrient concentration-salinity conditions, ranging from 1 to 64 mM NaNO3 and from 0 to 35‰ salinity. Salinity and nutrient concentration ... -
High yield mixotrophic cultures of the marine microalga Tetraselmis suecica (Kylin) Butcher (Prasinophyceae)
(Springer, 1992-03)The effects of three organic compounds were tested on one of the most used marine micro-algae in the aquaculture of molluscs and crustaceans, Tetraselmis suecica. Studies were made in axenic conditions with yeast extract, ... -
Improvement of growth rate and cell productivity by aeration rate in cultures of the marine microalga Dunaliella tertiolecta
(Elsevier, 1994)The effect of different aeration rates and CO2 supply regimes on mass cultures of the marine microalga Dunaiella tertiolecta was studied. Eight aeration rates in the range 0-6.51 litres of air min-1 litre of culture-1 were ... -
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 ... -
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 ... -
Long-chain class III metallothioneins as a mechanism of cadmium tolerance in the marine diatom Phaeodactylum tricornutum Bohlin
(1997-11)Cadmium tolerance of the marine diatom Phaeodactylum tricornutum Bohlin was studied. P. tricornutum growth was significantly reduced by cadmium concentrations of 5 mg l−1 or higher. The EC50 value was 22.39 mg l−1 of cadmium ... -
Marine microalgae as a potential source of minerals in fish diets
(Elsevier, 1986-01)The incorporation of powdered marine microalgae in fish diets can substitute, at least in part, for the addition of minerals to the diet. In diets for freshwater fishes, the incorporation of 33% of powdered marine microalgae ... -
Marine microalgae as a potential source of single cell protein (SCP)
(Springer, 1985-12)[Abstract] The marine microalgae Tetraselmis suecica, Isochrysis galbana, Dunaliella tertiolecta and Chlorella stigmatophora are good biological sources of single cell protein (SCP). Protein content accounts for 39.12%–54.20% ... -
