A Comparison of the Relative Sensitivity of Structural and Functional Cellular Responses in the Alga Chlamydomonas eugametos Exposed to the Herbicide Paraquat
Franqueira, Dolores; Cid, Ángeles; Torres, Enrique; Orosa García, Miguel; Herrero, Concepción (Springer, 1999-04)The effect of the herbicide paraquat on the freshwater microalga Chlamydomonas eugametos was studied in function of different parameters such as growth, elemental composition, total lipids, and photosynthetic pigments ... -
Alteration of photosynthesis related parameters of Chlamydomonas moewusii stressed by paraquat
Cid, Ángeles; Franqueira, Dolores; Rioboo, Carmen; Prado, Raquel; Herrero, Concepción (Research Trends, 2008)Paraquat toxic action on the freshwater microalga Chlamydomonas moewusii was determined by several physiological parameters. ATP content seems to be the most sensitive parameter analyzed; it was reduced by the lowest ... -
Analysis and enhancement of astaxanthin accumulation in Haematococcus pluvialis
Orosa García, Miguel; Franqueira, Dolores; Cid, Ángeles; Abalde, Julio (Elsevier, 2005-02)The green microalga Haematococcus pluvialis was cultured with different concentrations of NaNO3 to determine the effect on cell growth and astaxanthin accumulation. The optimum nitrate concentration to obtain astaxanthin ... -
Carotenoid accumulation in Haematococcus pluvialis in mixotrophic growth
Orosa García, Miguel; Franqueira, Dolores; Cid, Ángeles; Abalde, Julio (Springer, 2001-03)The microalga Haematococcus pluvialis was cultured with NaNO3 from 0 to 1 g l−1 and optimal growth was obtained at 0.15 g l−1. Sodium acetate and malonate (from 0 to 2% w/v) enhanced the accumulation of astaxanthin three ... -
La citometría de flujo como herramienta para el estudio del efecto tóxico de diferentes contaminantes sobre microalgas
Cid, Ángeles; Franqueira, Dolores; Orosa García, Miguel; Torres, Enrique (Universidade da Coruña, 1999) -
Microalgal Bioassays as a Test of Pesticide Photodegradation Efficiency in Water
Rioboo, Carmen; Franqueira, Dolores; Canle, Moisés; Herrero, Concepción; Cid, Ángeles (Springer, 2001-08) -
Potential use of flow cytometry in toxicity studies with microalgae
Franqueira, Dolores; Orosa García, Miguel; Torres, Enrique; Herrero, Concepción; Cid, Ángeles (2000-03)[Abstract]Cytotoxic effects of aquatic pollutants on microalgae are very heterogeneous, and they are influenced by environmental conditions and the test species. Stress produced by copper or paraquat addition to the culture ...
