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 ... -
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 ... -

Herrero, Concepción; Orosa García, Miguel; Abalde, Julio; Rioboo, Carmen; Cid, Ángeles (Nova Science Publishers, 2012) -
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 ... -

Comparison of the accumulation of astaxanthin in Haematococcus pluvialis and other green microalgae under N-starvation and high light conditions
Orosa García, Miguel; Valero, J. F.; Herrero, Concepción; Abalde, Julio (Springer, 2001-07)Haematococcus pluvialis gave the highest astaxanthin accumulation rate (2.7 mg l−1 day−1) and total astaxanthin content ( 22.7 mg g−1 biomass). Astaxanthin accumulation in Neochloris wimmeri, Protosiphon botryoides, ... -

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 ... -
Production and analysis of secondary carotenoids in green algae
Orosa García, Miguel; Torres, Enrique; Abalde, Julio; Fidalgo, Pablo (Springer, 2000-10)The microalgae Neochloris wimmeri, Scenedesmus vacuolatus, Scotiellopsis oocystiformis, Chlorella zofingiensis and Protosiphon botryoides were grown under secondary carotenoid inductive conditions. The results indicate ...
