Use of the Comet Assay to Evaluate Pesticide Toxicity on Non-Target Microalgae
(Nova Science Publishers, 2009)
Aquatic environments are often contaminated with numerous organic and inorganic compounds. More than 90% of the applied load of pesticides is dispersed in the environment, reaching non-target species of these aquatic ...
A capillary zone electrophoresis for determination of thiolic peptides in biological samples
(WILEY-VCH Verlag, 2009-06)
A new method to improve the analyses of thiolic peptides (cysteine, γGlu-Cys, glutathione, phytochelatins and desglycyl-phytochelatins) derivatized with monobromobimane (mBrB) in complex biological samples by CZE is ...
Comparison of the accumulation of astaxanthin in Haematococcus pluvialis and other green microalgae under N-starvation and high light conditions
(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, ...
Carotenoid accumulation in Haematococcus pluvialis in mixotrophic growth
(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 ...
Capillary zone electrophoresis for analysis of phytochelatins and other thiol peptides in complex biological samples derivatized with monobromobimane
(Wiley, 2005-02)
A new method to improve the analysis of phytochelatins and their precursors (cysteine, γ-Glu-Cys, and glutathione) derivatized with monobromobimane (mBrB) in complex biological samples by capillary zone electrophoresis is ...
Comparison of the sensitivity of different toxicity test endpoints in a microalga exposed to the herbicide paraquat
(2009-02)
[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 microalgae. ...
Class III metallothioneins in response to cadmium toxicity in the marine microalga Tetraselmis suecica (Kylin) Butch
(Wiley, 2001-09)
Microalgae are one of the most important organisms in our ecosystems being seriously affected by metal pollution. However, the microalgae Tetraselmis suecica (Kylin) Butch is tolerant to cadmium; the concentration of this ...
Analysis and enhancement of astaxanthin accumulation in Haematococcus pluvialis
(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 ...
Composition and production of thiol constituents induced by cadmium in the marine microalga Tetraselmis suecica
(Wiley, 2006-01)
Time course of intracellular levels of different thiols (phytochelatins, desglycyl-phytochelatins, glutathione, γ-glutamylcysteine [γ-Glu-Cys], and cysteine) were studied in the microalga Tetraselmis suecica exposed to ...
Variations in planktonic bacterial biomass and production, and phytoplankton blooms off A Coruña (NW Spain)
(CSIC, 2003)
[Abstract] Bacterial abundance, biomass and heterotrophic activity, along with hydrographic and phytoplankton variables,
were measured from February 1998 to September 1999 at two coastal stations off A Coruña (Galicia, ...
