Cadmium removal by living cells of the marine microalgaTetraselmis suecica
(2002-09)
[Abstract] Cadmium removal by living cells of the marine microalga Tetraselmis suecica was tested in cultures exposed to different cadmium concentrations (0.6, 3, 6, 15, 30 and 45 mg/l). The EC50 for growth was 7.9 mg Cd/l ...
Dunaliella salina as marine microalga highly tolerant to but a poor remover of cadmium
(2009-06)
[Abstract]Cadmium tolerance and removal in the marine microalga Dunaliella salina were studied in cultures exposed to different metal concentrations (5–120 mg Cd l−1) for 96 h. This microalga can be included in the group ...
Effect of cadmium on growth, ATP content, carbon fixation and ultrastructure in the marine diatom Phaeodactylum Tricornutum Bohlin
(Springer, 2000-01)
Cadmium toxicity to the diatom Phaeodactylum tricornutum Bohlin has been studied on the basis of the effect of this metal on growth, ATP content, 14C uptake and cellular ultrastructure. The microalga was exposed to 1, 5, ...
Production and analysis of secondary carotenoids in green algae
(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 ...
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. ...
