Physiological response of freshwater microalga (Chlorella vulgaris) to triazine and phenylurea herbicides
(2002-09)
[Abstract]The effects of two herbicides used wide-spread, isoproturon (phenylurea) and terbutryn (triazine), on growth, dry weight, elemental composition, photosynthetic pigments and protein content, and cell volume assayed ...
Riboflavin enrichment throughout the food chain from the marine microalga Tetraselmis suecica to the rotifer Brachionus plicatilis and to White Sea Bream (Diplodus sargus) and Gilthead Sea bream (Sparus aurata) larvae
(2008-10)
[Abstract]The riboflavin enrichment of the marine microalga Tetraselmis suecica and the transfer of this vitamin to higher trophic levels of the aquatic food chain such as the rotifer Brachionus plicatilis and the larvae ...
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, ...
Alteration of photosynthesis related parameters of Chlamydomonas moewusii stressed by paraquat
(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 ...
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 ...
The herbicide paraquat induces alterations in the elemental and biochemical composition of non-target microalgal species
(2009-09)
[Abstract]Huge quantities of pesticides are dispersed in the environment, affecting non-target organisms. Since paraquat affects the photosynthetic process, the biochemical composition of affected species should be altered. ...
Removal of triazine herbicides from freshwater systems using photosynthetic microorganisms
(2006-11)
[Abstract]The uptake of the triazine herbicides, atrazine and terbutryn, was determined for two freshwater photosynthetic microorganisms, the green microalga Chlorella vulgaris and the cyanobacterium Synechococcus elongatus. ...
