(Elsevier, 2022-09-07)[Abstract] The health concern associated with the dangers related to exposure to UV radiation has led to an increase in the use of sunscreens containing UV-filters that can reach aquatic environments and possibly affect ... -
Decrease in plasma cholesterol, triglycerides and CPK levels in rats fed on the marine microalga Dunaliella tertiolecta
(Geor Thieme Verlag, 1986)The dried marine microalga Dunaliella tertiolecta was fed to weaning albino rats for 12 days as the sole protein source at a protein level of 12% protein from casein. Plasma cholesterol, triglycerides, and CPK levels were ... -
Decrease of plasma cholesterol with the marine microalga dunaliella tertiolecta in hypercholesterolemic rats
(Applied Microbiology, Molecular and Cellular Biosciences Research Foundation (Japan), 1994)Female Sprague-Dawley rats, whose plasma cholesterol level had been previously increased, were fed on a diet including 22% biomass of the marine microalga Dunaliella tertiolecta. This diet was compared to two control diets, ... -
Disorders provoked by copper in the marine diatom Phaeodactylum tricornutum in short-time exposure asays
(Station Biologique de Roscoff, 1997)[Abstract] Copper toxicity on the marine diatom Phaeodactylwn tricomutum was assessed after 24.liours of exposure, using different parameters: growth, 14C-bicarbonate assimilation, 3H-thymidine incorporation, photosynthetic ... -
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 ... -
Early alterations on photosynthesis-related parameters in Chlamydomonas reinhardtii cells exposed to atrazine: A multiple approach study
(Elsevier, 2016-06-01)Chlamydomonas reinhardtii cells were exposed to a sublethal concentration of thewidespread herbicide atrazine for 3 h. Physiological cellular parameters, such as chlorophyll a fluorescence and oxidative stress monitored ... -
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, ... -
Effect of oil and dispersant on growth and chlorophyll a content of the marine microalga Tetraselmis Suecica
(American Society for Microbiology, 1984)[Abstract] Low hydrocarbon concentrations stimulated the growth of Tetraselmis suecica, whereas higher concentrations (200 ppm) inhibited growth. The content of chlorophyll a in this microalga was affected in a similar ... -
