Class III metallothioneins in response to cadmium toxicity in the marine microalga Tetraselmis suecica (Kylin) Butch.
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 metal that reduces the population growth to 50% of the control growth level is 5.8 mg/L after 96 h of exposure. In this study, class III metallothioneins were investigated for...
متن کاملSorption isotherm studies of Cd(II) ions using living cells of the marine microalga Tetraselmis suecica (Kylin) Butch.
The present work reports the use of living cells of the marine microalga Tetraselmis suecica for the biosorption of cadmium ions. For a better understanding of the biosorption characteristics, three fractions of removed cadmium (total, bioadsorbed and intracellular) were measured in the cells after 24 and 72 h of exposure to different initial cadmium concentrations (0.6-45 mg L(-1)). Both the L...
متن کاملA Voltammetric Study on the Adsorption of Cd(II) and Zn(II) on Marine Microalgae Tetraselmis gracilis (Kylin) Butcher
As capacidades de ligação de prótons e metais por células vivas da microalga Tetraselmis gracilis foram estudadas por titulação potenciométrica e voltametria de redissolução anódica, respectivamente. A ligação de Cd(II) e Zn(II) foi estudada em água do mar (pH 8,2) por adições de soluções dos cátions metálicos em soluções simples ou misturas binárias. O cálculo das concentrações dos metais cons...
متن کاملGreen synthesis of gold nanoparticles by the marine microalga Tetraselmis suecica.
The application of green-synthesis principles is one of the most impressive research fields for the production of nanoparticles. Different kinds of biological systems have been used for this purpose. In the present study, AuNPs (gold nanoparticles) were prepared within a short time period using a fresh cell extract of the marine microalga Tetraselmis suecica as a reducing agent of HAuCl4 (chlor...
متن کاملCadmium removal by living cells of the marine microalga Tetraselmis suecica.
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 after six days of exposure. The cadmium removed was proportional to the concentration of this metal in the medium and it was dependent on the time of exposure; cultures with higher cadm...
