Response of the marine microalga Dunaliella tertiolecta (Chlorophyceae) to copper toxicity in short time experiments.
Heavy metals are introduced into aquatic ecosystems from industrial wastes, agricultural runoff and mining activities. The toxicity of heavy metal ions in solution to microalgae is well known. The essentiality and toxicity of heavy metals has been a subject of extensive research (Stokes 1983). From a biological point of view, heavy metals can be divided into two categories: essential and non-es...
متن کاملA PSTTLRE-form of cdc2-like gene in the marine microalga Dunaliella tertiolecta.
To understand the genetic control of algal cell division cycle that pertains to phytoplankton bloom dynamics in the sea, we cloned and analyzed a gene coding for a cyclin-dependent kinase (CDK) for the chlorophyte Dunaliella tertiolecta. The cDNA cloned, 1061 bp long, contained an open reading frame of 314 amino acids. FASTA and GAP analyses showed that this sequence was most homologous to cdc2...

متن کاملDecrease in plasma cholesterol, triglycerides and CPK levels in rats fed on the marine microalga Dunaliella tertiolecta.
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 significantly lower in animals given the microalgal diet than in the control group with values 19.12 %, 45.80%, and 43.90% lower, respectively. These results suggest that the ...
متن کاملClass 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...
