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...

With the depletion of global fish stocks, caused by high demand and effective fishing techniques, alternative sources for long chain omega-3 fatty acids are required for human nutrition and aquaculture feeds. Recent research has focused on land-based cultivation of microalgae, the primary producers of omega-3 fatty acids in the marine food web. The effect of salinity on fatty acids and related ...

Powdered biomass of Nannochloropsis sp. and Tetraselmis were used as innovative ingredients in wheat tortillas at flour substitution levels 0.5–3.0%. Incorporation microalgae into the tortilla formulations led to increased protein fat content. The content phenolic carotenoids was also higher microalgae-enriched tortillas, especially for those enriched a level 3.0%. Not only but antioxidant capa...

Reduced grazing on harmful algal bloom species has been attributed to both the feeding deterrence and toxicity of the algae. Both toxic and deterrent effects of dinoflagellates of the genus Alexandrium, which contain toxins that cause paralytic shellfish poisoning, have been reported on different copepod species. We examined how toxin-containing Alexandrium fundyense affected ingestion rates of...

As the periodic emission of light pulses by emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing regime was tested on and biochemical composition microalgae Nannochloropsis gaditana, Koliella antarctica Tetraselmis chui. At low frequencies (e.g., 5 50 Hz, Duty cycle = 0.05), a strain-dependent inhibition an accumulation protein, poly...

Algae are plant organisms that produce organic molecules in the aquatic environment and absorb carbon. Since algae photosynthetic organisms, they give oxygen to environment. Algae, one of most important living resources seas, used many fields such as food, agriculture, cosmetics, medicine, pharmacy, industry also a biofuel source thanks metabolites store cell. In study carried out determine eff...
