Tetraselmis cordiformis

Tetraselmis cordiformis is a species of unicellular green microalgae belonging to the Chlorodendraceae family. These motile organisms are characterized by four flagella, which facilitate their movement in marine environments. As a highly productive species, it has become a cornerstone in industrial phycology for both research and commercial biomass production.

The organism naturally inhabits diverse marine and estuarine ecosystems globally. It is recognized for its high environmental plasticity, allowing it to thrive in varying salinity levels and temperature regimes. In cultivation settings, it is typically managed in photobioreactors or open pond systems, where environmental factors are strictly regulated to maximize yield.

Botanically, Tetraselmis cordiformis is distinguished by a thick cell wall composed of organic scales. Its biological profile is rich in essential nutrients, including high-quality proteins, lipids, and vitamins. The ability to store significant amounts of polyunsaturated fatty acids makes it a highly sought-after component for nutritional supplementation in various industrial applications.

Agronomic management for this microalga requires precise control of the culture media, usually supplemented with nitrogen and phosphorus. Optimal growth occurs within a temperature range of 20°C to 25°C under controlled light exposure. Maintenance involves consistent agitation to ensure efficient gas exchange and nutrient availability, preventing cell aggregation and ensuring consistent growth rates throughout the production cycle.

The primary economic application of this microalga is in the aquaculture sector, serving as a premium feed for crustacean larvae, mollusks, and fish fry. Beyond aquaculture, it is increasingly being utilized in the cosmetics and nutraceutical industries due to its antioxidant compounds. Ongoing research also explores its potential as a sustainable raw material for the production of biofuels, driven by its capacity to accumulate storage lipids.

• Rich content of omega-3 fatty acids.
• High adaptability to various marine environments.
• Excellent food source for marine larval stages.
• Potential for large-scale carbon sequestration.
