Dunaliella Salina is a microalga that contains an elevated proportion of carotenoids. This makes it an extraordinary source of antioxidants that are beneficial for the human body. Moreover, it contains a high proportion of vitamins that are essential to protect the skin against damages.
During the last few years, it has become very popular in the cosmetic industry. Since it is found in just a few locations, not too many people can tell exactly how it is. Its special features, properties, and survival needs provide it with a special physiognomy and appearance that are worthy of analysis.
Where can you find Dunaliella Salina?
This alga is found in seas or lakes with a high proportion of salt. Some of them include the Dead Sea between Israel and Jordan, the Gulf of Thailand, Sambhar Salt Lake of Rajasthan, India, Lake Hillier in the South Coast of Western Australia, and salt mines around the world. It is an extremophile specimen because it is able to survive in extremely harsh conditions. In this case, it is about extremely salty lakes and seas that can reach from 3 to 6 times saltier than the average sea.
And D. Salina not only survives there but thrives! Among the reasons, Dunaliella Salina doesn't have a cell wall. Instead, it has a membrane that is thin and fully malleable. Also, it produces more glycerol that can reach up to 50% of its intracellular capacity. This is how it can balance the pressure it receives from the salt.
The special look of Dunaliella Salina
Although Dunaliella Salina belongs to the family of green algae, it is not the color of it. In fact, its color is the signature of this species as it is mostly pink. Sometimes can be found in the degradation of red or orange colors too. The reason is the content of high levels of carotenoids. It is the same pigment that we can find in veggies like carrots and is responsible for turning those fruits into orange, yellow, or red colors. In addition, Carotenoids also contribute to the strength of this algae and protect it from the high and long-term exposure to sun rays.
The size may vary and it may go from 5 to 25 microns in length. The width may start at 3 microns and reach up to 13 microns or micrometers.
Externally, the D. Salina has a pear shape with 2 flagella of the same length on the upper side. Internally, it has a cup-shaped chloroplast that is in charge of accumulating the long provision of carotenoids.
The future of Dunaliella Salina
Due to the potential use of the components of Dunaliella, its future in the market is bright. Currently, the main commercial producer and exporter in the world of Dunaliella Salina is Australia. This location produces it naturally but it also cultivates it to increase its production. Its commercialization started in 1960 to leverage its pigments. But nowadays it is becoming more popular in the cosmetic and health industry. The extraordinary content of carotenoids makes it especially beneficial.
