The Sole of Siwaschsees is extremely salty and has a pink color. That the Sole of microalgae Dunaliella Salina (it is the largest plant in the world carotene) owe.


The microalgae Dunaliella Salina is a plant-like organism that lives in the salty water. Dunaliella salina is known for its antioxidant effect, as it produces more than 30 different carotenoids.


Only a few organisms can survive in the brine with the extremely high salt concentration and under extreme environmental conditions (light irradiation, heat, nutrient deficiency). To survive, these organisms produce large amounts of carotenoids. Above all, a high concentration of β-carotene is obtained pink (beta-carotene).


The beta-carotene is one of the Carotinodien, the precursors of vitamin A and is also referred to as "pro-vitamin A". In the body, the vitamin A is produced from beta-carotene as needed. Here, the beta-carotene has a certain depot form and there is no risk of overdose, as is the case with the vitamin A.


The beta-carotene is an antioxidant, supports the function of the skin in the defense against free radicals and makes the skin resistant to irritation. Beta-carotene also acts on the pigmentation of the skin and activates the tanning process while protecting against UV light ..


Worldwide, the microalgae Dunaliella Salina is very widely used in the cosmetic and dietary supplement industry.

Slowly a wider blanket of salt forming on the shores of the Sivash.

By reducing the amount of water in the summer, the salinity increases in the remaining water bodies to continue and there is a brine with a salt concentration of about 30% or more (natural saturation) formed and reached a mineral content of 350 mg / l.

 Salt crusts on plants
If the brine is saturated deposits from the salt on plants.
