When it comes to astaxanthin, people involuntarily think of Haematococcus pluvialis, which is often regarded as the main algae species rich in a large amount of astaxanthin, and its astaxanthin content is usually 1.5% – 3%, and has always been regarded as the “concentrate” and the best biological source of natural astaxanthin. However, we have overlooked another kind of “red algae”, namely Dunaliella salina. Due to the lack of enzymes for synthesizing astaxanthin in the Dunaliella salina species, it cannot convert β-carotene into astaxanthin and is ignored by humans.

Some research has introduced the key enzyme gene for astaxanthin synthesis into Dunaliella salina by the gene gun transformation method, and after screening, the transformed Dunaliella salina that can synthesize astaxanthin was obtained, and its astaxanthin content was measured to be 3.71 μg/gdw. And after the successful synthesis of astaxanthin in Dunaliella salina, its astaxanthin content is higher than that of Haematococcus pluvialis.

Dunaliella is like a tiny work of art sketched by nature with delicate strokes. Its form is delicate and unique, and its small body presents a round and plump shape, as if it were a mini green pearl. Under the microscope, its simple and wonderful structure can be clearly seen, full of the beauty of the flexibility of life.

Dunaliella belongs to a kind of green algae, and it has strong salt tolerance and can thrive in a high salt environment. This unique characteristic enables it to survive and reproduce in some special water areas. Moreover, Dunaliella is rich in β-carotene, which has many benefits for the human body, such as antioxidation and eye protection. At the same time, it also contains rich nutrients such as proteins, vitamins and minerals, which play an important role in maintaining the normal physiological functions of the human body.

From the perspective of nutritional value, Dunaliella is a rich treasure trove. It is rich in a variety of nutrients beneficial to the human body, injecting vitality and health into life. These precious ingredients are like mysterious gifts bestowed by nature, nourishing our body and mind.

In the field of scientific research, Dunaliella also has an important position. It provides scientists with endless exploration space and becomes a key to unlock the mystery of life. Through in-depth research on Dunaliella, we can understand the operating mechanism and wonders of life more deeply.

Dunaliella, it is a gift of nature, a small but shining existence. It makes us sigh the uncanny workmanship of nature, and also makes us full of awe and love for the diversity and magic of life. Let us cherish this precious gift from nature and jointly appreciate the wonderful world presented by Dunaliella.
