Introduction: Cystoseira humilis
What is Cystoseira humilis?
Cystoseira humilis is a species of brown algae. The species is characterized by its distinctive, bushy fronds, which can grow up to 50 centimeters in length.
The species is an important ecological resource, providing habitat and food for a variety of marine organisms, including invertebrates and fish. It is also believed to play a role in regulating the nutrient and carbon cycles in coastal ecosystems, and may help to mitigate the impacts of ocean acidification and other environmental stressors.
Where does Cystoseira humilis grow?
Cystoseira humilis is a species of brown algae that is found in the Mediterranean Sea, from the coasts of Spain and Portugal to the eastern Mediterranean. The species is typically found in the shallow subtidal zone, where it forms dense stands on rocky substrates, including boulders, bedrock, and pebble beaches.
Cystoseira humilis is well adapted to the challenging conditions of the intertidal zone, and is able to withstand exposure to air and drying out during low tide. The species is able to attach itself to rocky substrates using a holdfast, which allows it to withstand the strong currents and wave action in its habitat. It is typically found in areas with moderate to high wave exposure, where it is able to grow and reproduce successfully.
For which application is Cystoseira humilis being used for?
Cystoseira humilis has a long history of use in traditional Mediterranean cultures, where it has been used for a variety of medicinal and culinary purposes. In recent years, there has been growing interest in the potential industrial applications of Cystoseira humilis and other brown algae species, due to their high content of bioactive compounds, such as polysaccharides and polyphenols.
One of the most promising applications of Cystoseira humilis and other brown algae species is in the development of functional foods and dietary supplements. The species is rich in dietary fiber and other bioactive compounds. In addition, the polysaccharides found in Cystoseira humilis may have potential applications in the development of prebiotic and probiotic supplements[3].
Cystoseira humilis and other brown algae species are also being studied for their potential use in the cosmetic industry, due to their high content of polysaccharides and other bioactive compounds. These compounds may have beneficial effects on skin health, including moisturizing, anti-aging, and anti-inflammatory properties. In addition, the species' natural pigments can be used to develop natural dyes for textiles and other materials[5].
Typical applications: Cystoseira humilis
Typical applications
The macroalga Cystoseira humilis belongs to the brown algae and is found, among other places, on the coasts of Europe.
Due to its interesting profile of ingredients, Cystoseira humilis is particularly relevant for the production of natural cosmetics. Cystoseira humilis has a high content of polyunsaturated fatty acids, antioxidants as well as antimicrobial properties[4, 5, 6].
Due to its seasonality, the macroalga Cystoseira humilis is usually abundantly available in the months of March to July.
This product is available in the form of Cystoseira humilis whole dried algae.
Typical applications in the cosmetics industry:
Cystoseira humilis can be used as an antioxidant in cosmetics and protects the skin from environmental influences. It also has an anti-inflammatory effect and can promote the recovery process of the skin[6].
Cystoseira humilis is rich in bioactive substances, which have a moisturizing effect on the skin. The macroalgae provides anti-aging properties, as it increases the firmness of the skin due to the deeper hydration[4, 5, 6].
