Introduction: Ulva lactuca

What is Ulva lactuca?

Ulva lactuca is a macroalga that belongs to the green algae. It is also known under the common names "sea lettuce" and "sea lettuce", because its shape reminds of iceberg lettuce.

What is the classification of Ulva lactuca?

Like other macroalgae, Ulva lactuca belongs to the eukaryotes as a multicellular organism. The genus Ulva counts more than 400 different species, to which also U. lactuca belongs. Ulva lactuca thus belongs to the class of Ulvophyceae, all of which are green algae.

What are the characteristics of Ulva lactuca?

The shape of Ulva lactuca is particularly striking. The flat, slightly curled thallus of the macroalga is reminiscent of leaf lettuce, which is where the common name comes from. The intense green color also contributes to this.

Where is Ulva lactuca found?

Ulva lactuca is found worldwide, except for Antarctica. However, because the genus Ulva has so many species, confusion within the genus can easily occur. Ulva lactuca grows primarily in shallow tidal waters, where it receives more sunlight than in deeper waters, giving it a distinct advantage in photosynthesis.

How is Ulva lactuca grown?

Ulva lactuca can be grown naturally on rocky substrates. More commonly, cultivation uses a technique in which ropes are placed in the sea, along which Ulva lactuca adheres and grows. The ropes are then retrieved at the end of the growing season and at the beginning of harvesting.

What is the importance of Ulva lactuca to the ecosystem?

Ulva lactuca grows very quickly at high nutrient concentrations and therefore has potential applications for bioremediation. For example, Ulva lactuca can be cultivated in high nutrient wastewater as part of an ecological aquaculture.

What are the different benefits and application purposes of Ulva lactuca?

The two main uses of Ulva lactuca are as a food and as an active ingredient in cosmetic products. In both cases, the nutrient profile, as well as the wide availability of Ulva lactuca macroalgae, is the reason it is so often used.

However, Ulva lactuca is not limited to these two industrial uses, but is also actively used as animal feed and fertilizer. Experiments are also underway to see if Ulva lactuca could be a potential source of bioenergy.

Is Ulva lactuca edible?

Ulva lactuca is edible and has been used as food for a long time, mainly in coastal regions. On the one hand, Ulva lactuca can be eaten raw as a salad and found in dishes, or on the other hand, it can be further processed in dried form as an ingredient.

What pigments are contained in Ulva lactuca?

The majority of pigments in Ulva lactuca is chlorophyll-a followed by chlorophyll-b. In addition, there are different carotenoids, which vary in concentration from location to location.

Which polysaccharides are contained in Ulva lactuca?

Ulva lactuca contains polysaccharides called "ulvans". These are heterogeneous sulfated compounds consisting of residues of glucose, galactose, mannose, rhamnose, uronic acids, arabinose and xylose.

What are the advantages of Ulva lactuca for cosmetic use?

Ulva lactuca has a remineralizing effect due to its nutrient profile and protects the skin from environmental free radicals when applied. In addition, Ulva lactuca can have an anti-inflammatory effect on the skin.

Typical applications

Ulva lactuca, also known as "sea lettuce", is a green algae that can be found almost all over the world on sea coasts.

The sea lettuce is, as the name suggests, often eaten and offered as a sea salad. But it also finds a place in pasta or seasoning mixtures.

Not only for us humans is the sea lettuce healthy, but also as an additive for animal feed, as it offers a variety of micro and macro nutrients.

Because of its many trace elements and minerals Ulva lactuca is an excellent fertilizer.

What makes Ulva lactuca especially unique are the two substances heparin and aosaine that are contained in it. Heparin helps against the sagging of the skin, while aosaine strengthens and firms the skin and thus helps against the formation of wrinkles.

The liquid is usually used in the production of cosmetics and aquaristics.

This product is available in the following forms of liquid extracts: glycerin extract and water-glycerin extract.

The product is also available as powder.

Typical applications in the cosmetics industry:

Ulva lactuca is rich in sodium, potassium, aluminum, nickel, iodine, magnesium, manganese and is now an ingredient in many cosmetic and dermatological products.
It also contains calcium, phosphorus, soluble nitrogen, vitamin A, vitamin B1, vitamin C and numerous other trace elements.

Ulva lactuca has not only antibacterial and fungicidal, but also proven anti-inflammatory effects.
