Microalgae

Small Organisms With Great Potential


Thanks to their ingredients, microalgae are a highly-demanded raw material in many sectors. They are extremely rich in omega-3 and omega-6 fatty acids, vitamin B12, as well as protein. Also, they contain pigments of high economic value.

Anwendungsgebiete

Land-Based Aquaculture
Microalgae are essential part of fish, shrimps, and mussels farming. Since they are the only nutrition source of all marine larvae, aquaculture facilities cultivate large amounts of microalgae at their facilities. The demand is constantly increasing as the world population is growing, while overfishing and ecological problems lead to a decrease of wild-caught fish.
The PhytoFence enables aquaculture facilities to install a microalgae aquaponics system and also to cultivate Dinoflagellates. This algae specie belongs to the natural feed spectrum of marine organisms but does not grow in current microalgae production system. Consequently, aquaculture farmers cannot feed them. With our system, we enable the production and feeding of Dinoflagellates.
Fish Feed
With a growing production of marine food products, the demand for fish feed also increases. Fish feed has large amount of protein, but other ingredients, such as omega 3, are also essential. To produce fish in a sustainable way, an efficient, and vegetarian source of protein as well as omega-3 are necessary. Currently, the majority of the omega-3 used in the fish feed industry comes from fish oil. For fish oil however, again fish is used. Algae are the natural resource of omega-3 for marine organisms and hence an ecological alternative to fish oil. Thanks to the high protein concentration, algae are also a prospective protein source for fish feed.
Cosmetic and Pharmaceutical Applications
Microalgae include valuable ingredients for the cosmetics and pharmaceutical industry. The most well-known example is astaxanthin, a red pigment produced by the algae Haematococcus pluvialis. It serves as high quality ß-carotene and antioxidant for skin creams for instance. Besides astaxanthin, there are various other pigments that are produced by further algae species. However, it is not possible to produce many of these algae species with state-of-the-art production systems. With the PHYTOLINC system, we enable the cultivation of many of these species and open new markets.
Food Supplement
In the food supplement sector, the two main algae species are Chlorella vulgaris and Spirulina platensis. Processed in the form of powder, pellets, or supplements for various food products, they serve as source for protein, vitamin B12, as well as omega-3 and omega-6 fatty acids. Microalgae have a very high protein concentration of up to 60% and serve as direct protein source.
In addition, the required land space per kilogram of protein is very low. While in the European Union, on the average 8 – 10 hectares of land are needed to produce 10 tons of protein from soy beans, while only 0.7 – 2.5 hectares of land are required for the same amount of protein from microalgae.

Efficient Protein Source

Microalgae have a very high protein concentration. At the same time, their water consumption is very low. Currently, 20 liters of water are needed to produce 1 kilogram of algae biomass. With our system, we reduce the water consumption further to just 2 liters!
