Algae in Industry


So why grow algae?

Micro-algae comprise a vast group of phototrophic, unicellular organisms with an immense range of genetic diversity. They can be cultivated under a range of conditions, meaning they can grow in often difficult agro-climatic environments. In addition, they exhibit rapid growth rates and as a result of the tremendous metabolic diversity are a resource for a wide spectrum of bio-based applications and bioactive molecules.

There is great commercial value in algal products. Current markets include speciality products and neutraceuticals, including pigments, omega-3 and -6 fatty acids, vitamins and whole algae as a health food item or for inclusion in cosmetic preparations. Due to demand exceeding supply a Norwegian health product company has recently made a substantial investment in the production of natural astaxanthin from micro-algae. The high quality product is produced by Icelandic based Algalif AS with support from Iceland’s minister for industries and innovation ––media/news/invest/microalgae-production/212

The algal production company Cynotech, based in Hawaii, has been cultivating Spirulina pacifica for many years. The microscopic blue-green alga is an excellent source of easily absorbed, high quality protein combined with other valuable biomolecules. Cynotech net sales for 2016 financial year was USD 31,568,000 –

The increasing aquaculture market is particularly pertinent for the ASLEE project. In aquaculture systems, micro-algae can be used directly to nourish larvae, for example for shrimp or bivalve shellfish, alternatively it can be given indirectly via zooplankton to hatchery fish.
