# Biomolecules from Microalgae and Cyanobacteria: Applications and Market Survey
## 3 Current Uses of Microalgae and Cyanobacteria in Industry
### Microalgae and Cyanobacteria as Food, Dietary Supplements, and Feed  
Microalgae and Cyanobacteria provide to the consumer an unrepeatable source of high-value compounds. Therefore, they are mostly commercialized as health products, diet supplements, functional food, and nutraceuticals in capsules, tablets, powders, pills, and syrups forms [93]. Table 4 presents different industries producing food supplements and nutraceuticals from microalgae and Cyanobacteria. _Chlorella_ (Chlorophyta) and _Arthospira/Spiurulina_ (Cyanobacteria) are the most popular genus used as diet supplements. They constitute 80% of the global microalgae food market, thanks to their composition (www.fortunebusinessinsights.com, accessed on 14 February 2021). \begin{table}

Its production and consumption are in continuous growth. In a previous assessment, the global production of dried _Spirulina_ was 12,000 tons.year\({}^{-1}\). In 2014, FAO estimated a _Spirulina_ global production of 86,000 tons [94]. According to persistence market research, over 128,000 tons of _Spirulina_ were globally consumed in 2016 (www.persistencemarketresearch.com/, accessed on 14 February 2021). Its global market size was USD 348 million in 2018 and is projected to reach USD 779 million by 2026, growing at a CAGR of 10.5% from 2019 to 2026 (www.alliedmarkresearch.com, accessed on 14 February 2021). In their report, Persistence Market Research affirmed that the powder form of _Spirulina_ was the highest form used as, in 2016, this segment represented 73.5%, and it is expected that its consumption will record a CAGR of 10.2% in the period 2019-2026. In second place, the demand for tablets and capsules will increase to a CAGR of 8.8% in the same period. By 2026, more than 250,000 tons of _Spirulina_ will be consumed globally in the production of nutraceuticals (www.persistencemarketresearch.com/, accessed on 14 February 2021).
