Haematococcus
Haematococcus pluvialis is a unicellular green microalga best known for its ability to produce astaxanthin—a deep red carotenoid that acts as a powerful cellular shield against environmental stress.

Survival strategy
Native to freshwater environments, it has a fascinating survival strategy: under normal conditions, it appears green and motile, but when exposed to stressors like high light, salinity, or nutrient depletion, it enters a dormant “red cyst” phase and floods itself with astaxanthin to protect its DNA and cell structure. This natural defense mechanism is what makes H. pluvialis so valuable.
Market Applications
Unlike Spirulina, which is prized for its protein and grows rapidly in basic water, Haematococcus has a slower growth cycle but produces one of the most powerful antioxidants found in nature: Astaxanthin. Industries from nutraceuticals to cosmetics and aquaculture have seized on this, using astaxanthin for its anti-inflammatory, anti-aging, and pigmentation properties.
Algreen Future-Proof Protocol
Algreen is driving innovation in Haematococcus pluvialis cultivation and downstream processing, delivering significant gains in yield, scalability, and cost-efficiency. Depending on the type of photobioreactor used, we can achieve Astaxanthin accumulation levels of up to 5% within just 7 days leveraging our proprietary stress protocol.
