Haematococcus pluvialis - Fresh-water microalgae
Haematococcus pluvialis is a freshwater microalga belonging to family Chlamydomonadaceae. Strains of the alga extend across habitats ranging from the African lakes to the Arctic snow fields. Typical habitats are ephemeral ponds and rainwater pools, for example, rock pools in the Stockholm archipelago.
Under favorable conditions, the motile, green cells of Haematococcus pluvialis thrive, reproducing primarly by other unfavorable conditions. The cells enter a resting state and become spores with thick cell walls. When transforming into this spore phase, these algae not only store fats as an energy source, but also begin producing and accumulating astaxanthin.
Astaxanthin acts like a force field that protects the nuclear DNA and cell content from oxidation and UVA radiation. The encapsulated form of the alga is called an aplanospore and in this form. the alga can survive for long periods, even under harsh conditions.
