Chlorella pyrenoidosa is a species of the freshwater green algae genus Chlorella. It occurs world wide. The species name pyrenoidosa refers to the presence of a prominent pyrenoid within the Chlorella chloroplast.


Chlorella pyrenoidosa has been used medicinally as a chelatory agent, for example to extract dioxins and dioxin-like compounds from the body.[1]

Possible medicinal uses include:

The pyrenoidosa specie have been used in traditional Chinese medicine. Also, chlorella pyrenoidosa contains chlorella growth factor or chlorella extract. Chlorella growth factor contains ß 1.3 glucan.[2]

Boraas (1983) reported a mutation in a population of Chlorella pyrenoidosa kept in his lab as a food stock for a population of flagellates. Due to a malfunction of his equipment some of the flagellates got in the Chlorella's tank. This caused a mutation from unicellular to multicellular.

This algae was used in a 1961 study by Boeing to see about feasibility for the use of algae providing oxygen on space missions.[3]
