Chromochloris zofingiensis is a unicellular green alga in the class Chlorophyceae, and is closely related to the model alga Chlamydomonas reinhardtii. Interest in C. zofingiensis derives in part from its ability to accumulate large amounts of triacylglycerols in cytoplasmic lipid bodies, which gives it promising commercial potential as a biofuel feedstock. Additionally, C. zofingiensis is capable of producing large quantities of high-value molecules such as the carotenoid astaxanthin, which is an antioxidant and anti-inflammatory nutraceutical beneficial to human health. Research on C. zofingiensis provides insight into the green lineage, regulation of metabolism, and the biosynthesis of astaxanthin. Previously, C. zofingiensis was placed in genera Chlorella, Muriella, and Mychonastes.
