Bioactivities of the Hydrous Ethanol Extract From Marine Green Alga Chlamydomonas Sp. W80

Abstract

For the simultaneous productions of bioenergy and high value coproducts by green algae, the 50% ethanol extract of the marine green alga Chlamydomonas sp. W80, which is a potential hydrogen-producing algal strain, was examined for various bioactivities, such as antioxidant, anti-inflammatory, anti-aging, hair growth promotion, immune stimulatory and skin lightning. The skin lightning effect of the extract was found with three assay methods; anti-melanin formation, inhibition of endothelin-1 (ET-1) and stem cell factor (SCF) productions. The hair growth promotion effect was also found with two assay methods; dermal papilla cells propagation and inhibition of 5a-reductase.
