The biomass and astaxanthin yield of Chlorella zofingiensis cultivated in three different media including CZ-M1, Kuhl and KM1 were investigated. Results showed that Kuhl medium was best for growth as reflected by its highest values of specific growth rate, maximum cell dry weight concentration and cell growth yield on glucose comparing with the other media. However, its astaxanthin production was the lowest. KM1 exhibited the highest astaxanthin production both on a per dry cell weight and a per volume basis. Higher biomass (up to 8.99g•L-1 cell dry weight concentration) and astaxanthin levels (up to 20.1mg•L-1 and 2.24mg•g-1) in glucose-stressed Chlorella zofingiensis cells growing under low light in modified KM1 medium were obtained.
