Abstract
Lutein has attracted attention because of its beneficial roles, including alleviating cardiovascular diseases. We compared lutein production of diverse indigenous algal candidates, and selected Parachlorella sp. JD-076 as a lutein producer. The strain was cultivated under different types of photo-bioreactors (PBRs). Maximal growth was obtained from the tubular type with 2.7-fold higher dry cell weight (DCW) than in the cylindrical type. To optimize lutein production, Parachlorella sp. was exposed to various levels of illumination (100-1000â¯Î¼molâ¯mâ2â¯sâ1) and combinations of glucose and CO2 in the tubular-type PBR. High-light intensity efficiently increased DCW and lutein productivity in an intensity-dependent manner, and 5% CO2 resulted in the maximum biomass and lutein productivity compared to that of other conditions, with 2.1â¯gâ¯Lâ1â¯dayâ1 and 25â¯mgâ¯Lâ1â¯dayâ1, respectively. We speculated that the strain Parachlorella sp. JD-076 will provide a cost-effective lutein bioprocess via regulation of illumination and CO2 supply.
