Biomass production and astaxanthin accumulation in Haematococcus pluvialis were investigated under different light-emitting diode (LED) wavelengths. The maximum biomass (5.41 and 6.25 g dry weight/L) was obtained under the red LEDs (630 nm and 660 nm) with light intensity of 200 μmol m-2s-1 at day 7 after cultivation in mixotrophic media with modified Bold’s Basal Medium including sodium acetate. The highest astaxanthin content (31.4 mg/g dry weight biomass) was accumulated when incubated under red LEDs (630 nm) for 4 days by increasing the light intensity to 1,000 μmol m-2s-1. In these results, we propose an efficient way of cultivating H. pluvialis in mixotrophic media under red (630 nm) LEDs for maximum biomass production and then increasing the light intensity over 1,000 μmol m-2s-1 to induce a high level of astaxanthin content.
