Abstract

The effects of different kinds of artificial light source and light quality on two species of microalgae (Chlorella vulgaris and Dunaliella salina) of high resistance of acid, heat and CO₂ concentration were investigated in this research, 9 light qualities (LR, LB, LW, FL, LR+LB, LW+LR, LW+LB, FW+LR and FW+LB) were set up with 4 kinds of light source (LED-Red (LR), LED-Blue (LB), LED-White (LW)) and Fluorescent lamp white (FW) to cultivate microalgae, while biological parameters and P-I curves were measured and drawn to evaluate the effect of light source and light quality on growth characteristics of microalgae, respectively. Results showed that ^-_P_m of two microalgae were observed under the illumination of LED-W when 4 kinds of light source were employed. At the end of cultivation, maximum biomass of C. vulgaris were observed under the illumination of light qualities LW+LB, which were 0.19 g•L^-1, however, the highest growth rate was obtained under the illumination of light quality LB by D. salina, which was 1.5 times as much as that in LR treatment. In addition, the nonuniformity between photosynthetic pigments content and μ along with the changed light quality indicated that the variation of photosynthetic pigments content may not be the main cause of microalgae growth regulated by light quality, while the light absorption of living cells might be the primary reason affecting the growth of microalgae.
