Light Influences the Growth, Pigment Synthesis, Photosynthesis Capacity, and Antioxidant Activities in Scenedesmus falcatus

Table 2

Carotenoid content in S. falcatus (KU.B1) grown under light at 100, 500, and 1000 μmol photons m⁻²·s⁻¹.

Light intensity (μmol photons m^−2·s^−1)	Lutein (mg/g sample)	Canthaxanthin (mg/g sample)	Beta-carotene (mg/g sample)
100	23.20 ± 0.61^a	10.38 ± 0.19^a	799.17 ± 22.73^b
500	25.97 ± 0.42^b	19.92 ± 0.23^b	599.47 ± 2.00^a
1000	34.56 ± 0.19^c	24.00 ± 0.38^c	919.83 ± 26.33^c

Data are presented as mean ± standard deviation (SD) (n = 3). Different alphabets indicate significant differences (a–c) within the same column at .
