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

Table 1

Antioxidant activity and total phenolic compound (TPC) in S. falcatus (KU.B1) under light at 100, 500, and 1000 μmol photons m⁻²·s⁻¹.

Light intensity (μmol photons m^−2·s^−1)	DPPH (IC50)	TPC (mg of GAE/g)
100	128.50 ± 7.78^a	546.00 ± 58.26^b
500	147.00 ± 7.07^a	435.33 ± 12.59^b
1000	218.00 ± 4.24^b	230.83 ± 86.75^a

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