Table 1 Variation of K_a, E_a and E_s with different D. salina β-carotene contents

From: Quantitative analysis on photon numbers received per cell for triggering β-carotene accumulation in Dunaliella salina

β-carotene content (%)	Lambert–Beer model	Cornet model
β-carotene content (%)	K_a (m²·g⁻¹)	E_a (m²·g⁻¹)	E_s (m²·g⁻¹)
0.56	0.0478 ± 0.0142	0.0316 ± 0.0015	0. 718 ± 0.021
0.84	0.0493 ± 0.0132	0.0242 ± 0.0010	0.754 ± 0.017
1.21	0.0504 ± 0.0175	0.0213 ± 0.0036	0.757 ± 0.014
1.93	0.0519 ± 0.0216	0.0207 ± 0.0042	0.846 ± 0.018
2.88	0.0558 ± 0.0224	0.0196 ± 0.0026	0.883 ± 0.013
4.26	0.0587 ± 0.0144	0.0167 ± 0.0032	0.948 ± 0.060

Values are mean (± SD) of n = 3 cultivations per treatment, K_a is the extinction coefficient (m²·g⁻¹), E_a is the mass absorption coefficient (m²·g⁻¹), and E_s is the mass scattering coefficient (m²·g⁻¹)
