Table 4.

β-Carotene production kinetic parameters (modified Logistic model) during B. trispora growth in non-sterile lye and washing waters after enrichment with nutrients as well as in synthetic medium (fermentation time: 6 days) ¹.

Fermentation Substrate	β-Carotene Production Parameters ²			Goodness of Fit
Fermentation Substrate	P_m (mg/L Broth)	R_m (1/h)	λ_CR (h)	R ²
Nutrient-enriched lye	83.032 ^a ± 0.798	2.018 ^a ± 0.069	47.320 ^a ± 0.524	0.999 ^a ± 0.001
Nutrient-enriched washing waters	81.494 ^a ± 1.765	1.418 ^b ± 0.048	31.052 ^b ± 0.828	0.994 ^b ± 0.001
Synthetic medium	50.655 ^b ± 0.182	0.842 ^c ± 0.044	26.221 ^c ± 1.012	0.978 ^c ± 0.005

¹ Each value was expressed as mean ± standard deviation of three replicates. Different lowercase letters (a, b, and c) in the same column represent significant differences in values (p< 0.05). ² P_m = maximum value of β-carotene content, R_m = maximum specific β-carotene production rate, λ_CR = β-carotene production lag time.
