Table 3.
Proportion of β-carotene, γ-carotene, and lycopene at the maximum carotenoid production by B. trispora grown in non-sterile lye and washing waters after enrichment with nutrients as well as in synthetic medium (fermentation time: 6 days).1.
| Fermentation Substrate | % of Total Carotenoid Content | ||
|---|---|---|---|
| β-Carotene | γ-Carotene | Lycopene | |
| Nutrient-enriched lye | 81.6 a ± 0.1 | 9.1 a ± 0.1 | 9.3 a ± 0.1 |
| Nutrient-enriched washing waters | 87.6 b ± 0.3 | 4.8 b ± 0.3 | 7.6 b ± 0.1 |
| Synthetic medium | 89.8 c ± 0.2 | 2.6 c ± 0.1 | 7.6 b ± 0.2 |
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).
