Table 4 Fitting parameters of biomass and astaxanthin production to Eq. (2) in totally-saccharified mussel waste (TSMS) containing different initial concentration of sugars

From: Mussel processing wastewater: a low-cost substrate for the production of astaxanthin by Xanthophyllomyces dendrorhous

  Biomass
X m (g/L) v m (g/L h) λ X (h) Y A/X (mg/g)
20 g/L 6.35 ± 1.03 0.977 (NS) 45.61 (NS) 3.962
40 g/L 7.41 ± 1.08 0.159 ± 0.119 30.78 ± 19.05 1.389
80 g/L 9.03 ± 1.74 0.185 ± 0.168 45.12 ± 24.91 0.355
100 g/L 9.14 ± 1.16 0.126 ± 0.060 50.77 ± 17.46 0.261
  1. Also yields of astaxanthin on biomass produced (Y A/X ) and on total sugars consumed (Y A/TS ) are shown
  2. NS non significant
