Table 2 Comparison of lipid production by R. toruloidesCBS14 in batch and fed-batch cultivation

From: Lipid production in batch and fed-batch cultures of Rhodosporidium toruloidesfrom 5 and 6 carbon carbohydrates

Carbon C/N in batch C/N in feed Lipid production rate (g L−1 h−1) Yield lipid on carbohydrate (g g−1) Lipid content (% DW)
Glucose (65 g L−1) 65 no feed 0.21 0.18 50
65 C/N 65 0.16 0.13 50
65 C/N 65 (pulsed) 0.18 0.15 47
80 C/N 80 0.20 0.15 61
40 no N in feed 0.21 0.22 75
Glucose, xylose, arabinose (6:55:8) 65 no feed 0.08 0.10 31
65 C/N 65 0.08 0.08 38
80 C/N 80 0.07 0.06 31
40 no N in feed 0.15 0.07 58
  1. Lipid production rate, yield and percent dry weight were determined at the time of maximum total lipid produced (g L−1, see Figure 2). Carbon was provided as glucose or a mixture of glucose, xylose and arabinose (6:55:8) and (NH4)2SO4 was provided as nitrogen. Cultures were grown in defined medium at pH 4.0, 30°C, 900 rpm, 1.2 vvm aeration.
