Table 1 Comparison of lipid production by R. toruloidesCBS14 at different C/N in batch culture

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

Carbon C/N Lipid production rate (g L−1 h−1) Yield lipid on carbohydrate (g g−1) Lipid content (% DW) Biomass (g L−1) Time at which maximum lipid produced (h)
Xylose 40 0.03 0.08 24 11 73
  65 0.04 0.11 36 10 85
  100 0.04 0.16 45 8 113
Glucose 40 0.08 0.10 23 9 26

  100 0.08 0.20 56 9 66
  1. Lipid production rate, yield and percent dry weight and biomass concentration were determined at the time of maximum total lipid produced. Carbon was provided as 30 g L−1 glucose or xylose 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.
