  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.
