Table 3.
Cell biomass and lipid content of Y. lipolytica obese and obese-gsy1Δ-LPAAT2 strains cultured on 20 g L−1 glucose, or on 20 g L−1 glucose +10 g L−1 palm oil in nitrogen-limited media. The values are means ± SD of measurements made on three separate cultures for each genotype. * denote values significantly (P < 0.05) different from obese and # from glucose (Student's t-tests).
