Profiles of sugar consumption (g/L); ammoniacal nitrogen consumption (mM); biomass concentration (g/L), and lipid accumulation, estimated through fluorescence (RFU/OD unit), of P. laurentii UFV-1 cultured in SS2 culture medium containing as carbon sources: a glucose (SS2G), b xylose (SS2X), and c a mixture of glucose and xylose (70:30, % G:X) (SS2GX); at 30 °C and 200 rpm for 96 h. The C/N ratio of these media was equal to 48. d Lipid contents of P. laurentii UFV-1 measured at 48 and 96 h of growth in SS2G, SS2X and SS2GX. Equal capital letters for the same culture medium and lowercase letters for the same time of cultivation do not differ significantly from each other by Tukey's multiple comparison test (p value > 0.05). Error bars in the a–d represent the standard deviation
