Table 2 Characteristics of lipid production in continuous cultures of Y. lipolytica JMY4086 grown in crude glycerol; SCFB and chemostat culturing were used

From: Lipid production by the oleaginous yeast Yarrowia lipolytica using industrial by-products under different culture conditions

  1. Mean values for biomass yield, volumetric lipid productivity (Q L ), the coefficient of lipid yield to glycerol consumption (Y L/gly), and the coefficient of lipid yield to biomass yield (Y L/X ) were calculated for the full duration of the different feeding conditions (i.e., different glycerol concentrations).
