  1. Representation of biomass (∆X) and lipid yields (∆P), coefficient of biomass yield to sugar consumption (YX/S, g/g), coefficient of lipid yield to sugar consumption (YP/S, g/g), coefficient of lipid yield to biomass yield (YP/X, g/g), and rate of sugar consumption (RS, g.L−1.h−1). Fermentations conducted at pH 4.5 and 33.6 °C, with initial sugar concentration in hydrolyzed whey permeate at 51.2 g/L. Data is the mean ± standard deviation of three replicates
