Kinetics of biomass, residual glucose and cellular lipids of Y. lipolytica strains grown on glucose. Strains (a) 3229, (b) 3450, (c) 3472, (d) 3589 and (e) 3590 were grown on 30 g L-1 glucose as mentioned in Materials and Methods. All values are represented as Mean ± SD, determined after 3 independent experiments. Biomass (g L-1) - ▾, Lipid (g L-1) - •, Glucose res (g L-1) - ○. Inset In each graph light microscopy (left panel) and Nile red fluorescence microscopy (right panel) images of the respective Y. lipolytica strains under 100x oil immersion objective. Bar indicates 10 μm for a, c and d and 5 μm for b and e.
