Comparison of Y. lipolytica
a ZetaW (control), b ZetaB 1 (P
-BGL1), c ZetaB 2 (P
-BGL2) and d Zeta-B12 (P
-BGL2) during aerobic growth on 10 g/L cellobiose. Shown are OD600nm, optical density at 600 nm, and cellobiose concentration versus time. Each data point represents the mean of five independent experiments and the error bar indicates the standard deviation.
