Figure 1. The time-course of dry cell weight, dissolved oxygen, glucose
concentration, and β-carotene concentration during fed-batch
fermentation for YL-C11. The glucose concentration was fed at around 5
g/L.
Figure
2. The time-course of dry cell weight, dissolved oxygen, glucose
concentration, and β-carotene concentration during DO-stat fed-batch
fermentation for YL-C11. The DO-stat fed-batch induction was initiated
at 22 h, and the DO was controlled around 10-20%.
Figure 3. More ATP was determined in DO-stat fed-batch fermentation. The
ATP of both fermentations was extracted and assayed, as described in the
text. Error bars indicate ±SD from at least duplicate. (* denotes p
< 0.05) (ANOVA).
Figure 4. More
NADP+/NADPH
was determined in DO-stat fed-batch fermentation. The
NADP+/NADPH of both fermentations was extracted and
assayed, as described in the text. Error bars indicate ±SD from at least
duplicate. (* denotes denotes p < 0.05) (ANOVA).

biomass at fed-batch and DO-stat fed-batch
fermentation (a: fed-batch
fermentation; b: DO-stat fed-batch fermentation; Solid line represents
fitted data and circles represent experimental
data).

β-carotene synthesis at fed-batch and DO-stat fed-batch fermentation (a:
fed-batch fermentation; b: DO-stat fed-batch fermentation; Solid line
represents fitted data and circles represent experimental data).
Figure 7. Simulation of kinetic models and experimental results of
glucose concentration (a) (Solid line represents fitted data and circles
represent experimental data) and glucose consumption in different
periods (b).
