Figure 3: Fermentation profiles for a fed-batch R.glutinis yeast culture. a) Speed and aeration rates b) Biomass, residual glucose and dissolved oxygen c) NR fluorescence d) PI+ (dead cells) Biomass, residual glucose concentrations are affected by a relative error not exceeding 10% (n=2). NR fluorescence are affected by a relative error not exceeding 10% (n=2).
