Figure 4From: Temperature limited fed-batch technique for control of proteolysis in Pichia pastoris bioreactor culturesComparison of biomass concentrations (X) and consumption of oxygen per methanol (Yo/m) in two similar TLFB processes (filled symbols, solid lines) and in two similar MLFB processes at 30°C (open symbols, dotted lines). The methanol phase is divided in temperature limitation and methanol limitation only in the TLFB process. Both types of processes were controlled at DOT = 25% with similar oxygen transfer rate (stirrer speed and aeration rate in the same bioreactor).Back to article page
