Figure 3From: Development of a cultivation process for the enhancement of human interferon alpha 2b production in the oleaginous yeast, Yarrowia lipolyticaTime course of biomass concentration (A), huIFN α2b production (B), residual oleic acid concentration (C) and oleic acid to biomass ratio (D) for the various strategies tested during the induction phase. St 1, St 2, St 3 and St 4 correspond to a 20 g L-1 oleic acid pulse, a 10 g L-1 oleic acid pulse, 4 pulses of oleic acid, at 5 g L-1 at 6 h intervals each, and continuous feeding with oleic acid at a rate of 1.25 g h-1.Back to article page
