Fig. 4From: Lycopene overproduction and in situ extraction in organic-aqueous culture systems using a metabolically engineered Escherichia coli A Tri-phasic culture system for aqueous-organic systems. b Interphase. c E. coli BL21LF cells. Both phases were orange by the presence of lycopene. B Lycopene production normalized at 24 h for the organic-aqueous culture systems with E. coli BL21LF, distributed among three phases: aqueous phase containing E. coli BL21LF cells (solid bars), interphase (grey bars) and organic phase (open bars)Back to article page
