Fig. 3From: Engineering endogenous ABC transporter with improving ATP supply and membrane flexibility enhances the secretion of β-carotene in Saccharomyces cerevisiaeThe secretion of β-carotene in ABC transporter overexpression strains. a The intracellular (in orange) and secreted (in yellow) β-carotene in ABC transporter overexpression strains. b After the centrifugation, the β-carotene in the dodecane layer can be seen in the top, the YPD medium in the middle, and the cell pellet at the bottom. c Cell growth of ABC transporter overexpression strains. d Intracellular ATP content of ABC transporter overexpression strains.
