Lycopene production in C. glutamicum Δ crtEb overexpressing carotenogenic genes. (A) Cell pellets of cultures grown in glucose CGXII minimal medium after consumption of the carbon source. By the overexpression of the indicated carotenogenic genes the intensity of the red color was enhanced. (B) Lycopene concentrations of the cells depicted in A as determined by HPLC analyses of cell extracts.
